of his scientific work ; a sum of <£60 was also paid to him on 

 account of any subsidy to which he was entitled. He packed a 

 great part of his herbarium, but had not afterwards suflicient 

 means to undertake the journey to Portugal. 



With the exception of a short visit to Paris in 1867, in connec- 

 tion with the Exhibition there, for which he made contributions 

 for the preparation of the catalogue of the industrial products of 

 the Portuguese section (in which will be found a great amount of 

 previously unpublished matter), Welwitsch resided continuously 

 in London from 1863, alone and devoted to his work, in spite of 

 ill-health and suftering sufficient to have caused most men to seek 

 rest and quiet. He died in London on the 20th October 1872, 

 and was buried on the 24th of the same month in the Kensal 

 Green cemetery. The executors have placed the following 

 inscription on his tomb, surmounted by a Tumhoa (Welwitschia) 

 plant carved in relief : —

FLOR^ ANGOLENSIS INVESTIGATORUM PRINCEPS, 



NAT. IN CARINTHIA, 25 FEB, 1806, 



OB. LONDINI, 20 OCT. 1872. 



The correct date of birth is the 5th (not the 25th) February 

 1806, as is set out in an attested copy, dated Vienna, April 1839, 

 of a certificate dated Maria Saal, the 31st March 1818. 



For the purpose of this biographical sketch free use has been 

 made of the late Dr. Trimen's paper in the Journal of Botany, 

 1871, pp. 111. The portrait prefixed is enlarged from a photo- 

 graph taken August 1865.
