ported. Of the Ficus nitida, Thunb. (an East Indian Fig), there 
are two trees at the quarters of the Commander of the Royal Artil- 
lery : the extent of the branches of the larger one is ninety-four 
feet, that of the two, one hundred and twenty-four; and both (we 
presume standing close together) cover a space of 11,000 square 
feet. The Mammee Tree (Mammea Americana), Abricotier des 
Antilles of the French, here attains a great size: in the garden 
at Halton are two trees, the largest sixteen and a half, and the 
other fifteen feet four inches, in the girth of the trunk four feet 
from the ground. Lastly, we shall only mention the Mahogany 
and the Teak, both introduced trees, and both, as is shown 
by Sir Robert Schomburgk, well worthy of extensive plant- 
ing. The late Sir P. Gibbs, when a young man, planted a seed 
of the Mahogany on the estate of Springhead: it was cut down 
previous to his death, when only fifty years old, and after retaining 
several pieces of the wood for his own use, the remainder of the 
tree was sold for 100/. currency. The late Judge Lucas planted 
a Teak (Tectona grandis) on the estate of Sunbury, in 1799. In 
1803, it was upwards of twenty-five feet high, and five inches in the 
diameter of its trunk at six feet from the ground. In 1831, it 
was blown down by a hurricane, and still remains in its prostrate 
state, but living and luxuriant ; and in that condition, in 1846, its 
trunk was thirty-four feet in length, and its girth five and a half 
feet, at six feet from the ground.

Of this most important contribution to our knowledge of 
exotic Algæ, we know not if we can pay it a higher compliment 
than by saying it is worthy of the author. All that we have -
