NATURE 



Henry Bradwardine Jackson, 



Captain, R.N., Naval Attache to the British Embassy, Paris. 

 Invented (1886) a practical system of electrically illuminating 

 'gun sights for tiring at night, which was adopted and used for 

 soine years in H.M. Navy, but has since been replaced by later 

 methods. Proved (1888) that considerable stability is necessary 

 in order that a totally submerged automobile torpedo may main- 

 tain a straight course. Has given much attention to the theory 

 and practice of aerial telegraphy. Invented a serviceable appa- 

 ratus for signalling between ships at sea without wires. Proved 

 that if the Hertzian oscillations are transmitted and received by 

 vertical wires, the distance to which effective signals can be sent 

 tends to vary within limits as the product of the lengths of the 

 wires.

special studies in Tropical Hygiene and Parasitology in iSgr. 

 Papers on these subjects and on Histology of Blood, Indian 

 Medical Societies and Journals. Parkes Memorial Prize and 

 Gold Medal (Netley) for Essay on Malaria, 1894. Same year 

 commenced experimental examination of Manson's Mosquito- 

 Malaria theory, and studied malaria parasites at Secunderabad. 

 Determined evolution of "crescents" in stomach cavity of gnats 

 (Manson, Brit. Med. Journ., March, 1S96). Established 

 animate nature of the flagellate bodies (ibid., Jan., 1897). 

 Finally succeeded in cultivating malaria parasites in gnats {/'/S/rf.,

 history of a malarial parasite (Proteosoma Grassii) of birds; 

 infected numerous healthy birds by bites of gnats, thus
