The import of the Lysenko controversy is more and more stirring the British scientific world, although the Press rage has subsided somewhat. The social implications of the Soviet biological theories are also receiving deep attention among all progressive people here.

Last night I attended a symposium, on the controversy addressed by three prominent scientists and I should say there were over 600 people present—including Professor Haldane. I see there is another meeting to-morrow night at Clerkwell Green.

The occasion of the meeting last night was the recent arrival from Moscow of a 631-page book entitled "The Situation in Biological Science"—the English translation of the proceedings of the Lenin Academy of Agricultural Sciences of the USSR held last August. This book may well go down in history as the most important book in biology since Darwin's "Origin of Species." Typical of the Soviet Union, it is being published in enormous numbers and the English edition is available here at the low price of 9/6.
