O. Leow on Ferocyanid of Potassium, 383 
through 15 or 20 ounces of water, did not dissolve after many 
hours standing. In a mixture of alcohol and ether it dissolves 
as easily as-sugar in water, and in such quantity as to make 
the liquid syrupy. 
Its detonating properties are but slight. If it be well dried 
and a match be applied, it deflagrates with a feeble flash. 
It has been stated by Dr. V. Monckhover, that when dissolved 
in alcohol and kept sometime in a warm place, it undergoes de- 
composition, as evidenced by the fact that the solution then gives 
an abundant precipitate with nitrate of silver, which at first it 
did not do, An experiment made in this direction did not give 
the result thus indicated. A solution of nitroglucose in alco- 
hol, containing about 40 grains to the ounce, was placed in a 
stoppered vial and was kept in the sand bath at a temperature 
of about blood heat for nearly a month. But neither it nor a 
fresh solution gave a precipitate with alcoholic solution of ni- 
trate of silver. It would seem from this that certain condi- 
tions of temperature or otherwise are necessary, in order that 
this decomposition should take place.

solved in alcohol of 90 per cent, with powd ferrocyani 
potassium for 4to6 hours. An action gradually took place, by 
which chlorid of potassium was formed, together with another 
ammonia was developed; after the latter ceased to be evolved, 
the liquid was mixed with
