central mass, yet this movement must also be with the rotation of the 

 mass, or at right angles to the axis of the earth. This was an important 

 objection which Dr. King would like to place before Mr. Oldham, though 

 he himself was able to fancy how a ' slant ' from this normal direction 

 might be due to the variable thickness and constitution of the crust, or 

 even to the irregular distribution of land and water. 



In reply to Dr. King, the Author said, That he failed to realize 

 the difficulty raised by Dr. King's mathematical friend and his (Dr. 

 King's) proposed method of escaping from it. He did not suppose for a 

 moment that the crust of the earth had so great a mobility over the 

 nucleus as to allow it to rotate on the same axis but at a different rate 

 under the influence of tidal friction, and he could imagine no other 

 agency by which the state of affairs proposed by Dr. King could be 

 brought about. Further, that in the Himalayas we had an extensive 

 tract of country over which, exclusive of unknown ground to the 

 north, the strata had been compressed into J if not J of their original 

 lateral extension, and that so far as we know this seems to have taken 

 place entirely within the tertiary period ; but even allowing a margin for 

 pre-tertiary contortion, the beds had certainly been compressed into \ of 

 their original lateral extension during the tertiary period, or, in other 

 words, allowing a small correction for the contraction of the earth as 

 a whole during that period, the Northern and Southern margins had ap- 

 proached each other during the tertiary period. So that here we have 

 proof of a sliding of the surface crust over the nucleus in a direction 

 at right angles to that declared by Dr. King to be the only one in which 

 it could possibly take place.

4. An incident in the habits of the Semnopithecus Entellus, the 

 common Hanuman Monkey. — By T. H. Hughes, Esq., A. R. S. M., 

 F. G. S. 



In Jerdon's book of mammals, reference is made to the seasonal 

 quarrels of Semnopithecus entellus, and the account given in the Bengal 

 Sporting Magazine for August, 1836. It is a story of the stronger sex 

 trying conclusions amongst themselves for the charms of the gentler 

 one. The males are exclusively the combatants, and the strongest usurps 

 the sole office of perpetuating his species through the reciprocal agency 

 of his female associates. 



The correspondent of the Bengal Sporting Magazine testifies, that 

 only one adult male is found with each pack of " Hanumans ;" and states 

 that "at a particular season of the year the great body of he-monkies, 

 which had been leading a monastic life deep in the woods, sally forth to
