deprived of their trunk and leaves, and which only receive liquid nourishment 

 from the roots. It results from this, that the growth of trees in diameter is 

 the result of a local developement ; and that the organic matter of this increase 

 does not descend from the upper parts of the trunk, as some physiologists 

 still think. {U Hermes, Dec. 24, 1836.)

A'LNUS incdna is now beautifully in flower in the Horticultural Society's 

 Garden ; and^g. 55. will give some, though but a faint, idea of the beauty of 

 the male catkins of this tree. Fig. 56. represents A. viridis Dec, and our Arb. 



Brit.; A. fruticosa Schmidt; A. ovata Lodd. Bot. Cab., t. 1141.; and 5etula 

 ovata Wats. Dend. Brit., t. 96. This beautiful shrub, to which botanists have 

 given so many different names, forms the connecting link between the alders 

 and the birches ; having the branching female catkins of the alder, and the 

 samara, or winged seed, of the birch. It is now in flower, both in the Horti- 

 cultural Society's Garden and at Messrs. Loddiges's ; and we earnestly recom- 

 mend our readers to purchase a plant of it, of A. incana, and of A. cordifolia 

 (see Arb. Brit., No. viii. pi. 232.), and to plant them in good soil, within 

 the reach of water, where they will soon grow 

 vigorously, and flower freely every winter. A. cor- 

 difolia Qfig. 57.) is a magnificent tree, with fine, large, 

 smooth, deep green, cordate leaves, by far the hand- 

 somest of the genus ; and, though there are abun- 

 dance of plants of it in the nurseries, it is rarely to 

 be met with beyond their precincts. The only tree, 

 not in the environs of London, that we know of, is at Britwell House, Bucks, 

 the residence of W. H. Miller, Esq., M.P,, from which a specimen was lately 

 sent to us by W. Christy, jun., Esq. — Cond.

A Root of Horseradish, 7 ft. 4 in. long, was shown us, Feb. 10., by Mr. 

 Arthur Kimber, late cottage-gardener to the Duke of Leinster at Waters- 

 town, near Maynooth, and now out of place, and at work in the Hammer- 

 smith Nursery. It was grown in soil trenched to the depth of 10 ft., and 

 mixed with rotten leaves, sand, and a little spent hot-bed dung, and placed on 

 a stratum of small stones, as drainage, 1ft. thick. The cutting, about 3 in. 

 long, was planted in Feb., 1835, and the plant taken up on Jan. 8. 1837. The 

 upper part of the root is more than half an inch in diameter, and the lower
