Sharabrin have intended this book primarily for students in veterinary colleges and to provide reference material for laboratory workers and practic- ing veterinary physicians. Importance of this book is enhanced bY the fact that all previously published textbooks and manuals on the methods of clinical and laboratory diagnosis in veterinary medicine have been sold out and have become somewhat obsolete. Notable ad- vances have been made in the past few years in the Soviet Union in the field of veterinary medicine; veterinary clinicists have~con- tributed much new to the veterinary laboratory-clinical diagnostic methods. All these advances have been incorporated in this book- The book was published in 1952 by the State Publishing House of Sovhoz and Kolkhoz Literature, Moscow, 252 pp, Fifteen thousand copies.

A schematic representaLion of the experimental setup is presented. A detailed account is given oftithe techniques used for produc- tion,of shock waves and for measurements. Nitrogen~\argon, itir, and a mixture of nitrogen and CO 2 were investigated in temperature ranges from 5000 to 10,OOOK, with pressure from 5 to 50 atm, and wavelength from 6000 to 3000 1. A special iarrangement for obtaining time-resolved spectra is described which has certain advantages over a drum camera. The analysis of spectra obtained for all gases shows the presence of 1) continuum radiation, 2) impurity lines of Fe, Ck, Cu, Ca, and others, and 3) CN lines of the violet system and probably lines of the N (1+) N (2+) NO(O) systems in the spectra of air, nitrogen, and CO 2_N2 mixture. in th; tKe-~;solved spectra, L 36QAQ-66 ACC MRs AT6022646 a secondary emission was observed. The distribution of spectral aboorl)tivity referrW to the unit of length of the absorption layer with respect to the wavelength which was obtained for nitrogen and a C02-N. mixture from quantitative analysis of spectra using, heterochromatic scanning.

Up until now, the registration of the height and of the gamma radiation have been conducted separately, and only by joint laboratory processing could the reduction of the field be as- certained. The introduction of 2 devices, which can be easily installed in existing radiometers, is proposed: an automatic height corrector, by which the variation of the intensity of gamma radiation at varying heights can be calculated by the King Functionp and a device for the automated reduction of the field. These devices will increase the effectiveness of aerial surveying and eliminate complicated laboratory calculations and Card 1/2 adjustments.
