These numbers indicate a change quite analogous to that before seen to obtain 

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

but the salt, as deposited from water, retains an equivalent of the same at 212 c , 

 and is, according to the above analysis — 



while, in the air-dry state, the crystals contain in addition seven atoms, which 

 they readily part with, as these numbers shew : —

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 dissolved. When heated, the dry salt
