Some Remarks on these Communications. 

The only circumstances leading to fix on the predisposing causes of the Diabetes Mellitus are contained, 

• 1ft. In Doctor Falconer's letter, where a case of the disease is related, as having apparently been produced by excessive indulgence in spruce beer, to reduce corpulency. 

• 2d. In Doctor Cleghorn's first cafe, where the patient had worked hard while under convalescence from fever. 

• 3d. In the cafe of the Gentleman of 77 years of age, who had been addicted to the use of large quantities of sugar.

• 4th. In Doctor Gerard's case, the patient had been subject to pyrosis, and liable to much perspiration previous to the diabetic attack

With respect to the treatment of the disease Doctor Duncan found, in one case, fat meats serviceable. 

Doctor Falconer recommends the mephitic alkaline water; and from the advantage the Gentleman of 77 derived from Schweppe's soda water, it may be of service. There is no doubt it will relieve the acescency of the stomach. We would prefer the soda water, as we think it may act less on the kidneys than that made with the vegetable alkali. 

Doctor Beddoes mentions a cafe where the Bristol water cured the disease. 

Doctor Currie has feen several cases of the disease ; but never saw a case of it with sweet urine cured. 

The Case of Walker shews the effects of the animal food. It was begun on the 29th December, when the daily quantity of clear sweet urine amounted to 13 pounds; on the 31 ft day, being two days only, the quantity of the urine was reduced to 5 pounds, and it had acquired a strong urinous smell. The two Cases, treated at Glasgow, by Doctor Cleghorn, shew also the good effects of the animal food, and of the influence of commotions in the bowels on the quantity of the urine.

The Case of the Gentleman of 77, likewise shews the efficacy of animal food ; but the most striking case is that of Clark, as related by Doctor Gerard. This important case points out, 

First. That in this disease there is no absorption of fluids by the skin. 

Secondly, That animal food may alone, if duly persevered in, cure the disease; and such perseverance may probably be of a very limited duration.
