Correspondence — Dr. Murie. 527 



further have alluded to some remarks on the same subject made by 

 Dr. Marsh in a letter to Dr. Pickering, 1841 (see U. S. Expedition, 

 Ungulata, p. 63), also Weiland (Zool. Garten. 1863, p. 255), and 

 Martin (Die Hornbildung bei der Mozama Antilope, ibid, 1864, 

 p. 254), but my former colleague Mr. Bartlett's observations are 

 by far the most conclusive and accurate. Dr. G-ray (Ann. and Mag. 

 Nat. Hist. 1866, p. 326) has given a fair summary of the distinction 

 of structure, etc. of the several kinds of ruminant's horns, which I 

 may call attention to without saying more on the subject. 



At p. 447, instead of "Waterhouse and Hawkins," read "and 

 WaterJiouse- Hawkins ; " the same gentleman who produced the 

 wonderful restorations at the Crystal Palace; the "and" has been 

 accidentally transposed. James Murie.

GLACIAL DRIFT AT FINCHLEY. 

 Mr. H. Walker (of No. 100, Fleet-street, E.G.), addressing the 

 Daily News, October 23rd, writes : — " Not a few Londoners have made 

 a pilgrimage to Muswell Hill during the last fifteen years to see for 

 themselves some tangible relics of the great climatic episode known 

 as the Glacial period which the place is said to exhibit, but to their 

 disappointment they have found the gravel-pits filled up. They 

 may now indemnify themselves by a trip to Finchley Station on the 

 Highgate and Edgware Railway, where the Boulder-clay is now 

 being revealed in a section nearly 30 feet deep. The clay seems to 

 have a maximum thickness of 9 feet, and is rich in fossils drifted 

 hither from the Liassic, Oolitic, and Chalk formations of the north. 

 The railway works are those of the branch line to Barnet. Am- 

 monites are found in great variety and abundance." We will only 

 add to this the additional piece of information, that there exists in 

 the possession of N. T. Wetherell, Esq., F.G.S., of Highgate, the 

 most interesting and extensive series of Boulder-clay fossils from the 

 Drift of Muswell Hill, that have probably ever been assembled by 

 any collector from any one locality, save perhaps that made by the 

 late John Brown, Esq., F.G.S., in the vicinity of Stanway, Essex. 



Professor Morris, F.G.S., of University College, London. — By 

 a grace of the Senate of the University of Cambridge, the venerable 

 Professor Sedgwick (who for upwards of fifty years has occupied the 

 Chair of Geology) has named Professor John Morris, F.G.S., as the 

 Deputy Woodwardian Professor to deliver the usual course of lectures 

 on Geology for the present session, and his choice has received the 

 approval of the Vice-Chancellor and Syndics of the University. 

 Professor Morris will continue to lecture as usual at University 

 College, London. He delivered his first lecture at Cambridge on 

 October 23rd.
