DIAGNOSIS.—Unless the distension of the gall-bladder is sufficient to cause a recognizable tumor, gall-stones in that organ do not produce symptoms by which they can be diagnosticated. If sudden attacks of violent pain in the right hypochondrium, accompanied by nausea and vomiting and followed by jaundice, have occurred from time to time, then the presence of biliary concretions may be suspected if the symptoms belonging to them are present in the intervals between the seizures. The migrations of calculi produce symptoms so characteristic that error is hardly possible. The only disorders with which an attack of hepatic colic may be confounded are gastralgia and hepatalgia. As regards the first, the distinction is made by the seat of pain, by the absence of after jaundice, and by the lack of a concretion passed by stool. As the diagnosis may depend on the finding a concretion, the writer must again affirm the importance of a properly-conducted search of all the stools passed for several days after the paroxysm.

Hepatalgia is diagnosticated with great difficulty, for the pain has the same seat, the same character, but as a rule it does not terminate so abruptly, is not accompanied by such severe vomiting and depression, jaundice is absent, and no stone can be found in the evacuations. Both gastralgia and hepatalgia occur in the subjects of neurotic disturbances—in the pale, delicate, and hysterical—whereas, as a rule, hepatic colic happens to the obese, to the persons of active digestion addicted to the pleasures of the table.

The passage of calculi may be confounded with flatulent colic, with the pain caused by lead and other mineral poisons, with impaction, internal strangulation, local peritonitis, and similar causes of sudden and violent pain. The differentiation is made by attention to the seat and character of the pain, by the previous history, and especially by the absence of jaundice and of a concretion. From renal colic the hepatic is separated by the position of the pain, by the direction taken by it, and by the retraction of the testicle, the irritability of the bladder, and the appearance of blood in the urine—all characteristic symptoms of the renal affection.

TREATMENT.—The treatment of biliary concretions includes the remedial management for the calculi in position, for the paroxysms of hepatic colic caused by the migration of these bodies, and for the results and complications.

Treatment of the Calculus State: Of Inspissated Bile.—As the particles of inspissated bile are deposited along the larger hepatic ducts, and form in consequence of a deficiency in the amount of glycocholate and taurocholate of soda, two methods of treatment are to be carried out: free purgation by an active cholagogue to wash out the offending substance, and the exhibition of a soda salt to promote the alkalinity of the bile and the consequent solution of the bile-pigment. Harley's method, which he strongly urges, consists in the administration of "one or two drachms of sulphate of soda in a bitter infusion every morning before breakfast, or from twenty to thirty grains of bicarbonate of soda, along with a drachm of taraxacum-juice in a bitter infusion, every night at bedtime at regulated intervals for a month or so, according to the constitution of the patient and the severity of the symptoms."

As persons who suffer from inspissation of the bile are naturally bilious, it is of the first importance in the prophylactic treatment to regulate the diet. Indulgence in malt liquors, in fatty and saccharine articles of food, must be forbidden. Acid fermentation in the course of duodenal digestion should be prevented by withholding the starches and sugars. Peptonized foods, given with an alkali, are highly useful. Milk, fresh meat, and the succulent vegetables are the proper constituents of a diet for these subjects. Bread is one of the most offending articles, and should be restricted in amount as much as possible.

Next to a suitable diet, systematic exercise is a measure of the highest utility in these cases. A daily morning sponge bath of a weak alkaline water not only maintains the skin in a healthy state, but also promotes the oxidation processes of the body. The alkaline mineral waters of Wisconsin, Michigan, Virginia, and other States, especially of the Bethesda Spring of Wisconsin, may be drunk with great advantage to accomplish the same purpose.

We possess direct means for preventing inspissation of the bile—remedies which act in the physiological way by increasing the proportion of glycocholate and taurocholate of soda. Harley prefers the sulphate and bicarbonate for this purpose, but my experience is in favor of the cholate and phosphate of sodium, especially the latter; for, whilst it plays the part of a soda salt, it exerts a decided cholagogue action, thus effecting the results achieved by the combined use of sulphate of soda and taraxacum. A cure may be confidently looked for in this malady by the persistent use of sodium phosphate—drachm j ter in die. It seems to act more efficiently when given dissolved in hot water.

The paroxysms of hepatic colic due to the passage of inspissated bile are to be treated in the same way as when this condition of things is caused by the migration of formed calculi. The action of cholagogue purgatives is more decidedly beneficial in the attacks due to the passage of inspissated bile.
