roses on briar or rose roots is recommended ; a practice which, we 

 believe, has been partially adopted by some British nurserymen. 



In Nos. XI. and xji., which complete the first volume, there 

 is a note on the culture of ZJaphne Cneorum, by M. Jacob 

 Makoy, in which he says the great art of managing this plant is, 

 not to overcharge it with water at the roots. The silver and 

 balm of Gilead firs, and, in general, all such as, like them, have 

 their leaves flat and hollowed, are said not to lose their leaves 

 by the dessication of their branches, like the spruce firs; a fact 

 of some importance while branches of these trees are used for 

 the purposes of protection. The mistletoe is spread over the 

 greater part of Europe and Northern Asia ; but is never found 

 on high mountains. In Belgium, it is common on apples, pears, 

 and thorns, principally in the hilly part of the province of 

 Liege. The reason given by Decandolle why the mistletoe will 

 live on different species of trees is, that it pumps up for its use 

 the ascending sap from the alburnum, and not the elaborated, or 

 descending, sap from the bark. On this account, also, it hurts 

 the tree much less than if it lived on the descending sap. The 

 mistletoe affords a proof that the ascending sap differs very little 

 in different trees. Branches, in general, do not elongate after 

 their annual shoot is completed ; but the contrary is said to be 

 the case in Thuja, Juniperus, and Cupressus. The forms and 

 the colours of plants may be preserved by first sprinkling them 

 with the powder of Lycopodium, or, probably, with meal or 

 flour, and then placing them in a close case containing muriate 

 of lime. The muriate powerfully attracting humidity, the plants 

 are rapidly dried. This mode might, perhaps, be found suitable 

 for succulents. At the moment of concluding the twelfth 

 number of his work. Dr. Courtois saw in flower Camellm ja- 

 ponica Doncklaer/, so named after the head gardener at the 

 botanic garden at Louvain. It is said to be one of the finest 

 varieties in the trade, and may be had at Makoy's nursery. 



We have not noticed a few topographical and other errors in 

 this work, because, on the whole, it may be designated as accu- 

 rately and respectably got up ; and we have no doubt it will be 

 of essential service to the botanists, floriculturists, and horticul- 

 turists of Belgium.

The contents of this periodical are, as usual, varied ; and, in 

 a scientific point of view, highly interesting. In p. 320., six 

 sorts of Xizyphus are described as among the fruits cultivated in
