Academy of Medical Sciences and in 1953 Corresponding Mem- 

 ber of the U.S.S.R. Academy of Sciences. 



Kolosov is a specialist in the area of neurohistology. He 

 has been studying the structure of the autonomic nervous sys- 

 tem and its interactions with the central nervous system; he 

 has been an advocate of the neuron structure theory of the ner- 

 vous system. He studied in detail the double innervation of the 

 alimentary canal and pelvic organs. Kolosov has also worked on 

 the afferent innervation of the human alimentary canal. 



In recent years he has studied afferent innervation of vege- 

 tative ganglia and vegetative neurons.

KONDRAT'EV, VIKTOR NIKOLAEVICH (Physical Chemist) 



V. N. Kondrat'ev was born February 1, 1902. He graduated 

 from the Leningrad Polytechnical Institute in 1924 and then 

 worked at the Physico-Technical Institute of the U.S.S.R. Acade- 

 my of Sciences. In 1931, he began working at the Institute of 

 Chemical Physics of the U.S.S.R. Academy of Sciences. Also 

 he has been professor at the Moscow Engineering Physics Insti- 

 tute. In 1948 he became a member of the Communist Party of 

 the Soviet Union. From 1943 to 1953 he was a Corresponding 

 Member of the U.S.S.R. Academy of Sciences, and in 1953 he 

 became an Academician. In 1944 he received a Stalin Prize. 



Kondrat'ev has worked in chemical kinetics, molecular 

 spectroscopy and structure, and photochemistry. He studied 

 the elementary processes during chemical transformation. Also 

 he developed methods of determining concentrations and re- 

 action velocity of free atoms and radicals, which are intermedi- 

 ate in photochemical reactions and combustion processes. 

 Kondrat'ev showed that the velocity of an over-all reaction is
