CAEBON TETKACHLOKID IN FUMIGATION.

Drug Reporter December 1, 1908, were carbon bisulphid 5 to 7 cents 
a pound, and carbon tetrachlorid 9J to 16 cents a pound wholesale. 
These last quotations represent prices in bulk, and variation is evidently 
dependent upon the Quantity desired. 
CONCLUSIONS. 
For all practical purposes it will readily be seen that carbon tetra- 
chlorid at the rate of 28 cents a pound costs fully three or four times 
as much as carbon bisulphid and, in the case of purchase at retail drug 
stores, probably on an average of two to three times as much. Con- 
sidering the strength at which it is to be used, it is very obvious that 
this chemical, unless it can be manufactured at a much lower price, 
can not be as economically employed as a remedy for insects injurious 
to stored products in warehouses, mills, or in any other depository, 
but might be used for choice seeds or in office rooms and dwellings, 
which can be very tightly closed and where the use of inflammable 
materials is prohibited or is for other reasons undesirable.
