Tae New BUILDING ror THE Kew HERBARIUM. — In the August 
number of the Journal of Botany is a part of Sir J. D. Hooker’s Report 
for the Year 1876 of the Herbarium of the Royal Gardens at Kew: 
“The new building for the accommodation of the herbarium is in a very 
advanced state. It will consist of a hall attached to the back of the 
present house. The whole of the latter will be preserved except the 
drawing-room, a single apartment that was added on to its north side, 
and which has been removed to make room for the new hall, which is 
eighty-six feet long by forty feet broad, and contains two galleries ten 
feet broad running round it. The galleries will communicate with each 
other and with the ground-floor by two circular iron staircases placed 
one at each end of the building. On each floor there will be an en- 
trance from the old building closed by double iron fire-proof doors. The 
long sides of the building will be lighted with forty-eight windows, eight 
on each floor on each side. The cabinets for holding the specimens will 
be arranged in blocks eight feet high, of two tiers projecting like buttresses 
between the windows on the ground-floor and galleries, thus accommodat- 
ing the greatest number of cabinets with the least loss of space, a very 
important consideration, considering the extent of the collection and the 
time that would be otherwise lost in consulting it. At the present time 
the number of cabinets is upwards of six hundred, and the estimated 
number of specimens contained in the whole is now considerably over a 
million, reckoning as one all the individuals of the same plant from the 
same locality.”
