loses the water and so practically regains its normal weight, while the 
antiseptic chemicals remain in the tissue. The result of this is naturally 
deeper impregnation than is the case with the Creosote oils, a point in 
favour of such salts. 
Cost or Treatment. 
Bellit is sold in Austria, in a powdered form at Bl-4 per kilo or 
2*2 lbs., the cost of exporting it to India may be put at R28 per ton. 
The solution used is 1 in 44 or taking a gallon as 10 lbs., the cost of a 
gallon of the dilute solution comes to 2*1 annas, or *013 anna peroz. A 
B. Gr. sleeper contains 3*3 cubic feet or 244 superficial square feet; basing 
our calculations on the amount of absorption as given in the above table, 
the cost of impregnating a B. Gr. sleeper works out as follows :—
