STROPHANTHINFMo 
Stroplianthiii. 
A g'lucoside or mixture of glucosides, obtained from Strophanthus. 
Character. — A white or faintly 3 "ellowish crystalline powder, con- 
taining varying amounts of water of ciwstallization. Permanent in 
the air. Taste intensely bitter; great caution should be used in 
tasting it. 
Solubility. — Very soluble in water and diluted alcohol. 
Dose. — “Average dose: 0.0003 Gm. =0.3 milligramme grain).” 
(U. S. P.) 
Caution. — Keep in well stoppered amber colored bottles. Its solu- 
tions are veiw liable to decompose and should be freshK prepared. 
Exceedingly powerful poison. There is no known chemical assa}" for 
this drug* and, as it is liable to variation, physicians would do well to 
secure specimens which have been tested physiologically. 
STRYCHNINE NITRAS. 
Strycliiiiiie Nitrate. 
C,iH,,N,0,.HN03 
Character.— Colorless, glistening needles, odorless, and having an 
intensely bitter taste; permanent in the air. 
Solubility. — Soluble in water (1:42), alcohol (1:120), and glvcerin 
(1:60); much more soluble in warm water or alcohol. 
The b}"drochloride (the onh^ strvchnine salt official in the Br. P.) 
and the Sulphate (already official in the U. S. P.) both contain water 
of crvstallization and effloresce in dry air. The Nitrate (the only salt 
official in the P. G.) contains no water of cr^^stallization and is perma- 
nent in the air. 
Dose. — “Average dose: 0.001 Gm.=l milligramme (Pj grain).”

SULPHONETHYLMETHANUM. 
Siilphoiietli) Imetliaiie. 
( Trional. ) 
(CH3)(VH3)C(S0AH5)2 
This substance is commonl v known bv the trade name, trional. It is 
official in the German Pharmacopceia under the name Metlndsulfona- 
lum; in the French and Swedish Pharmacopoeias it is called Trional, 
and in the Austrian Phai-macopmia, Trionalum. It should not be con- 
fused with Sulphonmethanum (q. v.) {s^il phonal). 
Chemistry. — Chemicallv it is diethylsulphonemeth^dethyhnethane 
^ regarded as methane (CHJ in 
which two hydrogen atoms are replaced by eth}dsulphone (SOoCgHg)
