In the work, the plan of which is now submitted to the notice 

 of the public, it is proposed to give descriptions and figures of 

 the more remarkable new or imperfectly known plants contained 

 in an herbarium of two thousand species, collected by Dr. Hors- 

 field, and placed by him in the museum of the Honourable East 

 India Company. 



The work will consist of two parts, forming together a volume 

 of moderate size. Each part will contain 25 plates, and about 

 100 pages of letterpress. The size of the work will be a large 

 quarto ; and several double or folio plates will be contained in 

 each part, for the illustration of large subjects. The descriptions 

 will be oriven in Latin : the observations in English. It will be 

 published with coloured and uncoloured plates; the price of the 

 coloured copies will be 3/. 105. each part, and of the uncoloured 

 copies 21. 105. each part. The second part is in progress of 

 preparation, and is expected to be ready early in the ensuing 

 year, 1839. Messrs. W. H. Allen and Co., booksellers to the 

 Honourable East India Company, will be the publishers of the 

 work in England. — Ajnil 2. 1838.

BEfELOPEMEST of the Bark in Trees. — The distinct developement of the 

 bark consists, sometimes, in the thickening of the cork substance; at others, 

 in the thickening ot the cellular envelope. There are, however, manv cases in 

 •which the great increase of the bark substance consists chiefly in the ex- 

 pansion of the layer of liber; and we may cite, for instance, the beech (jPagus 

 sylvatica). In this tree, the bark almost always remains even, and the 

 cellular envelope continues very small, even when the bark has become 

 of considerable thickness. The bark, also, of the plane tree (Platanus occi- 

 dentalis), which is found in this country, must also be specially mentioned. It 

 exhibits the same structure as the bark of the beech ; remaining, however, in 

 this state only from the eighth to the tenth year. About this time, there 

 forms in the layer of liber (that is, only at some places) a delicate layer of 

 tabular cells, which agree exactly with that of the periderma. This new' layer
