62 EXTINCT BRITISH ANIMALS. 
This animal was one of the earliest arrivals on 
British soil after the ice and snow of the glacial 
epoch began to disappear, and it is in caverns and 
river gravels and sands of post-glacial age that we 
first meet with its remains. Its abundance in 
British deposits of this date is very remarkable. 
Professor Boyd Dawkins has found portions of its 
bones and horns in no less than thirteen out of 
twenty-one caverns examined by him, while the Red- 
deer was only found in seven ; thus, contrary to what 
is generally assumed to be the case, the Reindeer 
predominated in numbers over the Red-deer at the 
time the British bone caverns were being filled. 
In the post-glacial river deposits the same numeri- 
cal preponderance of the Reindeer is observed. It 
has been found in the gravels of Brentford, in a 
railway cutting at Kew Bridge, and higher up the 
Thames in a gravel bed at Windsor, where, in the 
spring of 1867, numerous remains were discovered. 
On visiting the spot with the discoverer, Capt. 
Luard, R.E., Professor Boyd Dawkins found that 
more than one-half of the remains belonged to the 
Reindeer, the rest to Bisons, Horses, Wolves, and 
Bears. They had evidently been swept down by 
the current from some point higher up the stream.” 
In illustration of this accumulation he quotes a 
parallel case from the observations of Admiral Von 
Wrangel in Siberia, who remarks :+—‘‘ The migrating

1840, p. 190. The obviously exaggerated figures must be taken to 
represent the vast numbers of the animals.
