tubercular affections of the lungs, or other parts of the body. Dr 
Kolischer, starting on the assumption that tuberculosis occasion- 
ally heals naturally, owing to the tubercules being calcined,” hit 
upon the idea of causing artificial “ calcination ” by means of 
hypodermic injections of a substance, described as calcium plios- 
phoricum^ into the limbs of persons affected with tuberculosis. He 
made a number of experiments with a view to testing his discovery, 
and in every case the experiments turned out successful. 
(c) M. BalVs Treatment of Phthisis hy Injections of 
Euccdyptus Oil. 
Eecently M. Ball (Membre de TAcademie de Medecine de Paris) 
read a paper before the Paris Academy of Medicine, stating what 
he considers to be a cure for consumption, namely, by injections of 
eucalyptus oil under the skin. I may say here, that Mr Snodgrass 
has used eucalyptus oil volatilised by heat and inhaled ; and he 
says : — proved very irritating.^ and I had to desist. I greatly 
prefer salicylic acid injections to it.^’ 
(cl) Dr Theodore Williams’ Observations on the Influence of certain 
Substances on the Growth of Bacillus tuberculosis. 
In a paper,* kindly sent to me by the author, there are detailed 
a number of experiments with different reagents on the bacillus of 
phthisis. Dr Williams found that arsenious and boric acids “ exer- 
cised no destructive influence on the bacilli ” of consumption. He 
found that, with solutions of quinine sulphate (2 grains to 10 grains 
in an ounce of water) in each case the number of bacilli decreased 
rapidly under its influence, and “ that the bacilli in the sputum after 
being mixed with theguinine salt could not be cultivated even in beef- 
broth.” The experiment shows that quinine sulphate is a destroyer 
of Bacillus tuberculosis. Dr Williams also found that iodine (1 
part in 12 of water) reduced the numbers of bacilli, and prevented 
spore-formation. Mercuric chloride (1 grain to an oz. of water) 
caused no diminution, but rather an increase of bacilli-spore-forma-
