Paracresylglucoside, C-Hi0;* O° CsH,* CH;.—Acetochloroglu- 
cose (86 grams), dissolved in absolute alcohol, was added to a 
solution of paracresol (11 grams) and potassium hydroxide 
(6 grams) in alcohol. The mixture, which became yellow, was 
left for 14 hours in ice-water, and then at the ordinary temperature 
fora day. The resulting crystalline magma of potassium chloride 
and the glucoside was diluted with alcohol to 500 c.c., left for two 
days, and then boiled gently for 13 hrs. The filtrate, which smelt 
of acetic ester, left in an evaporating dish at the ordinary tempera- 
ture for a few days, gave a separation of the glucoside in needles 
which, after recrystallization and drying at 100° C., melted at 175- 
177°. Yield 40 per cent. 
0:1737 gave 0°3652 CO:, and 0-1045 H,0,

C,3H,,O0, requires C = 57°77, H = 6°66 per cent. 
[3. p.-cresylglucoside is soluble in alcohol or water, sparingly so 
in acetone, and scarcely soluble in ether, benzene, light petroleum, 
or chloroform. It did not reduce Fehling’s solution before, but: 
readily after, hydrolysis, with emulsin or dilute acids. 
Tetracetyl-(3-p.-cresylglucoside, C,H,;(C2H;0),0;:O-C,H.CH, 
was obtained by heating a mixture of 1 gram paracresylglucoside, 
1 gram sodium acetate, and 4 c.c. acetic anhydride. It was 
recrystallized from absolute alcohol, and, when dried at 105°, 
melted at 119-120° C. 
0°1560 gave 0:3289 CO, and 0:082 H,O, C 57-5, H 5:84. 
Ci: H O10 requires C 57:5, H 5°8. 
It separates from alcohol as long glittering prisms, almost inso- 
luble in water, soluble in benzene, ethylic acetate, ether, and hot 
alcohol. It is visible and multi-coloured between crossed Nicols. 
B Orthocresylglucoside, C,H,0;:O-C;H,:CH;, was obtained 
from a solution of 36°7 grams acetochloroglucose, 5:6 grams potas- 
sium hydroxide, and 10-8 grams orthocresol in about 250 ¢.c. abso- 
lute alcohol. The mixture was allowed to stand three days at the 
temperature of the laboratory, and the yellow solution then heated 
for 13 hours on the water-bath. After filtering off the potassium 
chloride, the alcohol and acetic ester were allowed to evaporate 
spontaneously at the laboratory temperature. The glucoside was
