bacteria were formed in the aqueous humours of the eye of a dead 
animal. He also pointed out that consumption was not infectious 
like eruptive fevers, and that when inherited it remained latent in 
the constitution during the whole period of youth. 
Dr. Symes thought that the principal cause of consumption 
was inhaling impure and damp air. He pointed out that some of 
the Government schools in Christchurch were very badly venti- 
lated, and advocated the drainage ot subsoil water. 
Mr. Meyrick asked if it were true that consumption was un- 
known in arctic regions? 
Mr. Hogben said that there were two things which ought to be 
kept separate, viz., the bacillus and its nidus. One might be pre- 
sent without the other, and then no disease would be produced. 
The President pointed out the difference between the bacilli 
themselves and their germs, or endogonidia. The use of aniline 
dyes for staining was attended with much uncertainty, and success 
depended largely on the strength of the dye used. He objected 
to Dr. Bakewell’s conclusion that bacteria originated spontane- 
ously. One experiment in which bacteria were not produced was 
of more value than a hundred in which they were produced. The 
anterior chamber of the eye-ball was not closed to bacteria, it con- 
tained blood-vessels, such as those going to the muscles of the 
iris, and the bacteria were introduced in the blood.
