138 Effect of External Influences. 



contains the halogen in the form of a salt, whereas in feeding 

 iodized fats the milk fat contains iodine. 



According to Rosenhaupt and Bucura the same applies to 

 bromine. 



According to Stumpf, Baum and Seeliger, in feeding com- 

 pounds of lead small quantities (0.02%) of this substance pass into 

 the milk. The ingestion of such milk was found harmless for ani- 

 mals. The lead was eliminated for a longer period than the time 

 during which it was fed. Milk which contains salts of lead could 

 produce severe injurious effects if taken for a long time (chronic 

 lead poisoning). 



Feeding of salts of copper results only in the appearance of 

 traces of copper in the milk. 



The feeding of iron preparations does not to any noteworthy 

 extent influence the contents of the milk. 



Mercury may pass into the milk (Bucura) ; likewise arsenic 

 when administered per os or injected in any form subcutaneously 

 (Bucura, Ittalie and Jesionek). 



Substances like aloes, senna leaves, rhubarb and croton may 

 influence the milk in color and taste, and will be partially eliminated 

 with the milk. 



According to Eost and Wiley boracic acid may pass into 

 human milk; likewise after the ingestion of Glauber salts the 

 S0 3 content of the milk is supposed to be increased (Hess and 

 Schaffer). 



According to Baum tartar emetic is not found in the milk of. 

 cows treated with this drug, whereas Harms claims it is eliminated 

 with the milk. 



The feeding of large quantities of alcohol effects a diminution 

 of the specific gravity and an increase of the fat content of the 

 milk. The quantity of the milk appears somewhat increased (in 

 goats). Elimination of alcohol with the milk does not occur. Wel- 

 ler and Teichert proved that alcohol would pass into the milk of 

 cows after feeding them with large quantities of incompletely ex- 

 tracted distillery slops. 



Although Horder and Herdegen claim the secretion of salicylic 

 acid with the milk, Richter, Pauli and Stumpf disclaim its 

 elimination in large amounts. Pauli and Stumpf succeeded in de- 

 tecting small quantities of salicylic acid in the milk of nursing 

 mothers treated with this substance, and also in the urine of their 

 babies, as well as in the milk of experimental goats. In this regard 

 individual peculiarities must also be considered since in one nurs- 

 ing mother the presence of salicylic acid was demonstrated, where- 

 as the examination was negative in another case. 



According to Pinzoni the same applies to antipyrin. Salol 

 does not appear in the milk after its administration. 



Chloroform and ether are found in considerable quantities in 

 the milk after anesthesia (Nicloux).
