products of the Portuguese section (in which will be found a great 
amount of previously unpublished matter), he has lived cons ly in 
London, alone and absorbed in his work, in spite of ill-health sufficient 
to have caused most men to seek rest and quiet. It was not, however,

Besides the memoirs and papers — mentioned on African 
Botany, Dr. Welwitsch, since his residence in London, oe 
several others, the most important of per seci is the Sertum Angolense 
in the ‘‘ Trans. Linn. Soc.,” vol. xxvii. (1869), with twenty-five plates 
by Fitch. In this i communication a number of the most 
re carefully and fully de 
genera are founded, sad iotuaigtt new species, and in the introduc- 
tion is a succinct account (in Latin) of the geography and climate of 
nna ona and Benguela. 
There are also two papers in the ‘‘ Journal of the Linn. Soc.,’’ ‘ On 
Scomaicuble Species of Cissus from the South of Benguela, &e., &e.”” 
Viii., p.- , and ‘Observations on the and Geographical 
Distribution of Gum Copal in Angola” (ix., p. 287), and a antl on 
can Loranthacee in the ‘‘ Gardener’s Chronicle’? for July 1st, 
1871. In conjunction with Mr. Currey he published the first part of 
Fungi Angolenses (Trans. Linn. Soc., vol. xxvi., p. 279), containing a 
number of new species.

the Lichens in the “ Bull. Soc. "Linnéenne de Normandie” for 1869.
