iodide daily caused a considerable decrease of the milk secretion in 

 goats in consequence of a disturbance of the gland function. Alco- 

 hol (up to 100 e.c.) and alcoholic drinks (1-2 liters of beer) pro- 

 duced no change in the quantity of milk secreted by goats, but 

 increased the relative fat content. Morphine, pilocarpine and 

 lead salts had no effect on the quantity or quality of the milk. 

 Salicylic acid appeared to increase somewhat the quantity of milk 

 and the sugar content. Rohrig, in his experiments on goats (Vir- 

 chow's Archiv., Bd. 57), observed no alteration of the milk secre- 

 tion even after very large doses of morphine (up to 1.2). On the 

 other hand, he reports a considerable acceleration in the milk 

 secretion after the administration of jaborandi leaves (pilocarpine), 

 a result which is disputed by other experimenters (Partsch, Heiden- 

 hain) who obtained negative results in similar experiments. After 

 the administration of drugs which increase blood-pressure (strych- 

 nine, caffeine, digitalis), Rohrig observed an increase in the quan- 

 tity of milk, while the amount was decreased when drugs were 

 given which reduce blood-pressure (potassium bromide, chloral 

 hydrate, etc.). According to Feser (Jahresbericht der Miinchener 

 Tierarzneischule, 1885, 1889 and 1890), the milk secretion of healthy 

 cows was slightly increased after the injection of eserine and pilo- 

 carpine; a greater increase occurred in his experiments with eseri- 

 din. Feeding experiments conducted by him, in which the milk 

 of these cows was fed to swine, demonstrated that milk from cows 

 treated xnth eserine could be fed to swine without any disad- 

 vantage whatever. Hess, Schaffer and Bondzynsky (Landw. 

 Jahrb. der Schweiz, 1888) tested the effect of fennel, calamus, 

 anise, caraway, juniper berries and gentian upon the milk secretion 

 of healthy cows and goats and found that even very large doses of 

 these drugs had no real influence upon the quantity or quality of 

 the milk. The drugs mentioned were not perceptible in the milk 

 through any change of taste or odor. Only in the case of fennel, 

 the odor of the drug was observ^ed in an alcohol-ether extract of 

 the milk. Frohner's own experiments (Monatshefte fiir prak- 

 tische Tierheilkunde, 1891) with sodium bicarbonate, sulphur, sul- 

 phurated antimony, juniper berries, atropine and pilocarpine on
