KKPOliT ON THE WORK OF THE RIOLOUICAL SECTION 

 DURING THE SESSION 1919-20. 



It is my pleasing duty to submit to the Council the 12th Annual Report 

 of the Biological Section, for it will show that increased interest is 

 taken in the sectional work, that the evenings have been fully occupied, 

 and that the average attendance at the meetings is steadily increasing. 

 In the Session 1918-19 the average attendance was 25-6, that being a 

 record. The average attendance last session was 30 '1, the lowest 

 number at any meeting, November, was 20, and the highest at the May 

 meeting, :'!(), a record number. 



Durino' the session eight meetings were held on the first Wednesdays 

 in the months November to June, at which seven interesting communi- 

 cations were read and discussed. At the November meeting Mr. Paulson 

 gave some notes on " The Nucleus and Ryrenoid in certain Spherical 

 Algaj." The Decend^er meeting was occupied by .Mr. Akehurst with 

 '•Notes on the liarva of Gorethia Fhimicoriiisy On January 7, 1920, 

 \)\\ J. A. Murray gave a practical demonstration on " The Manipulation 

 of Frozen Sections of Animal Tissues." At the February meeting Sir 

 Nicholas Zermoloff gave an interesting communication on " Beggiatoa 

 and Allied Forms." The March meeting was mainly occupied by Dr. 

 Tierney on the " Bacterial Flora of Water," and this proved of such 

 interest that the discussion upon it was adjourned until the April 

 meeting, when the specimens of cultures exhibited could be further 

 examined. The meeting on May 5 was occupied by Mr. J. E. Barnard, 

 who described "The Correct Image" in the unavoidable absence of 

 Commander Ainslie, R.N., who was on the programme for that evening. 

 The last meeting of the Session was on June 2, when Mr. Scourfield 

 gave some '' Notes on Zoochorellae." 



In addition to these communications, many interesting specimens 

 were shown under the microscope and described by the exhibitor, thus 

 addine- to the attraction and usefulness of the meetings. 



J. WILSON, Hon. Secretary.
