Arthur Bacot, F.E.S. 



With the deepest regret, we have to record the passing of Arthur 

 Bacot on April 12th, at the Fever Hospitnl, Abhassia, a,nd with pride 

 we record an additional name to be inscribed on the Roll of Martyrs 

 to the cause of science. 



It seems only a short time since the late J. W. Tutt remarked to 

 the writer that Bacot had the making of a brilliant entomologist, and 

 what a pity it was he had not the opportunity of developing his studies. 

 This must have been in 1900 when he was a clerk engaged m a city 

 office. However, at length his talents were recognised and he became 

 Entomologist to the Lister Institute of Preventive Medicine in London, 

 and soon made for himself a European reputation, more particularly 

 in connection with insect-borne diseases. His name is especially 

 known through his brilliant work on the exact mechanism of the 

 infection of man with Plague, by means of the rat-flea — a piece of 

 work which entirely altered existing ideas on the role of insects as 

 transmitters of bacterial disease. The results of his studies on this 

 problem were universally recognised in 1912, and since then but little 

 has l)een added to his work. He was the author of many contributions 

 to scientific literature, almost all bearing on the same question of 

 insect-transmission of disease. Besides this he contributed frequently 

 to the pages of T/ie Kntoiiioloi/ist's Record, etc., vide vol. iv., pp. 199; 

 vol. vi., pp. 32, 173; vol. vii'., pp. 227, 246, 261, 319 ; vol. viii., pp. 

 150, 151, 241, 248, 278 and 'dOii et seq. 



Two years later, in 1914, he went out to Freetown to study the 

 Stef/Diinjia mosquito for the Yellow Fever Commission and gave us a 

 complete account of the bionomics of that deadly creature. 



When he came home he settled down to study lice, and his work 

 on them was, after long efibrts, recognised and applied by the War 

 Office to the de-lousing of our soldiers for the prevention of typhus and 

 trench fevers, of which the infection is conveyed to a large extent 

 by lice. 



In 1920 his services were lent to the American Red Cross for their
