RHINOSPORIDIUM KINEALYI. 525 
for this parasite the generic name Rhinosporidium, on 
account of its peculiar habitat, and we name the species 
after its discoverer, Major O’Kinealy. 
2. Merruops. 
Since our material was limited, as has been said, to two 
sections, one of which, as the property of the Laryngological 
Society, was inviolable, our work was restricted to restaining 
in various ways the remaining section, which was unmounted 
and divided into smaller pieces, each of which was made a 
separate preparation. ‘he section was of considerable size, 
and so full of the cysts of the parasite that even small frag- 
ments of the section contained some of them. Heidenhain’s 
iron hematoxylin, Delafield’s hematoxylin, gentian violet 
followed by orange, and safranin followed by licht-griin, 
were the combinations which gave the best results. A great 
obstacle to restaining, however, arose from the picrocarmine 
already present in the section, which could not be entirely 
dissolved out and caused the tissue to take up excess of the 
stains used, thus necessitating long differentiation and care 
in clarifying. Unfortunately also, the sections were cut 
too thick to show clearly the minute structural details of the 
parasite, and the fixation was not all that could be desired. 
In studying our preparations it was found that the 3-mm. 
homog. immersion of Zeiss gave clearer definition with the 
thick sections than the 2-mm., and was used in combination 
with the compensating eye-pieces 4, 8, 12, and 18, especially 
the first and the last of these. 
3. THE STRUCTURE OF THE PARASITE. 
In his second communication to the Laryngological So- 
ciety (2), O’Kinealy states that “a section of the growth when 
fresh was seen to be studded with minute white dots, which 
under the microscope were found to be cysts filled with 
granular bodies.” ‘This description may be compared with
