roots soon become spongy and rotten, and the plant becomes a prey to lichens 
and fungi, and finally dies. The cause of the disease being the humidity of the 
soil, it can only be prevented by planting the tree on soil sufficiently dry, either 
naturally or by drainage. Two parasitic species of Fingus are found upon 
the leaves: Xylomaaceérinum Pers., described and figured in the Encyclopedia 
of Plants, No. 16490., and Erineum acérinum Pers., described and figured 
in the Encyclopedia of Plants, No. 16593. A sweet clammy matter exudes 
from the foliage, and is fed upon by insects, whose excrements tend to dis- 
colour it ; which shows, in some seasons, considerable discolouration and want 
of cleanness and freshness, that may be referred in part to this cause, and may 
be in part referable to particles of dust and other matter floating in the atmo- 
sphere, and falling on the clammy surface of the foliage. 
Statistics. There are a great many fine specimens of this tree in different parts of Europe ; and, as 
it isa well-known species, we shall only select a few, as in other cases, partly to show the rate of 
growth, and partly to show the magnitude attained relatively to time.

and 17 ft. high; in Lancashire, at Lancaster, in the Friends’ Burying Ground, several fine trees 
about a century old, between 60 ft and 70 ft. high, with trunks from 22 ft. to 3 ft. in diameter, and 
heads 60ft. to 70 ft in diameter; at Latham House, 40 years planted, and 45 ft. high; at Aldcliff 
Hall, 50 ft. high, diameter of the trunk 40 ft, and of the head 60 ft.; in Northumberland, at Wool-

planted, and 40 ft. high ; in Warwickshire, at Coombe Abbey, A. P. variegata, 60 years planted, and

A. Pseiido-Platanus in Scotland. In Mid-Lothian, at Hopeton House, 50 ft. high, the trunk 4 ft. 
10 in. in diameter, and the diameter of the space covered by the branches 90 ft.; at Moredun Park 
are two trees 50 ft. high and 70 ft. high, the trunks 3 ft. 3 in. and 4 ft. Gin. in diameter, and the 
heads from 50 ft. to 60 ft. in diameter; at Calder House, one standing on the pleasure-ground 
on the road from the house to the church,measured, on the 4th of October, 1799, 17 ft. 7 in. 
in girt, and at the ground 20ft.3in. Its trunk was 12ft. high, with a clear bole, after which it 
divided into five great arms. Its branches extended in diameter about 60ft. This tree is 
known to have been planted before the Reformation; and it is supposed to be not less than 300 
years old; yet it has the appearance of being perfectly sound. It was the tree to which, long ago, the 
iron jugs (a species of pillory) were fastened. The tree came gradually to grow over them; and they 
have now been completely enclosed in its trunk for a considerable time. At the place where they are 
enclosed, there is a great protuberance, on the south side of the tree, at the height of between 4 ft. 
and 5 ft.” (Lauder’s Gilpin, i. 272.) At Preston Hall, there isa tree, 19 ft. Sin. in circumference, at
