    Abstract: This book consists of a collection of essays written between 1965 and 1981. Some have been published elsewhere; others appear here for the first time. Although dealing with different figures and different periods, they have a common theme: all are concerned with examining how the method of hy­ pothesis came to be the ruling orthodoxy in the philosophy of science and the quasi-official methodology of the scientific community. It might have been otherwise. Barely three centuries ago, hypothetico­ deduction was in both disfavor and disarray. Numerous rival methods for scientific inquiry - including eliminative and enumerative induction, analogy and derivation from first principles - were widely touted. The method of hypothesis, known since antiquity, found few proponents between 1700 and 1850. During the last century, of course, that ordering has been inverted and - despite an almost universal acknowledgement of its weaknesses - the method of hypothesis (usually under such descriptions as 'hypothetico­ deduction' or 'conjectures and refutations') has become the orthodoxy of the 20th century. Behind the waxing and waning of the method of hypothesis, embedded within the vicissitudes of its fortunes, there is a fascinating story to be told. It is a story that forms an integral part of modern science and its philosophy.

    Abstract: "If a science has to be supported by fraudulent means, let it perish. " With these words of Kepler, Agassi plunges into the actual troubles and glories of science (321). The SOciology of science is no foreign intruder upon scientific knowledge in these essays, for we see clearly how Agassi transforms the tired internalistJexternalist debate about the causal influences in the history of science. The social character of the entire intertwined epistemological and practical natures of the sciences is intrinsic to science and itself split: the internal sociology within science, the external sociology of the social setting without. Agassi sees these social matters in the small as well as the large: from the details of scientific communication, changing publishing as he thinks to 'on-demand' centralism with less waste (Ch. 12), to the colossal tension of romanticism and rationality in the sweep of historical cultures. Agassi is a moral and political philosopher of science, defending, dis­ turbing, comprehending, criticizing. For him, science in a society requires confrontation, again and again, with issues of autonomy vs. legitimation as the central problem of democracy. And furthermore, devotion to science, pace Popper, Polanyi, and Weber, carries preoccupational dangers: Popper's elitist rooting out of 'pseudo-science', Weber's hard-working obsessive . com­ mitment to science. See Agassi's Weberian gloss on the social psychology of science in his provocative 'picture of the scientist as maniac' (437).

    Abstract: Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.

    Abstract: Many chemists and biochemists require to know the ionization constants of organic acids and bases. This is evident from the Science Citation Index which lists The Determination of Ionization Constants by A. Albert and E. P. Serjeant (1971) as one of the most widely quoted books in the chemical literature. Although, ultimately, there is no satisfactory alternative to experimental measurement, it is not always convenient or practicable to make the necessary measure­ ments and calculations. Moreover, the massive pK. compilations currently available provide values for only a small fraction of known or possible acids or bases. For example, the compilations listed in Section 1. 3 give pK. data for some 6 000--8 000 acids, whereas if the conservative estimate is made that there are one hundred different substituent groups available to substitute in the benzene ring of benzoic acid, approximately five million tri-substituted benzoic acids are theoretically possible. Thus we have long felt that it is useful to consider methods by which a pK. value might be predicted as an interim value to within several tenths of a pH unit using arguments based on linear free energy relationships, by analogy, by extrapolation, by interpolation from existing data, or in some other way. This degree of precision may be adequate for many purposes such as the recording of spectra of pure species (as anion, neutral molecule or cation), for selection of conditions favourable to solvent extraction, and for the interpretation of pH-profiles for organic reactions.

    Abstract: One facet of development in this field is that the methods of gathering and processing geophysical data, and displaying results, lead to presentations which are more and more comprehensible geologically. Expressed in another way, the work of the interpreter becomes progressively less onerous. The contributions in this collection of original papers illustrate this direction of development, especially in seismic prospecting. If one could carry out to perfection the steps of spiking deconvolution, migration and time--depth conversion, then the seismic section would be as significant geologically as a cliff-face, and as easy to understand. Perhaps this is not yet achieved, but it remains an objective, brought closer by work such as that described by the authors. The editor offers his best thanks to the contributors-busy geophysicists who have written with erudition on this range of subjects of current interest. A. A.

    Abstract: This volume in the Energy from Wastes Series covers the area of methane production from agricultural and domestic wastes. Principally this involves the conversion of excreta and other organic effluents to a valuable gaseous fuel plus, in many cases, a useful sludge for fertiliser or feedstuffs. Dr Hobson and his colleagues have written a comprehensive text on the principles of microbiological processes and the biochemistry of anaerobic digestion, embracing the design of digesters with examples of current working installations. The potential for anaerobic digestion of wastes as diverse as sewage to fruit processing effluents is also reviewed. This work should be of interest to all who have to manage organic waste treatment and disposal, as well as to a wider readership who wish to know more about methane production by anaerobic digestion. ANDREW PORTEOUS v Preface The production of methane, or more exactly, a flammable 'biogas' containing methane and carbon dioxide, by microbiological methods ('anaerobic digestion') is not new. The reactions have been in industrial use for over a hundred years, but only in sewage purification processes. In some times of national stress, such as war-time, the microbiological production of gas purely for fuel has been investigated, but with the resumption of plentiful su pplies of fossil fuels the investigations have faded awa y.

