Opium—which is said to have been used by Aetius for this disease—or morphia might be used if codeia cannot be obtained, but they are less efficient, more dangerous, and more apt to produce the troublesome symptom of constipation. MacGregor57 gave in one case 60 grains of opium, and in another 90 grains, in the twenty-four hours.

While I have seen the most striking results upon the quantity both of sugar and urine during the administration of codeia, and at the same time have noted a gain in flesh and strength, I cannot say that I have ever seen a case totally recover under its use. Such cases are, however, reported by others. I have always used it in the very worst cases, where dietetic measures had also failed to remove the sugar. As to the mode of action of codeine, we can only speculate. It may be said that it quiets the irritation of the vaso-motor centre, whence result the glycosuria and other symptoms of diabetes.

Next to codeine in efficiency, of drugs, is ergot. The favorable results of its use are more easily explained by its physiological action—contraction upon the muscular walls of blood-vessels—than those of codeine, but it is not so efficient a remedy. It may be used by beginning with half a drachm, and increasing to a drachm, four times a day. Larger doses than this, as much as half an ounce four times a day, have been given, but the stomach rarely permits their continuation for any length of time.

Bromide of potassium, an old remedy for diabetes, has recently been revived and much lauded by the French physicians, but I have never found any results from its use. I can understand, however, how in certain cases of nervous origin it may be useful.

Comparatively recently, Clemens of Frankfort-on-the-Main has recommended the use of what he terms brom-arsen or bromide of arsenic. The dose is one-forty-eighth of a grain three times a day, gradually increased by this same amount until one-sixth or one-fifth of a grain is given daily.58 Clemens, however, unites with its use a dietetic treatment. I have used it in connection with an unselected diet, and have not found the results claimed by Clemens. It is, however, both tonic and sedative, and as such is to be recommended in conjunction with other measures.

58 The late Mr. R. F. Fairthorne, with Mr. James T. Shinn, apothecary, cor. Broad and Spruce streets, Philadelphia, prepared for me a solution of bromide of arsenic in the following manner: 77 grains of metallic arsenic in powder are added in small portions to 240 grains of bromine, the latter being placed in a long test-tube immersed in ice-water to control the otherwise violent reaction. One hundred grains of the tribromide thus obtained are dissolved in sufficient distilled water to make ten fluidounces. One minim will then contain one-forty-eighth of a grain.

Arsenic itself has some reputation in the treatment of diabetes, based upon the observation of Salkowsky that glycogen diminishes in the livers of animals poisoned with arsenic. It is at least a good adjuvant tonic. Leube gave it in diabetes in doses of one-third of a grain three times a day.

Strychnia is also very useful as a tonic, and may be used either alone or in the shape of the sulphate, or combined with arsenic and iron, or it may be given, perhaps preferably, in solution in combination with an acid. Given in combination with phosphoric acid, I believe it the most valuable tonic available in this disease.

To supply the phosphates, in which gluten bread is deficient, as well as for their tonic effect, the various preparations of phosphates are useful. The well-known compound syrup of the phosphates, or Parrish's chemical food, may be considered a type of these preparations. Every fluidrachm, which is a dose, contains 2½ grains of calcium phosphate, 1 grain of ferric phosphate, with fractions of a grain of sodium and potassium phosphate with free phosphoric acid. Similar is the solution of phosphates and phosphoric acid59 known in this country as solution of phosphoric acid with iron, or the latter may be omitted.
