NICOTIANA TABACUM.

aware that it has been as yet trifed in this disease.* Dr. Cullen ob- 
serves, that in smoking, part of the smoke must necessarily pass into 
the lungs, and that its narcotic power applied there often relieves spas- 
modic asthma ; by its stimulant power also it sometimes promotes ex- 
pectoration, and proves useful in catarrhal or pituitous difficulty of 
Breathing. A watery extract of tobacco, in the dose of two or three 
f^raiiis, has aLo been recommended for chronic catarrh. As an 
errhiue and sternutatory, the effects of tobacco are sufficiently 
known; snuff, by exciting a considerable discharge of mucous from 
the nose, has in many instances relieved head-ache, tooth-ache, and 
dphthalmia, but very bad effects have frequently resulted from the 
immoderate use of it. Dr. Cullen says, he has found all the symp- 
toms of dyspepsia produced by it, and particularly pains of the 
stomach. 
The practice of chewing tobacco, produces nearly the same effects 
as smoking ; it also occasions a greater waste of saliva, and the 
effect of this in weakening digestion, and impairing the tone of the 
stomach, will sufficiently account for the pale and emaciated ap- 
pearance which so frequently attends the use of it. 
As an external application even tobacco must be considered not 
altogether a safe remedy ; instances of this we have already recorded.

* Since the preceding observation was written, oar atteation lias been directed to an 
interesting communication on the subject to which it relates, by Dr. James O'Beime, 
Of Dilblin, by which we learn that tobacco has already been employed in the treatment 
of tetanus, in this country, and with success. It has also, we are informed, been so 
employed in the West Indies. For Dr. O'Beirne's Paper, vide Dublin Hospital
