4 ACTION OF HALOGEN COMPOUNDS OF ETHYL AND AMYL 
above, are given ; the chlorine was determined in a specimen different from either 
of the others :— 
4-505 ee cae dried at 212°, gave 
11°425 carbonic acid, and 
3165 ++ water. 
4-213 +. dried at 212°, gave 
u.4 10-750 ... carbonic acid, and 
2:990 ... water, 
4140 ... dried at 212°, gave 
MI.) 4:345 ++ chloride of silver.

with iodide of ethyl, and it may be expressed thus :—

Strychnine. New Salt. 
but the salt, as deposited from water, retains an equivalent of the same at 212’, 
and is, according to the above analysis— 
C,. H,s N, 0, Cl + HO; 
while, in the air-dry state, the crystals contain in addition seven atoms, which 
they readily part with, as these numbers shew :— 
8-170 crains, air-dry, lost at 212° 
{1.085 s+ water; 
which give a percentage of 12°54; and 12°29 is that required by a loss of seven 
atoms of water in a salt of the formula,—

The hydrated chloride of amylostrychnine crystallizes from water in fine, thick, 
colourless, oblique rhombic prisms, which have a peculiar greasy appearance when 
dry; it is very soluble in alcohol. Its aqueous solution is not affected by dilute 
potass, or by ammonia, except when left long in contact; but is immediately pre- 
cipitated by strong potass, the salt being thrown down unchanged. Oxide of silver 
eliminates the chlorine, leaving the base dissclved. When heated, the dry salt
