“...by a rim of limestone cliffs with an escarpment on the landward side. This feature was at first puzzling, since limestone is soluble and softer than the roof of the interior. Its greater resistance to weath- ering, however, seems to be due to its porosity....”

“...of which 71.3 and 78.0% were soluble in acetone. In samples prepared with a trace of copper sulphate, which had become completely tacky and weak, we found even 93 % to be soluble in acetone. The influence of the acetone-soluble constituents on the properties...”

“...During certain months of the year the stem and branches become covered with a semi-transparent greenish gum or lac which is soluble in alkali and is used locally for making soap. About the only use for the wood is for fuel. Normal heartwood absent from specimens;...”

“...held December 12. The following program was presented: 'The Solubility of Mixtures of Sodium Chloride and Sodium Sulphate': A. SEIDELL. The author first gave a brief summary of the status of solubility work in solutions other than very dilute ones, and described...”

“...weathering series approaches this carmine reddish colour. The chemical analyses demonstrated these differences by the percentages of soluble iron, which in the rfbrmal boulder clay is due to limonite and in the boulder clay of the floes probably to the high amount...”

“...action of water, even incomparably much longer than in the case they sink to the sea- bottom ; the effect of depth on the solubility may be neutralized by this circumstance. To this fact must be added that the mixture constitutes a loose material which may...”

“...Seemingly the most obvious source of the silica supplied to the diatoms and utilized by them in forming their tests, is the soluble silica or the hydrous silicates normally contained in sea water. Diatomaceous oozes are forming in certain places in the oceans...”
