MISCELLANY. 
Before, however, that third ingredientis so added, it is desirable to clear 
the previous mixture by the addition of a small quantity of alcohol, and 
to set the whole in a cool place. All the various precautions here men- 
tioned may, upon an emergency, be dispensed with, when an immediate 
action is required, either to arrest pain or relieve deep-seated inflammation. 
But for the more delicate uses, particularly for instantaneous vesication, 
the preparations should be obtained in the manner I have specified. 
The lotion must always be kept in bottles with a glass stopper ; and 
their whole virtue depends on the accurate distillation and preparation of 
the ingredients, as well as on the careful admixture of the latter. The 
species of ethereal principle formed during the admixture, remains present 
in the lotion, but it is apt to vanish if the bottle be frequently opened, and 
then much of the peculiar effect of the counter-irritation is impaired. It 
is one of the many recommendations of these powerful preparations, that 
their effluvia, besides being agreeable, are of precisely that nature which 
is most likely to revive and benefit the patients laboring under diseases 
that require the application of counter-irritants. The compound camphor 
liniment is the only known combination of ingredients nearly similar to 
the ammoniated lotion just described. But the profession is well aware 
that the liniment will not produce, and never has produced, the effects I 
have predicated. 
Among those effects, one of the most surprising is that of giving rise, in 
a space of time varying only between three and ten minutes, and in almost 
every instance, (if such a result be the desired object,) to as ample and 
full a vesication as can be expected, in as many hours from the best Spanish 
flies. This is a result which I am not aware has been obtained before in 
so short a time, except by boiling water, (a remedy not quite so pleasant 
as the odor of ammonia;) and on it, therefore, as well as upon its import- 
ance in the treatment of many serious disorders, I do take my stand, as 
also upon that of arresting nervous and muscular pain, almost immediately, 
provided it does not depend on structural disease."
