facilities required. Thus it would be of great use, and I, for my 

 own part, should feel particularly obliged if any of your corre- 

 spondents in different parts of the country could furnish us with 

 information on this point. I would confine myself more especi- 

 ally to the occurrence of the bones of elephants (the teeth and 

 tusks being so easily recognised), although, at the same time, any 

 information respecting the bones of other animals would be very 

 acceptable ; and I would ask for a mention of their occurrence 

 naming place, character of deposit, depth beneath the surface, 

 position, whether in valley or on hill, &c. Such information you 

 might tabulate monthly or quarterly, mentioning the authority. 

 Or what would form a still more valuable record would be, that 

 resident correspondents should each take a county, and give a 

 list of places where such remains are or have been found. We 

 particularly require information in this respect with reference to 

 Northumberland, Lancashire, Cumberland, Cheshire, and other 

 northern counties, although in the more southern counties the 

 same particulars are also in many cases equally required. An 

 additional interest now attaches to this subject, from the circum- 

 stance that there are indications of each different stage of this 

 Pleistocene period having been marked by different species of 

 elephant, &c. If these can be distinguished by the aid of Dr 

 Falconer's forthcoming paper in the ' Quarterly Journal of the 

 Geological Society,' the information furnished will be the more 

 valuable. I am, sir, yours truly, JOSEPH PKKSTWICH. 



J. Prestwich to H. Falconer. 10 KENT TERRACE, 7/5/58. 



MY DEAR DR FALCONER, I twice had Lartet's paper in my 

 pocket to call on you with it, but was both times prevented by 

 business. I should much like to hear more of your Western 

 progress, and will take an early opportunity to call on you, if 

 possible, before I leave town on Thursday. I shall be at the 

 Koyal Society to-morrow evening. If I do not see you there, I 

 will try to call on you at 5J on Monday. 



I am the more anxious to hear what you have seen in Devon 

 as I am going there shortly, after first a visit to Eouen, Paris, and 

 Brussels, and intend to visit Banwell and a few other places I 

 have not yet seen.
