The Ductless Glands. — Report of the Committee, consisting of 

 Professor Sir Edward Schafer (Chairman), Professor 

 Swale Vincent (Secretary), Dr. A. T. Cameron, and Pro- 

 fessor A. B. Macallum. (Drawn up by the Secretary.) 



The work of the Committee has been carried on during the past year 

 by the Secretary and by Messrs. Austmann and Halliday under his 

 direction. 



The subjects of investigation have been the effects of prolonged 

 anaesthesia on the adrenahn content of the blood, and the morphological 

 position of the islets of Langerhans in the pancreas. 



The results are generally confirmatory of previous work on the 

 subject, but they involve questions of detail in technique which will 

 be more appropriately described elsewhere. 



The Committee ask to be reappointed with a grant of 251. 



Electromotive Phenomena in Plants. — Report of the Committee, 

 consisting of Dr. A. D. Waller (Chairman) , Mrs. Waller 

 (Secretary), Professors J. B. Farmer, T. Johnson, and 

 Veley, and Dr. F. O'B. Ellison. 



The object of the work this year has been to determine whether, for 

 the practical purpose of ' seed germination testing, ' if the whole seed 

 be used a sufficiently strong electrical response is obtained. 



The extraction of the radicle in small seeds is a delicate and trouble- 

 some process, so that it would be an advantage to be able to use the 

 whole seed. 



The following table shows the difference in response of the whole 

 pea intact and its radicle: —
