Mammoth Tooth from a Chalk Fissure in North Lines. — 



In the south of England one is familiar with the fissures in the 

 chalk, which contain mammalian remains ; but hitherto these 

 do n'ot appear to have been noticed in the north. On visiting 

 the well-known chalk quarry at South Ferriby recently, I 

 obtained an elephant's grinder, which had been ' taken from 

 the chalk,' at a considerable depth, towards the west end of the 

 quarry. As it was picked out from amongst loose chalk, its 

 precise depth could not be ascertained, though it certainly 

 could not have come from the upper portion of the quarry. 

 Traces of sand in a very narrow fissure could still be seen at the 

 place where the tooth was taken, and there is no doubt that at 

 some remote period the specimen had been washed into the 

 crevice. The soil had recently been removed from the top of 

 the adjacent chalk, and a large pipe of sand was met with, 

 though its depth cannot be ascertained until the chalk is blasted. 



The grinding surface of the tooth is considerably worn, and 

 evidently belongs to a very old individual. It is quite white 

 and chalky in appearance ; so much so, that the impression the 

 workmen had obtained that it was really found in the soHd 

 chalk is excusable. It measures 6| inches in length by 2| inches 

 across the grinding surface, and is 4J inches in depth. Mr. E. T. 

 Newton, F.R.S., late Palaeontologist to the Geological Survey, 

 has kindly examined it, and has expressed the opinion that it 

 is of the Mammoth {Elephas primigenius) , though the crown 

 is so much worn that it almost reminds one of the older form, 

 namely, Elephas meridionalis. 



Professor W. Boyd Dawkins recently called at the Hull 

 Museum and saw the specimen, and also expressed the opinion 

 that it was a tooth of the mammoth. The specimen is the lower 

 grinder, and fourth milk or first true molar. — T.Sheppard,Hu11,
