Abstract
MR. THOMAS does not state whether his radiolarian oozes are recent or fossil. The two methods which he has employed are primarily intended for the disintegration of fossil earths such as the Barbados material, and as they depend for their efficiency on the disruptive action of crystallisation and the solvent action of alkalis on silica, they are necessarily more drastic in their action than is necessary for the cleaning of recent deposits.
