A professor of the geological institute. In 1890, Nadezhda Konstantinovna knew him personally as an honest and revolutionary-minded man. His son is a Communist.
Please order a check-up. It looks very much as though the scientists will have to be released.
Sapropel is an important thing for our economy.
 This document was written by Lenin in connection with the letter from Prof. N. N. Yakovlev, of the Geological Institute, about the arrest of academic geologists working on the study of sapropel (organic and inorganic depositions on the bed of reservoirs). Yakovlev said their arrest had been unjustified and requested their early release.
In a reply letter on August 25, I. S. Unschlicht wrote that one geologist had been released, while the others could not be released, because it had been established that they had connections with the counter-revolutionary organisation in Petrograd.
