Dr. Engin relates the following cases of catarrhal and rheumatic fever. A delicate female, aged 30 years, was taken ill on the 27th of April 1837, with the abovementioned complaint, but was under an allopathic doctor till the 30th, when Dr. E. found her labouring under acute pains in the joints—inflamed throat—difficulty of swallowing—joints swelled and red—inability to move—pulse 100. The patient was enveloped in a cold wet blanket, over which several dry ones were placed, twice a day, for three days consecutively. She soon began to perspire copiously each time of application. On the fourth day she was plunged into a cold bath while deluged with sweat. This was repeated twelve days in succession, the inflamed joints being kept, in the intervals, covered with cold wetted cloths. During all this time she was ordered to drink plenty of cold water. The fever and all the other symptoms gradually diminished, and finally disappeared. Towards the end of the treatment a critical eruption appeared on the skin. This was certainly as unfavourable a case for the hydropathic treatment as could well be imagined; and the fact of its being put in practice, even with impunity, may afford matter for reflection. Cases are detailed by Dr. Engin and others, where scarlatina, erysipelas, herpes, and other cutaneous eruptions, were treated on hydropathic principles, and seemingly with success. Hæmorrhages of various kinds, from nose, lungs, bowels, &c. are subjected to this treatment, as well as a host of chronic maladies, including constipation, hæmorrhoids, amenorrhœa, chlorosis, liver complaints, jaundice, gout, rheumatism, melancholia, hypochondriasis, hysteria, epilepsy, tic douloureux, gastrodynia, scrofula, rickets, &c. Now, although I should be far from recommending this practice in many of the complaints where it has been employed, yet, as the institutions for the hydropathic treatment are now spread all over Germany, and open to the inspection of all medical men, (unlike the hocus-pocus fraud, mystery, and deception of homœopathy,) it would be unwise not to examine into a system which shocks our prejudices rather than runs counter to historical facts and philosophical reasoning.
