DISPERSAL BY MAN. iS/ 



after a few months not one of either species could be 

 found about the place.^ Specimens were introduced 

 into Scotland " by Pat. Neill, Esq., and placed in his 

 curious and most interesting garden at Cannonmills," 

 but they did not prosper, and, as Dr. Johnston stated 

 in 1830, were believed to be gradually disappearing.' 

 Dr. Lukis tried to introduce the creature into Guernsey 

 but apparently without success.' When put down in 

 the neighbourhood of Christiania, Miss Esmark tells me, 

 it always vanishes after the first year : some trans- 

 planted from Sweden, for instance, all disappeared, as 

 did others brought from Denmark by Professor R. 

 Collett ; probably they were eaten by foxes or hedge- 

 hogs which live everywhere in the neighbourhood.' 

 Professor Collett several times tried to transplant the 

 creature in Denmark, only from one estate to another 

 close by, but it always died. According to the Rev. J. 

 Morton, who wrote in 17 12, many specimens were in- 

 troduced by Lord Hatton into a coppice near his house 

 at Kirby, in Northamptonshire, " with Intentions that 

 they should breed there ; but in a short time they all 

 dy'd." ' Fifty or sixty specimens were once turned out 

 in the neighbourhood of Petersfield, but did not establish 

 themselves ; here, also, as suspected by Mr. Harting,
