This squat octavo paper-bound volume of some 500 pages contains the authors' abstracts of papers read at the XVIII International Physiological Congress, in Copenhagen (1950). Most in English, but some in French or German, the little articles give an overwhelming impression of the immensity of such a gathering. Most of the articles are highly specialized even within the field of physiology; one wonders how communication can possibly be kept up among scientists, since even the abstract and review literature is nowadays too huge and ponderous for anyone to handle. Shall there be summaries or digests of abstracts, superconcentrates, so to speak, of some sort? No answer comes to the reviewer except that much of this specialized material fortunately is of interest to few except the author and it may well be interred in a neat sepulcretum of this sort.
