PARENCHYMATOUS AND INTERSTITIAL INJECTIONS

interstitial suppurant. The adjuvans (ether) forming a solution 
with the croton oil, by its rapid permeating influence amidst the 
tissues, carried the croton oil over a much greater area than 
intended, which could have been modified by substituting some 
bland oil. I therefore concluded to adopt a less potent agent for 
that purpose, which I am still using with flattering success. I 
refer to cantliaridal collodium. 
Tinct. cantharides or turpentine with sweet oil were my favor¬ 
ite remedies for a long time. But I uniformly found them unre¬ 
liable and sluggish in their action. I have also tested the utility 
of tinct. iodine for quite a period with a view of absorbing the 
enlargement. In some cases this treatment was successful; in 
others it failed, but it favored the development of pus, which was 
more desirable; for I entertain the opinion that a return of the 
tumor need less be apprehended than if absorption had been 
achieved; moreover, the progress and final termination may be 
depended upon. 
The sub-cutaneous injections of stimulants for atrophy of the 
scapular region of muscles also bring forth gratifying results to¬ 
wards the restoration of the volume of muscular tissue by em¬ 
ploying such agents as will uniformly excite the cell and vascular 
activity, like alcohol, fusel oil, turpentine, and others. One part 
of fusel oil and seven parts of sweet oil proved very encour¬ 
aging in several instances, but alcohol, on account of its rapid 
permeability, injected at intervals of three to five days, has been 
my latest selection. These injections should be followed by a 
thorough palmar friction. Their repetition should be regulated 
by the subsidence of the inflammation produced by the agent in¬ 
jected. I have also made use of tinct. cantharides, turpentine, 
and other stimulants, where abscesses ensued. For this compli¬ 
cation, until further objectional developments occur, I have chosen 
alcohol as a local stimulant to the impoverished district of mus¬ 
cular tissue. 
The efficacy of the deep injections of anaesthetics or anodynes, 
such as chloroform, ether and morphia, to allay excruciating pain, 
has often been achieved by the local saturation of the suffering 
tissues. This is particularly the case when the pain is not
