 tissue. Also the fatty 

 substance forming the 

 acid principle of biliary 

 calculi. It is a glitter-

 touch, crystallizing in 

 fine needles and rhom- 

 bic plates. It is quite

Cholin (kol'-iti) [jo/b?, bile], C 5 H 15 N0 2 . A substance

 pig's bile and ox-bile, hence its name. It is also 

 found in the extracts of the suprarenals, and is a pro- 

 duct of the decomposition of lecithin. It is a colorless 

 fluid, of oily consistence, possesses a strong alkaline 

 reaction, and forms with acids very deliquescent salts. 

 It is a very unstable body. It is soluble in alcohol or 

 ether. It is distinct from, though closely related to, 

 neurin. C. Group of Ptomaines, four ptomaines — 

 Cholin, Neurin, Betain, and Muscarin — have been thus 

 classified. All these bases may be considered as oxida- 

 tion-products of trimethyl-ethyl-ammonium hydrate.
