$2 Advantageous Results from the Use of 
patients without any bad effects, and they attended them 
regularly. 
™M. Desgenettes does trot confine himself to these general 
reniarks ; fe renders the favourable effects of -fumigations, 
according to~M. Morveau’s method, much more manifest, 
by giving monthly, for these last nine months, the respec- 
tive numbers of patients admitted into the military hospital, 
‘with the addition of those patients who had been there from 
the first ; this formed a sum total, which may be easily comt- 
pared with the number of those who died during the nine 
months. Upon turning over the registers it appears, that 
out of 3617 patients, 223 dicd; that is to say, a sixteenth, 
or 0°06. This report of icra is one of the most ad- 
vantageous that could be expected in an hospital; and it 
is so much the more conclusive in favour of mineral fumi- 
gations, according to M. Guyton’s process, that the mili- 
tary hospital of the capital often contains serious diseases, 
and is, for the most part, filled with refractory conscripts, 
and veterans not in garrison, who never come into the hos- 
pitals until they have suffered a great deal elsewhere. 5 
Such are the facts related by M. Desgenettes; and they con- 
firm more and more the advantayes of mineral fumigations, 
already established by other numerous observations collected 
in the work of M. Guyton. It may be inferred that these. 
fumigations not only act as preservatives agamst adynamic 
fevers and scurvy, but also concur in the cure of the 
same maladies, by destroying the baneful influence exercised 
apon sick persons by deleterious miasma. The use of this 
salutary process in hospitals ought to excite a lively interest. 
T shall here add some facts within my own knowledge, and 
which have shown, in the Hospital de la Salpetriere *, that 
some variations in the mode of mineral fumigations are ne- 
cessary, according to local circumstances. 
The iatbiion which I made of the lunatics, to enable 
me to follow out, with proper attention, my object of re- 
search, was to confine in particular apartments such of them 
as, were attacked with other incidental maladies, as agues or
