Under the reaction of a powerful pathological synchronous action caused by a medicine, a dis ease may be at times subdued as if by magic; but it might be well to estimate at what cost of the vital forces such a cure is effected. This is forcibly demonstrated in the treatment of gout and rheumatism with colchicum. It may give prompt relief, but it may prove ruinous to the general health of the patient afterwards. The potential effects of tartar emetic in an infantile inflammation of the respiratory organs may give relief to the immediate disease, but too often the remedy tends to a disease in its place that cannot be subdued for months afterwards, if at all. Almost any heroic treatment with remedies of great force, may thus at times be productive of both good and evil results. Such a treatment can only be recommended in the strong and vigorous with a sanguine temperament, and in these exceptions even, should only be employed to overcome a very violent pathological action. Thus it may be necessary to treat the intense attacks of fever caused by miasmatic influences with arsenic. As small doses would have little effect, it is necessary to prescribe almost toxic doses producing the state of collapse and inducing accidents more or less approaching the choleriform symptoms. a

Remedies of this class often render relief by the laws of revulsion, as traumatic coma may often be removed by the introduction of a few drops of croton oil into the rectum. Counterirritants likewise come under this action, but from the fact that they are usually remedies of hgohlius. adr. Iy. Lewin. cbarbier. agubler.

external use, they are less liable to leave bad effects.

But there may be a pathological synchronous action of spontaneous development, and not brought about by medicines. Nature usually occupies itself with but one disease, but at times it may institute another of a more serious nature, usually in some distant part of the body. Thus a connection may exist between a chronic disease of the kidneys and cardiac hypertrophy - between gout, and some other diseases, and diabetes and lithiasis may be caused by a disease of the liver, and end with diabetes. The liver under a functional inactivity, not dehydrating the sugar of the portal vein into glycogen is the antecedent of diabetes of the kidneys. Gout often carries with it a hypertrophy of the heart.
