3l8 VETERINARY HOMCEOPATHY. 



hair stands on end and gives the horse a very ill-favored appear- 

 ance. These parasites may certainly be said to be prolific in their 

 powers of reproduction; after sexual intercourse the female com- 

 mences to burrow under the skin and is said to deposit one egg a 

 day, the meanwhile boring her way under the epidermis; having 

 formed a canal and deposited her ova, she dies; but the numerous 

 eggs she has laid hatch out with the heat of the horse's body in 

 about eight to ten days, and by five weeks these youthful parasites 

 have attained sexual maturity and immediately commence the 

 process of reproduction; from these facts it will be quite clear that 

 only a comparatively short period elapses before a horse is covered 

 with these troublesome guests; and it will also be apparent that if 

 one sexually mature female is left behind after treatment, the 

 whole process will have to be gone over once more, hence the im- 

 perative necessity for thoroughness. The parasites will live for 

 some weeks apart from their natural host, located in brushes, on 

 the sides of stalls and mangers, among harness and clothing, 

 indeed, anywhere or in anything that the original has come in 

 contact with during the period of the attack of the mange; the 

 most diagnostic symptom of the sarcoptic variety is the presence 

 on the neck and shoulders of the semi-circular wrinkles or furrows 

 in the skin. Of course, it goes without saying, that the itching 

 and irritation is intense, provoking the poor horse to rub and 

 gnaw himself continually, and to stamp with his feet; indeed, at 

 times it appears well nigh driven to distraction. 



Treatment of the hor.se itself; thoroughly .saturate the coat 

 from head to tail with the following compound mange dress- 

 ing, not leaving one hair without the application; allow the dress- 

 ing to remain on three whole days and nights, after which the 

 horse must be thoroughly washed with hot water and a non-irri- 

 tating soap that lathers freely, once a day for three successive days. 



Prescription, for mange dressing: Unguent Hydrarg. Fort., 

 one ounce; Ol. Terebinth, eighteen ounces; Ol. Pics, ten ounces; 

 Hellebore Alb. pulv., one ounce; Sulphur Flav. pulv., two 

 pounds; Bolarmenia, two ounces; dissolve the Unguent Hydrarg. 

 in the Ol. Terebinth, carefully, and add sufficient Ol. Uini to 

 make up to seven pounds. This quantity is about sufficient for 

 dressing one full-sized draught horse. The dressing should be 

 constantly shaken while being applied to the patient.
