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. 



^rmeniaca nepalensis is nothing more than the common apricot. 



Cerasus boreahs and C. persicifolia ai-e the same. 



C. hyemalis is the same as C. nigra. 



C. grse^ca is a variety of C. Mahdleb. 



Prunus 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 salicifolia 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,i?. macrocarpum, R. aureum, R. luteum, 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. 



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

 all the American kinds may be reduced to one species. 



Praxinus americana produces numerous varieties from seed. 



ilforus 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. 



C/'lmus campestris tortuosa is tlie 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 Jforus 

 alba italica, and this variation is continued by grafting. 



Celtis TournefortM and C. orientalis are considered the same. 



Populus grse^ca, grandidentata, trepida, and tremula are varieties of one and 

 the same species. 



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

 perhaps, essentially the same species. 



P. vistulensis, which produces finely [veined wood, much used for small cabinet- 

 work in Berlin, is P. nigra. 



Pinus Laricio is 75 ft. high. 



We omit giving the dimensions of a number of large speci- 

 mens of trees in the Jardin des Plantes, as they were taken by 

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

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



Fontainebleau. — July 29. to 2>\. MM. Vilmorin and Poiteau 

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

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