This powder was dissolved in 12 ounces of boiling alcohol. 
The filtered solution being set aside for 18 hours, deposited 
colourless, transparent crystals, consisting of double pyramids. 
These crystals weighed 75 gr. and consisted of morphia in a 
state of purity. The alcoholic solution being evaporated to two 
ounces, deposited one dram of morphia, similar to its state 
before its solution in the alcohol. When still further concen- 
trated, 15 gr. of yellow-coloured morphia were obtained. The 
crystals of morphia thus obtained contained no traces of 
ammonia. 
2. Properties of Morphia.—It crystallizes in double four-sided 
pyramids, whose bases are squares, or rectangles. Sometimes 
in prisms with trapedoizal bases. 
It dissolves in 82 times its weight of boiling water, and the 
solution on cooling deposits regular, colourless, transparent 
crystals. 
It is soluble in 36 times its weight of boiling alcohol, and in 
42 times its weight of cold alcohol of 92°. 
It is soluble in eight times its weight of sulphuric ether. 
Allthese solutions change the infusion of Brazil wood to violet, 
and the tincture of rhubarb to brown. 
They have a bitter and peculiar astringent taste, and the satu- 
rated solutions of morphia in alcohol and ether, when rubbed 
upon the skin, leave ared mark. 
The following are the salts of morphia examined by Choulant. 
(1.) Sulphate of Morphia.—It crystallizes in prisms, dissolves 
in twice its weight of distilled water, and is composed of
