DISEASES OF THE GENITAL ORGANS. 



the milk by essential oils of aromatic plants (anise, cumin, fennel, 

 etc.) are much better digested. The treatment consists in a change 

 of regimen of the animals and in keeping the dairy vessels perfectly 

 clean. 



2. Flavoring matters. They reach the milk after the ingestion 

 of plants of the Allium genus : yellow garlic (A. ochroleucum or suave- 

 olenSy Jacq.), chivet {A. Schœnoprasum^ L.), etc., or flavored medica- 

 ments : asafœtida, camphor, essence of turpentine, etc. They may 

 also come from the atmosphere (disinfection of the stable or of the 

 dairy with carbolic acid, etc.). Milk placed in a room which has 

 been disinfected by carbolic acid has produced phenomena of phenic 

 poisoning in a dog (Zorn). The experimental researches of Lawson 

 Tait have given similar results. 



3. Yellow, redy and blue coloring matters. Yellow and red coloring 

 matters originate, some from vegetables : carrots, rhubarb, madder, 

 saffron, radish, etc. ; others, from normal or pathological organic 

 products: bile (icterus), blood, pus, etc. In various affections of 

 the mammae we observe a colostrum of the color of egg-yelk. 

 Apart from the blue milk of microbic origin, this coloration may 

 also be communicated to the milk by certain plants : Ox tongue 

 [Anchusa officinalis) field shave-grass, horse-tail or scouring rush 

 {Equisetum arvense), yearly mercurial {Mercurialis annuo), knot- 

 berry (Polygonum aviculare), buckwheat (Sarrasin) (P. fagopyrum), 

 " muscaria à toupet " {Muscari cornosum), flowering rush {Butomus 

 umbellatus), cow- wheat (Melanpyrum arvense), indigo plants, etc. 

 (Hermbstadt). 



4. Medicamentous substances. The following may pass into 

 the milk ; camphor, ether, essence of turpentine, asafœtida, chloro- 

 form, tartar emetic (Gunther, Harms), aloes, arsenic (Hertwig, 

 Spinola, Gerlach, etc.) ; hellebore, belledonna, atropine, henbane, 

 stramonium colchicum (Ratti has observed a cholera-like epidemic 

 after the use of goat's milk containing colchicine), hemlock ; mor- 

 phine (Scherer, Gorup-Besanez) [we have never succeeded in 

 demonstrating the presence of morphine in the milk, even after the 

 administration of quite large doses of this agent], strychnine, 

 senna, salicylic acid, carbolic acid; various salts (sulphate of soda, 

 of magnesia, borax, etc.) ; combinations of bismuth ; salts of lead 

 (Gerlach), of copper (Grognier, Gerlach), zinc and iron ; compounds 

 of mercurials (Klink) and iodoform (according to Lusansky, the 

 simple administration of iodide compounds to the cow would give
