BIOLOGICAL SECTION. 
Honorary Secretary’s Report for Session 1920-21. 
I have pleasure in presenting a report on the work of the Section 
during the past year, for I think you will regard it as satisfactory when 
compared with that of former Sessions. 
During the Session now closed, which was the 13th of the Section, 
the membership considerably increased in number, the meetings were 
well attended, and interesting and attractive programmes had been 
presented. The usual eight meetings on the first Wednesdays in the 
months November 1920 to June 1921 were held, at which the average 
attendance was 38 * 7, which number now forms a record, and compares 
favourably with 30*1 for the previous year, and with 19*1 for the 
Session 1915-16, since when the attendance at the meetings has steadily 
increased. 
I may remark here that the attendance would be larger if our 
meeting-room could accommodate more, for on one occasion (March 2, 
1921) 53, including 8 visitors, were present, when the room was packed. 
At the first meeting, on November 3, Dr. A. H. Drew gave a 
practical demonstration of Microscopic Technique, and on December 1 
Commander M. A. Ainslie, F.A.R.S., etc., contributed a valuable com- 
munication on “ The Correct Microscopic Image.” At the next meeting, 
on January 5, 1921, Mr. M. T. Denne, O.B.E.,read a paper on “ Monocystis 
agilis ,” and at the meeting held on February 2 Mr. E. Cuzner gave a 
communication on “ Hydroid Zoophytes .” The meeting on March 2 
was specially devoted to exhibits, when many interesting specimens 
Avere shown and described. 
On April 6 Mr. E. J. Sheppard exhibited a microtome, and gave a 
practical demonstration on section-cutting ; and on May 4 Mr. H. G. 
Cannon, B.A., described some experiments on Inheritance in Simocephalus 
vetulus. At our meeting on June 1 Mr. F. Martin Duncan gave a 
Lecture on “ Studies in Insect Biology .” 
In addition to these communications, which always formed topics 
for discussion, many beautiful and rare specimens were shown under 
microscopes and described, thus adding to the interest and usefulness 
of the meetings. 
On December 8 the members visited the Cancer Research Laboratory, 
Queen Square, on the kind invitation of the Director, Dr. J. A. 
Murray, who, with his assistants, described the work carried on there 
and showed many interesting preparations. On J une 8, by the special 
invitation of the President, Professor Eyre, the members visited for the 
fourth time the Bacteriological Laboratory at Guy’s Hospital and 
inspected many interesting preparations. 
The thanks of the members were accorded to Dr. Murray and 
Professor Eyre for the opportunities given them of seeing the various 
methods of technique, etc., practised in their laboratories, which were 
very much appreciated. J. Wilson.
