468 MAMMOTH AND OTHER REMAINS IN ENDSLEIGH STREET. 



In reply to Mr. Monckton, the Author said that the Hampstead 

 and Highgate Hills would not, in any way, interfere with the out- 

 spreading of this material from a north-western area to the dis- 

 trict referred to in this paper, as the inclination of the surface was 

 more or less gradual from the Hertfordshire Upper Plain to this 

 point. 



The Author had been informed by Mr. H. B. Woodward that in a 

 cutting made, near Wembley Park, for a new railway-station on the 

 Metropolitan extension Hue, 3 miles south-west of Hendon, some 

 Pleistocene mammalian remains were found in October 1890.^ They 

 occurred in the brown clay with ' race,' therefore they had evidently 

 been transported from higher ground. During the present year, at 

 Pinchley, fragments of bone belonging, as the Author believes, to the 

 Mammoth, were found in the lowest gravel. This proves that the 

 animals must have died before any of the Glacial deposits which now 

 occur at Pinchley had accumulated. 



1 [The following are the particulars communicated to the Author by Mr. H. B. 

 Woodward : — In a cutting made near Wembley Park for a new railway-station on 

 the Metropohtan extension line, there was opened up, in October 1890, a deposit 

 consisting mainly of re-constructed London Clay. In this clay there was a band 

 of gravel, about one foot in thickness, having a clayey matrix, and containing 

 flint-pebbles and fragments of septaria. The disposition of the gravel indicated 

 a basin-shaped arrangement of the deposit, but it is possible that the accumu- 

 lation may have been disturbed by local slipping of the strata. The section 

 showed altogether about 10 feet of clay with the gravel band near the base, and 

 remains of Hippopotamus, &c., were obtained from the gravel and also from the 

 portions of clay exposed just beneath it. The deposit occurs on the slope of a 

 hill, in the higher portion of the Brent Valley, away from the main stream.]
