xlvi - PROCEEDINGS OF THE GEOLOGICAL socipty. [May 1902,. 
activity during the past decade. I can only refer to a few of your 
more important contributions to the advancement of science. 
In your Memoir on the Charnockite Series you have made us 
familiar with the field-relations, the mineralogical composition, and 
the microscopic structure of an important and interesting group of 
Archeean rocks ; 1n your contribution to the ‘ Manual of the Geology 
of India’ you have given us a valuable treatise on the natural 
history of corundum; and in your paper on the eleolite-syenites 
of Sivamalai you have added a new group to the foliated crystalline 
serles. 
But you have not confined your attention to the crystalline rocks. 
In the ‘ Report on the Geological Structure & Stability of the Hull- 
Slopes around Naini Tal,’ you have brought your geological know- 
ledge to bear on questions affecting the security of life and property, 
and have laid down general principles which must be of great 
utility to all those who are responsible for the safety of the 
inhabitants of those hilly districts, in which denudation is going 
on with exceptional rapidity. 
T haye much pleasure in handing you the Balance of the Murchison 
Geological Fund, which has been awarded to you by the Council 
ot the Geological Society, in recognition of your valuable contribu- 
tions to Indian geology. 
AWARD OF THE LYELL Mrpats. 
In handing the Lyell Medal awarded to Mr. Ricuarp Lypexxmr, 
B.A., F.R.S., to Dr. F. A. Barner for transmission a the recipient, 
the Prustpenr addressed him as follows :— 
Dr. BarHEr,— 
Mr. Lydekker’s labours in the domain of Vertebrate Paleontology 
commenced, I believe, with a study of the Siwalik fossils, which 
resulted in numerous and valuable additions to the classic work of 
Falconer & Cautley on the Siwalik Fossils. 
Many other Tertiary vertebrata from various parts of India and 
Burmah, from Perim Island, Sind, the Nerbudda, and the Irrawaddy 
Valley, have been examined and described by him. He has also 
given us an account of the Pleistocene fauna of the Karnul Caves, 
and has contributed to our knowledge of Indian Mesozoic reptilia. 
During his residence in India as an officer of the Geological
