82 BIOGRAPHICAL NOTES ON THE EARLY BOTANISTS 



Catalogue of the Royal Society. Alphonse De Candolle 

 named after him the genus Winchia in Apocynese, ^^ Nomen 

 in honorem clar. N. _^. Winch, qui de geographia. botaniccs 

 optime disseniit." He acted from 1816 to 1838 as secretary 

 of the Newcastle Infirmary. His herbarium, which contains 

 20,000 specimens, is now at the Newcastle Museum. 



John Vaughan Thompson, Surgeon to the 37th Regiment, 

 published in 1807 a catalogue of plants growing in the vicinity 

 of Berwick-on-Tweed (132 pages, 8vo). It is arranged after 

 the Linnean system, and includes a small number of Crypto- 

 gamia. It is often cited in Winch's Flora. Dr. Thompson 

 also collected in Jamaica and Madagascar. Robert Brown 

 named after him the genus Tho??ipsonia in Passifloreae, which 

 by Bentham and Hooker is reduced to Deidamia, Thouiars. 



John Thornhill and John Thornhill, Jun., are occasion- 

 ally cited as the authorities for stations near Newcastle, both 

 in Winch's "Botanists' Guide" and "Flora." The elder 

 Thornhill signs the preface of the former in company with 

 Winch and Waugh, and united with them in 1806 in pre- 

 paring a type herbarium for the Literary and Philosophical 

 Society. The younger Thornhill was for many years librarian 

 to this Society, and lectured on botany at the Newcastle 

 School of Medicine. Wilson named a Phascum collected near 

 Newcastle in 1841 P. Thornhillii, but afterwards reduced it to 

 a variety of P. biyoides. In Dixon and Jameson's Handbook 

 it stands as Pottia bryoides var. Thornhillii, Brathio. 



Richard Waugh died 1806. Of this botanist I know very 

 little. He united with Winch and Thornhill in the " Botanists' 

 Guide" of 1805, but died before the second volume was 

 published in 1807. He stands as the authority for very few 

 localities. 



James Backhouse, born 1794, died i?69, in early life Hved 

 at Darlington, from which neighbourhood a few localities 

 are given on his authority in Winch's " Flora." He was 

 apprenticed to a chemist, but his health broke down with the 

 confinement, and he became, in partnership with his brother,
