Condizione: Very Good. vii, 290 pp; illustrations. Original cloth. Very Good. This copy does NOT have any library markings. First Edition. "Contains the papers read at a Symposium of the Society, which was held at Cambridge in July, 1946." One of the noteworthy papers is W. T. Astbury, "X-Ray Studies of Nucleic Acids" (pp. 66-76, with 2 plates and 1 text figure; see photos). To quote just one passage from this paper: "It seems improbable . . . to judge by the degree of perfection in the X-ray fibre diagram, that these four different kinds of nucleotides are distributed simply at random; rather must they follow one another in some definite order--at least, in more crystalline regions of the structure that give rise to the regular diffraction pattern. It is necessary to make this proviso, because in high-polymeric aggregates there is always the possibility that there are long portions of chains (or columns in this case) of sufficient regularity to build up crystallographically more perfect regions, while at the same time there occurs every so often some chemical peculiarity that might indeed confer specificity on a structure that is otherwise designed to perform some more standard function" (pp. 67-68). Kersten Hall, "William Astbury and the biological significance of nucleic acids, 19381951", Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences, Vol. 42, issue 2, June 2011, pp. 119-128.…
