respondence with the relatives just enumerated^ from his 
occasional visits to most of them, and from the return of 
those visits to himself, (for his house, although that of a 
bachelor, was always open to his family and friends,) he 
must, in his latter years, have felt this want much less 
sensibly than at the period when it was noted as an apology 
for the slender progress which he then conceived himself 
to have made in the science. Few men have had the good 
fortune to possess so many near connexions engaged in 
pursuits so congenial with their own. 
Thomas Pennant, the correspondent for many years of Gil- 
bert White and the esteemed friend to whom the first series 
of his Letters on the Natural History of his native place were 
addressed, was among the most active of the scientific and 
literary characters of his day. At the commencement of 
his correspondence with White, he was busily engaged in 
the preparation of the octavo edition of his British Zoology: 
the first edition of that work had preceded it but a few 
years ; and it was quickly followed by others ; and by other 
works on zoology, and on antiquities, and by tours, topo- 
graphies, and other productions ; all of which were deser- 
vedly popular. For more than forty years his pen was 
never idle. Industrious himself, he was the cause also of 
industry in others ; and the enumeration which he gives of 
the services he did to the professors of the art of engraving 
by the multitude of plates executed by them for his several 
works, while it furnishes a list of the principal of his pro- 
ductions, will also afford some idea of the extent and variety 
of his labours.
