Professor Boyd Dawkins, F.R.S., made some remarks 
with reference to the dates of the introduction of the 
Pheasant and Fallow Deer into England. He stated that 
there were entries of the Monks of Waltham, of allowances 
to the Canons, from which it would appear that the pheasant 
was known as early as A.D. 1050; and from remains found 
in Roman refuse heaps it was probable that the fallow 
deer was introduced during the period of the Roman 
occupation of Britain. 
Mr. Thos. Rogers exhibited specimens of Erinus Alpinus 
from Downliam, near Clitheroe, where the plant is found in 
considerable profusion, especially on the wall of the vicarage 
garden, and made some remarks on the probable naturaliza- 
tion of the plant in England.
