very shallow and dry below, and economy a main object, it might be ad- 

 visable to renew the peach trees on a wall, by planting the nuts where 

 the plants are finally to remain. 



The Peche d'Espagne, or wild peach, produces double flowers, which inva- 

 riably appear fifteen days later than those of the common double-flowered 

 peach. This seems a very desirable variety with a view to prolonging 

 the season of double peach blossom, and we are not aware of its being in 

 British gardens. Were French postage as cheap as that of Britain, 

 cuttings might easily be sent by letter in the budding season. 



Jrmeniaca nepalensis is nothing more than the common apricot, 



Cerasus borealis and C. /jersicifolia are the same. 



C. hy emails is the same as C. nigra. 



C. gra;^ca is a variety of C. Mahalcb. 



Primus reclinata is a variety of the common plum, and is the same as P. 

 nigra. 



P. Padus has produced a variety with spotted leaves, like those of aucuba. 



Cratae'gus Crus-galli ^alicifolia has produced seedlings with broad spatulate 

 leaves, deeply notched. 



Ribes has varied exceedingly from seed. R. cereum has produced deep green 

 leaves, three or four times larger than those of the species. R. pal- 

 matum.P. macrocarpum, R. aureum, R. liiteum, and R. tenuiflorum are all 

 produced from the same seed. 



Symphoricarpus racemosus has produced a variety which retains the fruit all 

 the winter, and is very distinct. It ought to be procured by British 

 nurserymen. 



J)iospyros virginiana has produced several varieties ; and M. Camuset thinks 

 all the American kinds may be reduced to one species. 



P'raxinus americana produces numerous varieties I'rom seed. 



il/orus alba italica has, as already mentioned, the soft wood, or alburnum, 

 of the young shoots red. Whether this is peculiar to M. alba italica, or 

 constitutes a subvariety or a variation of the Italian mulberry, M. 

 Camuset is uncertain. 



Maclur« aurantiaca bears fruit every year ; but, the male plant not having yet 

 produced flowers, the fruit does not ripen. 



Z7'lmus campestris tortuosa is the only elm which grows freely by cuttings, 

 and is always so propagated in France. The tree is much prized in 

 France for the timber ; which, having the grain or fibres very much twisted, 

 will not split, and is therefore much used for the naves of wheels. 



U. campestris latifolia, the U. montana of Bauh., has, as before stated, been 

 found with the alburnum of the young shoots red, like that of il/6rus 

 alba italica, and this variation is continued by grafting. 



Celtis Tournefort/i and C. orientalis are considered the same. 



Pdpulus graeVa, grandidentata, trepida, and tremula are varieties of one and 

 the same species. 



P. monilifera, canadensis, ietulifolia, undulata, and probably P. nigra, are, 

 perhaps, essentially the same species. 



P. vistulensis, w hich produces finely^veined wood, much used for small cabinet- 

 work in Berlin, is P. nigra. 



Pinus Lan'cio is 75 ft. high. 



We omit giving the dimensions of a num.ber of large speci- 

 mens of trees in ihe Jardin des Plantes, as they were tatcen by 

 M. Camuset in 1837, and forwarded to us by Professor Mirbel, 

 and will be found in their respective places in the Arboretum.

 accompanied us to Fontainehleau by the diligence, and we re- 

 turned by the Seine. Between Paris and Ris the soil is deep,
