from India, by Schlagintweit, Duthie, Clarke, and Beddome; from 

 Gwalior, by Maries ; from Penang, by Curtis ; from Burmali, by 

 Ridley ; from Malaya, by King; from Western China, by Henry and 

 Pratt ; from South Africa, by MacOwan ; from Madagascar, by 

 Scott Elliot; from Australia, by Fitzgerald; from Canada, by 

 Macoun ; from Mexico, by Pringle ; from the West Indies, by 

 Kamage ; from Grenada, by Sherring ; from New Granada, by 

 Triana ; and from Chili, by Borchers ; and of plants of various 

 Natural Orders from the Herbaria of Auerswald, Shuttleworth, 

 Miers, and Hance. 



In the progress of incorporating these additions in the Her- 

 barium the following Natural Orders have been more or less 



t completely revised : 



MyrtacetBj Passijl 



Composites, Ericacem, Myrsinea, Sapotacea, Convolvulacea, Solanacea, 

 Scrophulariacece, Labiates, Orchidea, Liliacea, Cyperacea, Graminea, 



and Filices; together with large groups of Hepatica, Lichenes, Alga, 

 and Fungi. 



Considerable additions and improvements have been made 

 during the year in the exhibition of the specimens and illus- 

 trations of the Natural Orders in the Public Gallery. 



The collections of the fruits and seeds of palms, and of the 

 fruits and seeds of British plants, have been named and arranged. 



The large collection of original drawings made by the late Dr. 

 Schleiden, illustrating the morphology and anatomy of different 

 Natural Orders, have been arranged and mounted, with the view of 

 binding them in volumes for easy reference and preservation. 



The extensive series of slides prepared by, and representing the 

 work of, the late Professor De Bary, lately purchased by the 

 Trustees, has been arranged in systematic order. The medium 

 originally employed in mounting the preparations having been 

 insufficiently secured, every slide has been carefully examined and 

 re-sealed, and, wherever necessary, the specimen has been re- 

 mounted. One-third of the whole collection has been thus treated. 



The typical collection of British Diatomacece belonging to William 

 Smith, and illustrating his standard work on these plants, contained 

 a considerable quantity of unmounted material, which was specified 

 in the published Catalogue. This has all been prepared and 

 mounted on slides, so as to permit of the exact study of the 

 specimens without injury. 



The principal additions to the Herbarium during the year have 

 been (1) the study set of the plants of New Granada formed by the 

 late M. J. J. Triana, consisting of the whole of the plants, so far as 

 collected by himself, which have been described in his works, and 

 m his unfinished "Prodromus Florae Novae Granatensis " ; the 

 collection consists of over 8000 specimens belonging to 4490 species 

 of a flora very imperfectly represented m the Herbarium; (2) the 

 collections made by Aug. Borchers in Atacama, in Northern Chili, 

 consisting of 1100 specimens determined by Professor Philippi ; 

 (d) the extensive collection of North American Cryptogams formed 

 by the late Mr. Eavenel, consisting of more than 14,550 specimens, 

 and including all the species which were described from his 

 materials by Berkeley and others.
