Itlas been remarked in Fog and more particularly

(synonyme, grape sugar glucose is suspected, it can
besdttected by not very complicated process. Cane
sugar when boiled in solution OF potasb gives
liquid of browpth color If potato sugar present,
it will give the liquid decided black tint. Cane sugar
fuses at a heat Of 300, and assumes dark brown
color Immediately, forming the cooring matter cal cd
caramel. Grape. or potato sugar, when heated to
300, bos and gives off one tenth of its weight Of
water and then concretes, in cooling into bright yell

Cane sugar combines with the akales and forms, in
bases Of definite proportlonsi275 parts by weight of
sugar, and 1850 parts of lime-a compound from
which the sugar can be re-obained, without having
undergone the least alteration grape starch suss
also combines with the alkales, but cannot again be

In Paris years ago. this adulteraon of confec.
tonery had reached such hight that it becsme ne
cessary fol the Project of Police to publish order
tupprearg the spurious articles; and we think that
the time has come for just such ordinance in this
city.
The report to the Project at that time declares that
q colorng matter derived fru mineral substances
cept oxides of feirugnous lakes and Pus-i bds
should be prohibited. Gamboge too should be
"verey prescribed as being drastic cathari, which,
even in minute doses, necessarily occasions violent
Intestinal irritation. Litmus should also be prohibited
"beoause it is occasionally incorporated with putrsfsd

The papers also used for wrapping up confectionery
should be colored because they often contsin

children using the confectionery.
