same lesions : the bladder is similarly affected, and that vessel is 
filled with bloody urine. 
These things must surely make us pause : they will not induce 
us to abandon the use of nitre as a refrigerant and a diuretic; 
but they will cause us to recollect many a suspicious appearance 
in our former practice, and teach us to be more moderate in our 
doses. What shall we think of White, who advises an ounce 
of it to be given every fourth hour? or of Mr. Knowlson, who 
recommends the same dose for a horse, and double that quantity 
for a cow ? and we should somewhat fear Dr. Dickson’s dose of 
five drachms for a sheep. 
These observations are chiefly made in order to elicit the 
opinion and practice of others ; for it is only by an intercommu- 
nication of experience that the important objects of the editors 
and the readers of this periodical can be accomplished. 
DOMESTICATED ANIMALS AND MINERAL WATERS. 
The advantage of the hot and cold douche (the direction of a 
quantity or column of water or vapour on any person or animal) in 
the treatment of the diseases of the lower animals is now consi- 
dered abroad as firmly established ; and it is probable that baths 
and douches for application to the various domesticated animals 
will, ere long, be connected with all establishments which are so 
abundantly supplied with mineral springs as Aix-la-Chapelle. 
At Aix-les-Bains, in Savoy, and at many other places, there is a 
bath dedicated solely to their use ; and I had an opportunity, 
at Aix-les-Bains, of seeing the advantage of the cold douche in 
the treatment of a violent strain received by a poor ass from a 
fall. 
There is a spring at Ems, which is dedicated solely to the use of 
domestic animals, to whom, in cases of paralysis, chronic rheuma- 
tism, rigidity of the joints, sprains, &c. the employment of this 
spring, either in the form of a douche or a bath, is attended with 
the greatest benefit. The poor animals, after a hard day’s work, 
seem to enjoy it exceedingly. Its use is confined to the summer 
months. The temperature is from 70 to 116 degrees of Fahren- 
heit. The waters are found, on analysis, to contain carbonic 
acid in abundance, as well as carbonate of lime, carbonate of 
soda, sulphate of soda, and silica. 
It is added, that the use of these waters is most beneficial in 
affections of the chest, in nervous disorders, and in sterility. 
Such is their character, that noble dames are continually resort-
