His iutimate acquaiutaiicc witli the boreal flora of Africa caused 

 liir< help to be soiiglit by all botanists who had occasion to inves- 

 tigate the flora of the vast district of wliich, botauically speaking, 

 he might be said to possess the key. Our late lamented Fellow, 

 Mr. John Ball, when working up the collection of plants made 

 by himself and .Sir Joseph Hooker in Marocco, which came out 

 in the sixteenth volume of our botanical journal, fully acknow- 

 ledged iiis obligations to Mr. Cossou for valuable help in clearing 

 up many doubtful 2)lants. 



He died in Paris on December 31st, 18S9, after a short illness, 

 an attack of the so-called " influenza " proving more than his 

 bodily powers were able to resist.

FitANCis Day, after leaving Shrewsbury School, studied for the 

 Army Medical Service. Ordered to India after his appointment, 

 he was attached to tiic Madras Establishment in 1852, and 

 took part in the military operations of the second Burmese war, 

 fur which he received the medal. An enthusiastic na,turalist, 

 especially devoted to Ichthyology, he seized every opportunity 

 for extending his knowledge of the fish-fauna of the countries 

 through which he passed, and thus built up the extensive prac- 

 tical experience which justified him in ultimately devoting him- 

 self to that branch of research, and led to his subsequent 

 appointment as Inspector-General of Fisheries in India. In 

 tliis capacity ho was the author of valuable reports to the Govern- 

 ment, ranging from 1SG5 to 1877. He also published the follow- 

 ing works, which bear worthy testimony to his ability and 

 industry :— ' The Fishes of Malabar,' 1865 ; ' The Fishes of 

 India,' 18G8 ; 'The Fishes of the Andaman and Nicobar Islands, 

 &c.,' 1870; 'The Freshwater Fish and Fisheries of India and 

 Burmah,' 1873 ; ' The Fishes of India,' second edition, 1875- 

 1879 ; and ' The Fishes of the Nilghiri Hills and the Wynaad,' 

 1876. 



Holding the rank of Deputy Surgeon-General, he retired 

 from the Madras Medical staflE" in 1877, and returned to this 

 cjuntry. He then devoted himself with characteristic energy to 

 the study of the Fish and Fisheries of the United Kingdom, 

 which resulted in the publication of ' The Fishes of Great 

 Britain and Ireland,' 1880-83. An ardent follower of the craft 

 of Izaak AValton, he paid special attention to the Salmonidie; 

 and took great interest in the fish-cultural w^ork carried on at 

 Howietoun, under the auspices of Sir James Gibson Maitland, 

 aud published au important volume upon the experiments and 

 investigations there undertaken. 



The last work on which Dr. Day was engaged was his contri- 

 bution on the Fishes of India for the series of monographs on 

 the Fauna of India now in course of publication, edited by Dr. 

 W. T. Blauford. In addition to these larger works. Dr. Day
