A small piece, (about half a arabia of this ointment may be rubbed, 
morning and evening, upon enlarged glands, and the quantity may be gra- 
dually increased, according to the age of the individual, and circumstances _ 
of the tumour. In very obstinate cases, it is necessary to give some prepa- 
rations of iodine internally, during the external application, the treatment 
by friction alone not being sufficient. It must not, however, be concealed, 
that very untoward effects have not unfrequently accompanied or followed 
the injudicious use of this powerful medicine. We are told by Dr. Gairdner,t+ 
that the symptoms usually produced, are, a peculiar, great, and persevering 
anxiety and depression of spirits, which are very different from hypochon- 
driasis, inasmuch as they dwell principally on the present, and have no re- 
ference to the future. The emaciation and cholera produced by it, are also 
stated as frequently extending to a dangerous, and even fatal result. When 
the patient is under the full influence of iodine, Dr. Gairdner has found a 
degree of tremor to come on, which he considers as a good guage of the ex- 
tent of the nervous excitement which has taken place, and is seldom or never 
absent, when that excitement has proceeded to any considerable degree. In 
the cholera induced by iodine, Dr. Gairdner has observed sedatives, such as 
hyoscyamus, opium, §c. to be more beneficial than any other class of medi- | 
cines; purgatives are said invariably to do harm. Iodine frequently stimu- 
lates the arterial system so much that it is necessary to discontinue its use ; 
and if it be administered in doses too large, or too often repeated, it is apt 
to produce inflammation of the stomach, attended by nausea, &c. We are 
told that it not unfrequently causes a remarkable wasting of the testes and 
mamme.
