Blisters have been opposed in these fevers by many 
practitioners, among the most conspicuous is For- 
dyce. Inintermittents they often display signal re- 
lief, and pave the way for bark, which, without their 
previous use, is unavailing. They remove local 
pain, shorten the disease, and resolve congestions 
of the spleen, liver, and other viscera. In continued 
fevers, their use is problematical ; and at all events 
great circumspection is required to interpose them 
between high action and approaching collapse. 
It has been observed by Percival, and my own ex- 
tensive experience with fevers of a warm climate, 
sustains his position, that in fevers attended with 
a general disposition to inflammation, without 
partial or local affection greater in one part than 
another, blisters always act infuriously ; but that 
in cases of local inflammation with general febrile 
action, they are always useful. Phe efficacy of 
these remedies in pleurisy is universally known. 
In this acute disease, they should be defered, for 
the most part, until depletion has been used ; yet 
cases do occur in which they may be applied much 
earlier. ‘There is indeed no reason why bleeding 
should not be practiced after their application and 
before the proper period arrives at which they are — 
to be removed. Hydrothorax is said to follow blist- 
ering the chest before blood-letting ; a fact men- 
tioned by Armstrong. Some have recommended 
the application of blisters in pneumonic disease to 
the extremeties, or between the shoulders, in pre- 
ference to the chest. Ihave often used them in 
both ways, but give decided preference to the 
chest in inflammation of the pleura, and to the 
space between the shoulder blades, in congestive 
states of the lungs. In phthisis they may be often 
requisite, placed on the breast. In inflammatory 
affections of the trachea, and larynx, and of the
