of Tropical Leguminosae insert in the xxv vol. of the TransacHom of 

 the Linnean Society, published the Angola Leguminosae, which he both 

 describes and illustrates. Professor Oliver undertook the Lentibulariae of 

 the same region, Reicíienbach the Orchideae, Seemann the Bignoniaceae 

 and the Hederaceae, Miiller the Euphorbiaceae, Schott the Aroideae, 

 HegelmaiertheLemnaceae, Alph. DecandoUe the Campanulaceae, B. Hiera 

 lhe Ebenaceae, Caspary the Nymphaceae, Alex. Braun the Characeae, 

 Munro the single Bambusacea of Angola, AV. Hooker the Ferns, Diiby 

 the Mosses, F. Carrie the Fungi, and Dr. Hooker in a richly illustrated 

 monography that most cnrious Gnetacea of the African continent, called 

 by him WelwUschia mirabilis. A more detailed enumeration of ali these 

 pubhcations which so muchadvanced the knowledge of the Angola Flora, 

 was given by iis to Portnguese readers in the Journal of the Mathema- 

 tical and Physical Sciences of Lisbon n." xiv, 1873. 



In the second year of his stay at London Dr. Welwitsch reported 

 to the Government upon lhe state of the labours he had undertaken, and 

 was oíficially answered on the 28.^^ of Dec. 1864, that the manner 

 in which he had condiicted the matler was honourable both to himself 

 and the Government; bnt at the same lime he was told that it was 

 necessary to have as soon as possible in the Portnguese sclentific es- 

 tablishments the collection of ali the Angola products, as well as the 

 publication which was to make them known in Portugal; in order, as 

 it was added, lo jostify before the Cortes and before the public lhe ex- 

 penses of the whole expcdition, and avoid any interruption in the allow- 

 ance of such that were as yet to be made (doe. n.° 10). Again on the 

 20'^^ of Dec. 1865 an oíScial despatch from the Government ordered 

 Dr. Welwitsch's return to Lisbon, leaving to the care of the naturalists 

 charged with the study of the Angolan collections, Ihose paris of it which 

 had been commilled to them for this purpose. These orders tended to 

 avoid the greater outlay occasioned by the prolonged stay of Dr. Wel- 

 witsch at London, as it was thoughl possible to continue the study of 

 the collections by an intercourse with the foreign naturalists that were 

 to help him. Not having complied with these, nor, as the Government 

 thoughl, with other instructions, as accurately at least as he ought, his 

 salary was stopped on lhe 16.'^ of Feb. 1866. From the beginning of 

 that month ali official intercourse with him remained suspended. 



From the departure of Dr. Welwitsch for Angola at the end of 

 1853 till the time at which his official relations wilh the Governmenl were 

 thus stopped, twelve years passed away. Of these eight were passed in 

 Angola, three in London and one in Lisbon. During this whole period
