Abstract
MR. MELVIN is at fault in assuming that my paper on sand was “an attempt to distinguish by the aid of the microscope whether sand had been formed by the action of wind or of surf.” Its primary object was to show that chalk-flint had scarcely any place in its formation; but few particles of it appearing even from the midst of rolled shingle whether that be ancient or modern. Other problems of course may be determined or solutions suggested by an extensive examination of ancient deposits, compared with those now forming. I have shown that quartz is he great staple of “sand.” The size of its particles, whether rounded by attrition or flat, rough, and angular, must be accounted for by observing the conditions under which it exists in modern formations. A large series is being examined by me, and a record will be made of the result. As yet I have no theory whatever. I simply record facts.
