great progress has been made towards the complete arrangement of 
the collection. 
“‘ Last autumn, the cabinets and their contents, with the exception 
of those containing the British plants, were removed to a commodious 
room in the new Museum at the Botanic Garden. 
“The Society’s collection of British plants, which still remains in 
the Society’s rooms at the University, is now, by the labours of Mr. 
Lawson, in a most perfect state, and will prove a valuable aid to those 
who may be studying critical species, or the geographical distribution 
of plants in the British Isles. |The European herbarium is also in a 
most satisfactory condition, but in consequence of the absence of our 
diligent member, Mr. Blackie, its arrangement is not yet quite per- 
fect. The collection is one of great extent, comprising plants from 
nearly all the countries of Europe. During the last year it has been 
enriched by valuable contributions from Spain and Portugal, and bya 
very complete set of Scandinavian plants, from Professor Blytt, of 
Christiana, one of the Society’s foreign members. ‘The Asiatic por- 
tion of the collection, the most extensive and perhaps the most 
valuable of the whole, is now not far from being finished. This col- 
lection, I have said, is very extensive ; it consists principally of plants 
from the East Indies, with a few from Arabia and Syria, part of the 
collection left to the Society by Mr. Christy. The Indian plants 
have been collected by such illustrious men as Roxburgh, Wallich, 
and Wight, also by the Countess of Dalhousie, Dr. Cleghorn, Captain 
Campbell, and Dr. Jameson, of the Company's Gardens at Saharun- 
pore. By the labours of Dr. Cleghorn and myself, the naming and 
arranging of the species have advanced to the Orchidacee, but still 
much has to be done in the way of revision, &c. The Society’s 
collection is rather rich in African plants, of which a considerable 
number of species is from the Cape of Good Hope, some named, but 
the greater part undetermined. They are nearly all glued down. 
“The Society have also a large and good collection of plants from 
America, principally from North America, contributed by Dr. Gavin 
Watson of Philadelphia, Mr. James M‘Nab, and Dr. Philip Maclagan. 
Some of them are already glued, and the whole collection is ready to 
undergo this process. 
“The number of South American plants (rarities in all herbaria) is 
small. Within the last two years the amount has, however, been 
increased by very valuable parcels from Mr. Spruce, a collector in the 
northern provinces of South America. Since last report a consider-
