— the extraction of the fat, light petroleum boiling at 
—45° was used. The fat hasa yellow colour and greasy con- 
sistency ; but on exposure to the air and light the colour dis- 
appears and the fat soon becomes rancid. It hasa specific 
gravity of 0°9175 at 15°, melts at 25°3, solidifies at 17°°-5— 
18°5. It contains sotsidariale quantities of free fatty acids, 
but only asmall amount of glycerol. One gram of the fat 
requires 192°3 mgrms. of KHO for the complete saponification 
of the fatty acids. It is partly soluble in alcohol, and perfectly 
soluble in ether, carbon bisulphide, benzene, &c. The fatty 
-scids obtained by saponifying the fat with potash-ley, and de- 
‘composing the resulting soap by means of a ten per cent. solu- 
o tion of hydrochloric acid, have a white colour, and pleasant 
r and taste. They melt at 39°°5, solidify at 38°, and 
dissolve readily in alcohol. According to Schadler the butter 
consists of 80 per cent. of stearin and 20 per cent. of olein; ve 
hor, — found that it contained — and olein..
