RHIKOSPORIDIUM KINEALYI 197 



whereby the spores have been liberated into the surrounding tissue. 

 It is almost certain that the spores serve for the auto-infection of the 

 host, for though the tumours of Rhinosporidium seemed to have 

 been removed entirely, it has been found that they recur, some 

 minute fragment of the parasite having probably been left behind. 

 The method whereby the parasite reaches new hosts has not yet been 

 determined, and it would be of interest if its life-history could be 

 more fully investigated.

 (After Minchin and Fantham.) 



The Asiatic specimens of R. kinealyi were first described in detail 

 by Minchin and Fantham (1905) from material briefly reported to the 

 Laryngological Society of London in 1903, by O'Kinealy. Material 

 obtained by Dr. Nair, of Madras, was described by Beattie 1 in 1906. 

 This material came from Cochin. Castellani and Chalmers have 

 found similar polypi in Ceylon. 



Wright 2 has described the parasite from Memphis, Tennessee. 

 Seeber 3 in 1896 described nasal polypi in Buenos Ayres, and in 1900 

 Wernicke named the parasite therein Cocci din in seeberi. Seeber 's 

 parasite is a Rhinosporidium, R. seeberi, and may ultimately be found 

 to be the same as R. kinealyi. Ingram 4 reports Rhinosporidium cysts, 

 with pores in the cyst walls, in conjunctival polypus and in papilloma 

 of the penis in India. Zschokke has reported the presence of Rhinos- 

 poridinin in horses in South Africa.
