ON DEODORIZATION AND DISINFECTION. 
they were situated similarly to the other wards and sheds. I had 
the fluid used once a day, in the way of waving and sprinkling, 
and I daily noted the number of deaths in those wards, and com- 
pared this and the number of inmates with the total mortality and 
total sick of the hospital as published weekly in the newspapers. 
Thus, for the week ending 4th September, in the wards where the 
fluid was not used, there was one death in about every nine pa- 
tients ; and in the wards where the fluid was employed, there was 
one death in about every fourteen sick. 
On account of having to be occasionally absent from Quebec for 
a day or two, I was unable to note daily for any great length of 
time continuously, the mortality in the fluidized wards ; but I have 
no reason to doubt that while the fluid was used there was a 
difference in the comparative mortality somewhat like what is 
stated above. The difference is one too great to have depended on 
accidental circumstances, and I do not see to wdiat it can be attri- 
buted, except to using the chloride of zinc solution. It was not 
till the middle of January that I compared the deaths in the 
fluidized wards with the total mortality as published in the news- 
papers, when I was greatly delighted to find that my exertions had 
had such beneficial results. If we suppose the case of a fever hos- 
pital throughout the whole of which the fluid had been used, and 
that after this the mortality became less, some might say that this 
arose from the disease becoming milder ; but, in the instance given 
above the experiment is more decided, the trial is clearer, and the 
mortality in fluidized wards is, compared with that in non-fluid- 
ized, between the same dates. 
IV. Chloride of zinc has been given inwardly in the dose of a 
grain or less, two or three times a day, in chorea, epilepsy, &c. 
V. In surgery, chloride of zinc is occasionally used. I lately 
saw a case of lupus, where the Burnett fluid (undiluted) was found 
to be as effectual and a more convenient form than the solid chlo- 
ride of zinc. 
The Burnett fluid, diluted (1 to 130 parts of water), has been 
found very beneficial as an application to chronic and scrofulous 
ulcers (by Mr. Erasmus Wilson, Dr. Allan, and others) ; and in 
mercurial sore throat (by Mr. Flynn). The fluid diluted (1 to 60 
or 80) is useful as a lotion in erysipelas, and as a bath in psora, 
prurigo, pruritus, and other cutaneous diseases. It has also been 
used as an injection in gonorrhoea. I have no doubt it will be found 
an excellent remedy, much diluted (as 1 to 120) as an injection in 
foetid otorrhoea, and as a gargle in some throat diseases. Diluted 
(l to 140), it removes the foetor from mortification taking place as 
after frost-bite. The fluid undiluted, or with an equal part of water,
