We rarely review books, but make an exception for the Pharmacological Basis of Therapeutics,* an encyclopaedia for the thoughtful prescriber. Like its predecessor published 5 years ago, the fifth edition is a multi-author book, but one which avoids much of the unevenness to which such books are prone. Well over half the text has been newly written or extensively revised. It is such a remarkable and valuable book because it is good for both brief and extensive background reading as well as for reference. The index is splendid and each of the 77 chapters cites many important papers and reviews (with their full titles), even including a few published this year. Every prescriber should have access to it.

The issues of methodological approaches toward and criteria of publication selection for rare and valuable book collections of sci-tech libraries are discussed. Based on the experience of CSAL, the need for comprehensive evaluation of books is substantiated: by materials and facilities, level of performance, physical condition and age, circulation, periodicity, and by value in scientific and sociocultural aspects.

Before sharing my impressions of the valuable book by Maria Lovdzhieva,  I would  like to recall who Nestor Markov was,  because I believe that his name is unknown to young audiences and even to many intellectuals. He is partially forgotten, although he is one of the key figures of the Bulgarian National Revival.Nestor Markov occupies a merited place among eminent Bulgarians. He was a teacher and reformer, author of manuals and noted lexicographer, whose work was recognized  by the award of the Order of Merit by the French Republic for contributions to French culture. Generations of francophones have learned the language with the help of his Bulgarian-French and French-Bulgarian dictionaries.  ...

There are no fewer than twelve complete works of Sebastian Bach to which the name Toccata is applied, and in nearly all cases the title seems to have come from the composer himself. It is always worth while to trace, if we can, the reasons which led a great man to choose one name rather than another for his creations; and in the case of Bach, I think we are justified in supposing that the names he gave were not purely arbitrary, but were chosen for some good reason. Certain modern composers, notably Brahms, have shown a strange indifference to the effect wrought by a well-chosen name for their music. His later works for pianoforte, often grouped under the heading of “Fantasias,” are divided into “Intermezzi” and “‘Capricci” according to whether they are slow movements or fast. But Bach, with his methodical habits, never showed that kind of almost perverse nonchalance in regard to the names his works were to bear. Remember the “Partitas,” and how each of the six introductory movements had a different designation from all the rest. As a matter of fact, there is not much indication of any inner variety of structure among the six, for all are preludial in general character, and it is evidently only a whim of the composer to give the six different titles. One of these, the sixth by the way, is styled “Toccata,” but has none of the distinguishing marks which, I hope to persuade you, Bach had in his mind when he used the title for independent compositions. Mr. Albert Schweitzer in his exceedingly valuable book on Bach (I am speaking of the recent work in two volumes, translated from the French by Mr. Ernest Newman) says that these Toccatas might just as well have been called Sonatas, or by any other name. Here I cannot agree with him, and the main object of my remarks on the present occasion.is to examine into the structure and style of the pieces, and see if we cannot discern some characteristic common to them all, and not shared by any other compositions of Bach.

In 1884 it was observed experimentally that whereas the electric current required to maintain a thick wire of given material, under given conditions, at a given temperature, was roughly proportional to the diameter of the wire raised to the power three-halves, the current was more nearly proportional to the first power of the diameter if the wire were thin . When this difference in the behaviour of a thick and a thin wire was first noticed it was regarded as quite unexpected. But, as pointed out by one of us in the course of a discussion at a meeting of the Royal Society, the unexpected character of the result was due to people having assumed that the loss of heat from radiation and convection per square centimetre of surface per 1° excess temperature was a constant for a given kind of surface and independent of the size and shape of the cooling body, although as early as 1868 Box had drawn attention to the great difference that existed between the rate of loss of heat from unit area of a horizontal cylinder and per unit area of a sphere. The interchange of heat between unit area of a body and the enclosure might be independent of the shape of the body as far as radiation alone was concerned, but it seemed nearly obvious that the cooling by convection must be materially affected by the shape of the cooling body. The very valuable investigations that have been made on emissivity by Mr. Macfarlane, Professor Tait, Mr. Crookes, Mr. J. T. Bottomley, and by Mr. Schleiermacher, had for their object the determination of the variation of the emissivity with changes of the surface and with change in the density of the gas surrounding the cooling body, but it was not part of these investigations to determine the change in the emissivity that is produced by change in the shape and size of the cooling body. Indeed, so little has been the attention devoted to the very large change that can be brought about in the value of the emissivity by simply changing the dimensions of the cooling body, that in Professor Everett’s very valuable book on Units and Physical Constants, the absolute results obtained by Mr. Macfarlane are given as the “results of experiments on the loss of heat from blackened and polished copper in air at atmosphere pressure,” and no reference is made either to the shape or to the size of the cooling body.

This valuable book is more than a long overdue corrective to the extant one-volume histories of American Jewry whose narratives pivot upon a familiar list of male names. Diner and Benderly offer us all the events and themes of American Jewish social history that we expect to find, but we see them through the actions, motivations, and experiences of women. And because women's experiences often have been entirely different from those of men, we learn more about the topic than can be available in the previous one-volume accounts. Although this book was written for a general audience, it reminds this reader of the more scholarly U.S. History as Women's History (1995) for the new understandings it brings to familiar material.
