1746. BOTTLE, Specific Gravity. Schumann's, for cement, with tube graduated to 50 ce in i/J cc 



divisions $2.75 



1748. BOTTLE, Specific Gravity, Sprengel's, with ground on suction tube, and ground caps. Height 



over all, about 100 mm; diameter of tubes, 14 mm 1.50 



1750. BOTTLE, Specific Gravity, Walker's, for very fluid liquids, as described in Bulletin 109 of the 



Bureau of Chemistry, United States Department of Agriculture, Capacity, about 20 cc. 2.00 



1752. BOTTLE, Specific Gravity, Walker's, same as Xo. 1750, for very viscous liquids. Capacity, 



about 30 cc 2.50 



1754. SPECIFIC GRAVITY BOTTLE, Weld's Precision. For the precise determination of the density 

 of liquids and salt solutions as designed by Prof. Leroy D. Weld of Coe College. With 

 ground-on cap and pointed stopper. Especially valuable for use with highly volatile liquids 

 since the ground-on cap prevents evaporation. The pointed stopper prevents the formation 

 of an overflow drop. With this bottle weighings can be made to an accuracy of 1/1000 of 1 

 per cent., or with twice the accuracy of those made with a flat stoppered bottle similarly 



capped. Capacity, about 25 cc 2.25
