was obtained after an exclusive flesh diet of twelve and twenty-seven 
days. The milk had an acid reaction at the moment it was taken from 
the teat, and was were oa by heat. The author considers 
that the acidity of the milk was due to the presence of an acid phos- 
phate of lime, which in < eet process for examination changes 
the sugar of milk into glucose during the evaporation. In his enpae- 
ments the whey was evaporated with carbonate of magnesia 
concentrated alone, no crystals could be obtained, but the anid gave 
evidence of the presence of glucose by reducing the salts of copper in 
the presence of potas + eh

—M. Henneysere has found that the blood of fowls contains silicate of 
soda or potash, which explains the fact previously observed by M. 
Gorup-Besanez, that their feathers contain a large amount <2 et

eral Waters ; (Chem. Gazette, Feb., spt p. 54, and Ann. der Chem. 
und Pharm., t. Ixi, p. 219. —M., Tripiz sometime since detected arsenic 
present in various ores of iron, as the hydrated oxyd, sparry iron ore, 
and the argillaceous and bog ores which may be regarded as deposits 
ined for these metals in the ordinary manner. In t way he 
amined the sediments of the chalybeate waters of Gsiesbach, Rippol 
sau, Tienach, Rothenfels, and Cannstadt, as also the hot spri 
Wiesbaden and the effervescent waters of Ems, Pyrmont, pas 4 
and Brohl; arsenic and copper were found in all of these, and anti- 
mony in that of Wiesbaden. M. Figuer has confirmed these results 
with the water of Wiesbaden; 100 een of it contain about 0:045

in the 11 litres of the Wiesbaden water. It probably exists as an ar- 
senite of soda, but when the iron in the water becomes per-oxy it 
combines with the acid and is deposited asan arsenite of iron.
