BURG has given in a complete form the results of his researches 
upon the naturally ocourring euakorme alkaloids These bodies 
are three in number: Ist, Atropine C,,H,,.NO 
tropic acid C,H,,0,, and tropine C,H,,NO. 2d, Hyoscyamine, 
C,,H,,NO,, oceurring in Atropa belladonna, Datura stramoniun, 
yocyamus niger, and Duboisia myoporoides, and splitting also 
into tropic acid ©,H,O, and tropine O,H,,NO. 3d, Hyoscin, 
C, (A, NO, occurring in Hyo yoscyamus niger, and splitting into 
tropic acid C,H,,O, and pseudo-tropine C.H,,NO. It appears the 
that the mydriatic ‘Alkaloids occurring in nature are only three in 
number and that they os all isomeric with one another. Mewnnd 8

‘On the Synthesis of Tropie acid.—SrixGe. has effected a 
new w synthesis of tropic acid by acting on acetophenone with hy- 
drocyanic acid, producing the cyanhydrin of acetophenone. 
d's his heated to 130° with strong hydrochloric acid gives ey 
dratropic acid. By the action of soda on this for a sbort tim 
atropic acid is produced, and for a longer time tropic acid. oO
