system, as they would by inhalation. 
Through the kindness of Mr Snodgrass (already mentioned), 
allowing me to make free use of the important letters he has written 
me, I am in a position to give critical opinions on the treatment of 
acute general phthisis by means of — 
(1) Hypodermic injections of warm solutions of salicylic acid. 
(2) Bergeon’s anal injections of antiseptic gases. 
(3) Inhalation of volatilised iodine. 
(4) The inhalation of, and hypodermic injections of Eucalyptus 
oil.

Dr Bergeon gives no details of having studied the action of his 
gaseous antiseptics on the vitality of Bacillus tuberculosis., therefore 
it is on this point my next remarks will he directed. Bergeon 
recommends the anal injection of 4 litres of the mixed gases (see 
his paper, loc. cit.) ; the time prescribed for injecting this quantity 
is 20 minutes. I prepared pure carbon dioxide (from the decom-