    Abstract: Throughout the history of warfare at sea, navigation has been an important basic determinant of victory. Occasionally, new members of the fraternity of the sea will look upon navigation as a chore to be tolerated only as long as it takes to find someone else to assume the responsibility. In my experience, such individuals never make good naval officers. Commander Hobbs has succeeded in bringing together the information and practical skills required for that individual who would take the first step down the road toward becoming a competent marine navigator. At the outset of this book, the author stresses the necessity for safe navigation, but there is another basic tenet of sea warfare that this book serves. The best weapons system man has ever devised cannot function effectively unless it knows where it is in relation to the real world, where it is in relation to the enemy, and where the enemy is in relation to the real world. Not all defeats can be attributed to this lack of information, but no victories have been won by those who did not know where they were.

    Abstract: 1.1. General In this book the family life of the lower-class Creole population of 1 Paramaribo will be discussed. This group, which will henceforward be referred to as "the lower-class Creoles", possesses a "West Indian" family system, implying that the latter display all the main characteristics of the Caribbean Afro-American family. The Creoles constitute a numerically important ethnic segment of the society of Surinam. This society is composed of different ethnic groups, comprising, besides a handful of Amerindians, an "immigrant population" including people from many different parts of the world. It is made up of Creoles, Indians (or Hindustanis, as they are called in Surinam), Indonesians (Javanese), Chinese, Europeans, Lebanese and Bush Negroes, the latter of whom still live predominantly in tribes. The Creoles are the descendants of those Negro slaves brought to Surinam from Africa who did not escape from bondage by running away from the plantations into the Bush, as their brothers the Bush Negroes did. The circumstances under which the bulk of the slaves lived were appalling. Nor were they - or are they still in p~ at present - much better for their descendants the lower-class Creoles.

    Abstract: The Photoelectric Spectrometry Group was formed in July 1948 in Cambridge. The Group was born out of a need for a forum of users to discuss problems and methodology associated with the new era of photoelectric spectrometers. Over the years the aims and objectives of the Group have been broadened to include many aspects of ultraviolet and visible spectrometry. In 1973, the Group renamed itself the UV Spectrometry Group (UVSG). The techniques of fluorescence, diffuse reflectance, ORD and CD were included in the Group's interest. In 1979, the UVSG became a registered charity. The present Group membership is some 200 practising spectroscopists, mostly from the UK with a small but growing overseas membership. In August 1977, the UVSG Committee set up three Working Parties: Cells for UV-Visible Spectrophotometers; Photometric and Wavelength Standards; and the Calibration of Fluorimeters. It was felt that a wealth of information and expertise in the practice of spectrometry was available within the Group and that it was appropriate for this to be gathered together in the form of a number of monographs. Initially the intention was that these should be circulated only amongst the Group membership. However, the suggestion was made that these monographs would be of interest to other scientists outside our specialist Group. The conclusions of the first two Working Parties were combined in Volume 1 of this series, and this monograph summarizes the work of the third Working Party.

    Abstract: The student of biological science in his final years as an undergraduate and his first years as a graduate is expected to gain some familiarity with current research at the frontiers of his discipline. New research work is published in a perplexing diversity of publications and is inevitably concerned with the minutiae of the subject. The sheer number of research journals and papers also causes confusion and difficulties of assimilation. Review articles usually presuppose a back­ ground knowledge of the field and are inevitably rather restricted in scope. There is thus a need for short but authoritative introductions to those areas of modern biological research which are either not dealt with in standard introductory textbooks or are not dealt with in suffi­ cient detail to enable the student to go on from them to read scholarly reviews with profit. This series of books is designed to satisfy this need. The authors have been asked to produce a brief outline of their subject assuming that their readers will have read and remembered much of a standard introductory textbook on biology. This outline then sets out to provide by building on this basis, the conceptual framework within which modern research work is progressing and aims to give the reader an indication of the problems, both conceptual and practical, which must be overcome if progress is to be maintained.

    Abstract: Every book has its own personal story and my book on the Jaqaj people is no exception. I collected my initial data at the time when the Dutch government was responsible for what is now lrian Jaya, a province of Indonesia. At the time that I worked in the field and gathered my information, I enjoyed the enduring interest and support of the late Mgr. H. Tillemans, m. s. c. , archbishop of Merauke. I wish to dedicate this book to his memory. my studies, written in Dutch, appeared in 1958 A first summary of under the tide Papoea's aan de Mappi. Further research in the area persuaded me that some of my previous views needed correction and that publication of more data was necessary as weIl. In 1969 I finished the Dutch draft of the present book. For its translation I was very fortuna te to have help of my colleague Mr. M. van Dijck. It appeared that the text was too long and had to be reduced to better, workable my homework for the following years. The final proportions. That was draft was corrected by my friend Dr. W. Beek, former teacher of English at several colleges, and finally retyped by Father A. Bodden, m. s. c. I owe all of these people my sincere thanks for the many hours spent on this work.
