 parasite of tropical or aestivo-autumnal fever. The refer- 

 ences to malaria in Australasia are as follows : — Dyson, 

 Trans. Inter. Med. Cong. Austr., 1889, p. 64 (N. Q'land — 

 the three types of fever) : Hudson, Austr. Med. Gaz., xvi., 

 1897, (N. Z'd); xvii., 1898, p. 225 (N. Z'd) : Hunt, x., 

 1890-1, p. 75 (N. Q'land); Trans. Int. Med. Cong. Austr.,

 Malaria (especially tertian) occurs in Sydney* (Dr. Finckh, 

 Dr. O'Neill), the disease being contracted in New Guinea, 

 New Hebrides, and other Pacific Islands ; and it occurs also 

 in North West Australia* (Dr. Cleland) and Northern 

 Territory : Johnston, loc. cit., p. 581 (N.S. Wales, W. 

 Austr.). 



33. Cytoryctes variolae, Guam. — cowpox organism. 



34. Cytoryctes vaccinae, Guam. — smallpox organism. Both of 

 these occur in the blood corpuscles. Their protozoan nature 

 is still doubted by some authorities. These two diseases 

 occur in every state of Australasia. Nearly all the following 

 references relate to smallpox. Coutie, Austr. Med. Gaz., iv.,

Two fairly common tropical diseases, Beri-beii and Dengue 

 fever, are at present regarded as being produced by the presence 

 of undiscovered protozoa.
