THE Collection entrusted to us for examination by Sir Aurel Stein consists of samples of sand and fragments of rock, together with a few molluscan shells and minerals.
A list of the localities from which this material was obtained is given at the end of the Appendix (p. 1079) : a number corresponding to each of the specimens described is placed before its appropriate locality, the rocks being distinguished by the numbers from x to 7o and the sands from zoo to 146. Shells are indicated by the letter S and minerals by M.
