In No. VIII. there is a memoir on acclimatising plants, in 

 which the principle laid down is, that every exotic tree, in which 

 vegetation is not suspended during winter, is incapable of being 

 acclimatised in countries where the native trees have no sap in 

 the exterior of their trunks (that is, no descending sap) during 

 winter. Deciduous herbaceous plants, from warm countries, 

 may be acclimatised, or rather grown, in cold countries, by 

 covering the ground in which they are planted, during winter, 

 with such a covering as will exclude frost. Plants with buds on 

 their roots, whether ligneous or herbaceous, from warm countries, 

 may generally be preserved by the same means ; and hence the 

 Bouvardz'a triphylla from Mexico, and the Chilean fuchsias, 

 though they die down to the ground every winter, yet, the roots 

 being furnished with buds, when they are slightly protected, they 

 never fail to send up shoots the following spring. The pelar- 

 goniums, on the other hand, having few buds on the roots, and 

 having these and the stems succulent, can seldom be preserved 

 through the winter in the open air. The period at which plants 

 vegetate in their native country materially influences their sus- 

 ceptibility of acclimatisation. The plants of the south of Chile 

 vegetate in their, native country at a time corresponding with 

 our winter; and as they preserve their habit of vegetating at 

 that time here, they never can be perfectly acclimatised unless their 

 period of vegetation could be retarded by giving them a new 

 habit. It is suggested that this might be done by keeping them 

 in the shade, and in a low temperature, until it was desirable 

 that they should vegetate. There are a number of other inter- 

 esting remarks in this article, chiefly taken from Humboldt. 



No. X. contains recollections of a botanical and horticultural 

 tour in England, in the summer of 1833, by the editor, Dr. 

 Courtois, who was accompanied by M. Makoy. This is one of 

 the most intelligent and correct narratives of a gardening tour in 

 Britain, by a foreigner, published in a foreign work, which we 

 have seen. In general, such tours are full of misspelt proper 

 names, and misconceptions of objects. Even the tours of M. 

 Soulange-Bodin and M. Lenne, noticed in our first volume, 

 though much more perfect than those of preceding and sub- 

 sequent gardening tourists, are still liable to these objections. 

 Dr. Courtois was struck with astonishment at the extent of the 

 garden establishments in the neighbourhood of London, and 

 could not conceive how the nurserymen could find sale for such 

 an immense mass of plants. He was delighted with the small 

 suburban gardens, and with the beautiful plants he saw in those 

 of even a few yards square. He was pleased to observe pots of 

 flowers in many shops, and in the windows of most small houses ; 

 but, above all, he was charmed with the English parks and 

 pleasure-grounds. In speaking of the nurseries, he considers
