Natural aperient bitter waters

Abstract

The figures of the specific gravity above 1,000 very nearly representing the sum of the magnesium and sodium sulphates per 1,000 parts of the water. Thus in sample A a specific gravity of 1031.1 corresponds to 81.7 parts 9f the snlphates per 1,000 of the water.

Retention of Glycerol and Glycols by Cellophane and Cotton Cellulose

“…A rough semi-quantitative treatment may be given the surface-covering power of the absorbed glycerol and glycol molecules in terms of the recent deductions regarding the structure of cellulose itself (2, S, [6][7][8][9][12][13][14]. These deductions, based on x-ray examination of native cellulose, are summarized graphically in Figure 2, which is taken from a recent paper by Clark (2).…”
