LARD 679 



linseed or linseed cake is preferred. For dogs and cats 

 it is useful in protracted cases of distemper, eczema, and 

 other inveterate skin diseases ; in epilepsy, chorea, rickets, 

 and in chronic rheumatism, especially that variety known 

 as kennel lameness, and depending upon bad feeding, faulty 

 nutrition, and damp quarters. 



DOSES, etc. Horses take fgij. ; cattle, fgij. to fgiv. ; 

 sheep, about f j. ; pigs, f3i v - to f i. ; dogs, f3i- to i^iv. ; 

 cats, about f3i. The doses may be repeated twice daily, 

 and persevered with, if required, for weeks ; but if diarrhoea 

 result, they must be reduced or discontinued for a day or 

 two. To remove disagreeable flavour, and prevent nausea 

 or vomiting, it is given mixed with eggs in milk, as an 

 emulsion with mucilage, or in gruel, conjoined with some 

 aromatic, malt extract, or with ether, and is best digested 

 along with or immediately after other food.

ADEPS. ADEPS PBEPARATUS. Axunge. The purified fat 

 of the hog Sus Scrofa. 



To prepare purified lard, the fat from the hog's internal 

 organs is cut into small pieces, triturated in a stone mortar, 

 washed with cold water, drained, melted over a slow fire, 

 strained through flannel or coarse cheese-cloth ; is kept 

 stirred in a steam-heated pan at about 130 Fahr. until 

 it is clear and free from water, strained again through 

 flannel, and preserved in casks, pots, or bladders. When 

 pure, it is white or yellowish-white, granular, neutral to 

 litmus without rancid odour, but with a sweet taste. It 

 melts at about 100 Fahr., forming a clear, transparent 

 fluid, which is a good solvent for wax and resin, and when 

 boiled with alkalies forms soaps. Like other fats and oils, 

 lard is insoluble in water, slightly soluble in alcohol, but 

 perfectly soluble in ether. Exposed to the air, it becomes 

 rancid, and in this state is unfit for emollient purposes. 

 It contains about 62 per cent, of olein and 38 of palmitin 

 and stearin. Distilled water, in which purified lard has 

 been boiled, when cooled and filtered, gives no precipitate
