come again except from other animals of tlie same kind. Yards, wbere 

 any of these animals are kept, should be sprinkled with lime and the 

 walls washed with diluted lye, or whitewashed before the animals which 

 have been treated are returned. This will ensure safety from any par- 

 asites which may have fallen to the ground where the goats have Iain. 

 The treatment should be thorough. As these animals are small the 

 best method is to immerse them in tobacco water, thus insuring the de- 

 struction of every parasite and nit, even those on the nose, by immers- 

 ing them while holding the nostrils. If the hair is long on the Angora 

 they should by all means be sheared. If it is not desirable to dip them, 

 the selected remedy may be sopped on the skin and wool and thoroughly 

 rubbed in so as to wet the skin. 



Medicines may be applied in three forms : in powders, as pyrethrum 

 or Persian insect powder, and tobacco dust; in ointments, as oil or lard, 

 with some added ingredient, and in baths, as the tobacco or arsenical 

 dips. Of these the first is the more objectionable and the least valuable. 

 The second is better, but not entirely successful. The third is the one 

 which should be used in the majority of oases, as it is the most certain. 



The following recipes are among those in use, and are recommended 

 by various authorities : 



A decoction of stavesacre seeds, 3 ounces to 2 quarts of water, to be 

 thoroughly rubbed in. (Neumann.) 



A decoction of stavesacre seeds, 1 ounce to 1 quart of water or vine- 

 gar, or half water and half vinegar. (Finlay Dun.) 



In powders, tobacco, pyrethrum, stavesacre and sabadilla may be 

 used, but the last two are not advisable. 



Benzine 1 part, soft soap 6 parts, water 20 parts, or petroleum (kero- 

 seae) 1 part, sweet oil 10 parts. (Neumann.) 



Schlegs' mixture is recommended in Germany for its efficacy and 

 harmlessness when prudently used. Arsenious acid one-half ounce, 

 potash one-half ounce, water 3 pints, vinegar 3 pints. (Ztirn.) 



The most efficacious remedies are the tobacco, or the tobacco and 

 sulphur dips, atJVised for scab. For iiocks of large numbers, nearly all 

 other recipes are unavailable. 



Mercurial salves should not be used. 



Ziirn advises tobacco 1 part, water 20 parts, or water 20 parts and 

 vinegar 10 parts, to be made into a decoction, and vinegar added after 

 cooling. The kerosene emulsion may also prove a valuable remedy. It 

 should be applied as directed for exterminating sheep-ticks, or by meaus 

 of a force-pump and spray -nozzle.

The common goat, Gapra Mrcus, L., is quite commonly infested by a 

 species of louse which has been identified by the writer as Trichodectes
