MANGE. 



ment is repeated till cured. Cases of medium gravity require from 

 three to four frictions. 



3. Creosote, mixed with olive, or rape oil (1:10-15). It may 

 cure an old generalized mange within a mouth. It is the most 

 efficient agent, but, unhappily, also the most dangerous. The rules 

 applying to its use are the same as for cresol. 



4. Carbolic acid in the shape of carbolated oil at 2-5 per cent., 

 or carbolated glycerin. When these preparations are used it is 

 proper to make the frictions at quite long intervals (carbolic acid 

 poisoning). During the period of treatment it is prudent to give 

 every day a small dose of an alkaline sulphate : sulphate of soda^ 

 2 to 5 grammes — producing a formation of sulpho-phenate of soda 

 in the blood, which is harmless. 



Among other useful substances we may also recommend balsam 

 of Peru (especially in the case of delicate animals and in places 

 where mange is localized in the neighborhood of the eyes), styrax, 

 benzol, naphthol,^ oxynaphthalin, and ichthyol (Rabe, Fried- 

 berger).^ Naphthalin has not given more good results at the Berlin 

 clinic than at Dresden, and it has the disadvantage of spreading 

 a very disagreeable odor. Concerning balsam of Tolu, its action 

 is most uncertain (Siedamgrotzky). Benzine and petroleum has 

 not given us any success. 



Dietetic care is necessary during the whole course of the treat- 

 ment. 



Symbiotes of the dog. The acarus discovered by Hering in 

 1836 and designated Sarcoptes Cyanotis by this author, is a sym- 

 biote which is found in the product of external otitis of the dog 

 [auricular catarrh). It is not certain that this acarus is the cause 



^ The use of naphthol in the therapeutics of cutaneous diseases, parasitic and other- 

 wise, has been studied by A. Josias and ISTocard. If associated with lard, or vaseline 

 (4 per cent.), or oil (10 per cent.), this agent has shown itself of much value in the 

 treatment of dermatoses of our animals, especially in sarcoptic mange, in chronic 

 forms of eczema, and in auricular catarrh of the dog. (See Recueil Vet., 1885.)

2 " Trasbot's charge " (see Sarcoptic Mange of the Horse) is also a very efficient 

 preparation. After having cut the hair and cleansed the skin we use the pure charge, 

 or add an equal quantity of benzine to it. It is applied first on one-half of the body,, 

 and forty-eight hours later upon the remaining portion. After a few days a general 

 soaping should be given with lukewarm water. If mange persists in some places, 

 another application of the charge is made. During the wbole duration of the treat- 

 ment we give internally 2 to 5 grammes of bicarbonate of soda, according to the size- 

 of the animal. — n. d. t.
