344 Annual Report of the Consulting Chemist for 1881. 
taining the mixture to stand at rest for a short time, the oil of 
turpentine separated, and formed on the surface of the liquid an 
oily layer of about half an inch in depth. 
Oil of turpentine, in conjunction with ammonia, is employed 
externally in the treatment of inflammation • of the bowels or 
lungs. It is a rubefacient, like ammonia, and, as far as I know, 
is not given internally to horses to cure coughs. 
When oil of turpentine is administered internally, for instance 
as a vermifuge, it is always given dissolved in linseed, or some 
other bland or aperient oil, or in the state of emulsion. 
When liquor ammonice is given internally in certain disorders, 
half an ounce to one ounce is a proper dose, diluted with 20 to 
30 ounces of water or cold gruel, or other mucilaginous diluents. 
In the mixture examined by me, the liquor ammoniac was only 
diluted with four parts of other liquids, and such strong 
ammonia, quite apart from the oil of turpentine, must have 
acted as a strong rubefacient or vesicant. There can therefore 
be no doubt that the mixture, merely diluted with a little gruel, 
when poured down the horse's throat must have caused intense 
pain to the poor animal, and have blistered the throat and 
partially removed the mucous membranes. 
Composition of Fat Ball reported to have been found in the 
Stomach of a Cow. — Last June I received from a member of the 
Society a peculiar fatty substance, in which I found in 100 parts : — 
Fatty acids (soluble in alcohol) 46 "60 
Neutral fats (insoluble in alcohol) .. .. 37'65 
Membranous matter 8 '15 
Phosphate of lime '90 
Carbonate of lime, magnesia, &c 1 • 20 
Alkaline salts 1 • 40 
Sand 4-10 
100-00 
This curious substance, I was informed, was found in the 
stomach of a calf that died ; it was a solid ball about 5 inches 
in diameter. My informant adds : " We have lost a cow, a 
horse, two young beasts, and three sheep ; all died in the same 
way within a few weeks."
