present in the mother liquor, and been decomposed by the addition of the hydro- 
chloric acid. The presence of oleic acid in the mother liquor from oleamide may 
be accounted for in a similar manner. 
Palmine. 
Palmine, obtained from castor oil by nitrous acid, when submitted to the 
action of ammonia, behaves in a similar manner to elaidine. A large quantity of 
amide is obtained, which is easily purified by crystallization from alcohol ; and, 
when pure, it closely resembles elaidamide in appearance and properties. 
It commences to fuse at 91°C., is completely fused at 93°C., and solidifies 
at 89° C.

Linseed Oil. 
Linseed oil requires long digestion with ammonia before it is acted upon, and 
it yields only a small quantity of amide, the greater portion of the oil being con- 
verted into a resinous matter, from which it is exceedingly difficult to purify the 
amide. It is insoluble in water, but very soluble in warm alcohol; and is de- 
posited from this solution on cooling in mammillated groups of crystals, which, 
when dry, form a light, bulky, colourless, crystalline substance. The crystals 
soon acquire colour if they have not been thoroughly separated from the resin-
