genus, thereby imperceptibly leading him to -a knowledge of the whole sys- 

 tem. This has greatly increased the labour of the author ; but the utility is 

 so manifest, and has been so decidedly approved, that he will submit cheer- 

 fully to the task, as often as circumstances will admit." This work is of 

 particular interest to the gardener ; and we only regret, that- the price 

 which must necessarily be charged for it, on account of the plates, will al- 

 most limit its use to their employers. We would recommend such of the 

 latter, as wish to look on nature with the eye of a naturalist, to take it in 

 as a rich source of gratification to themselves, and for the purpose of lend- 

 ing it to their discerning gardeners, in order to enable them to know better 

 how to destroy the insects in their gardens. 

 Conrad Loddiges fy Sons, Nurserymen, Hackney, Authors of the Botanical 



Cabinet: Catalogue of Plants in their Collection. London, 12mo. . 



This Catalogue exhibits such an assemblage of plants, as, we will venture 

 to assert^ was never before brought together by any individual, not ex- 

 cepting sovereigns, either in this country or abroad. The total number of 

 species exceeds 8,000; all plants that may be purchased, and exclusive of 

 about 2,000 varieties. In two departments, the most superficial observer 

 will acknowledge the superiority of the Hackney garden ; that of palms, 

 and that of hardy trees and shrubs; the total number of species of the 

 former at Hackney is 1 20, of the latter 2,664. There is no such collection 

 of hardy trees and shrubs in the world; and when it is considered that 

 they may all enter into our plantations, their value to the country is in- 

 calculable. In this department, Messrs. Loddiges have done more than all 

 the royal and botanic gardens put together. The number of trees and 

 shrubs in the Hackney garden, is not less remarkable than the manner in 

 which they are arrranged, along a revolving gravel walk, by which every 

 individual species and variety may be examined with ease, and compared 

 with its congeners at any time of the year. A plan of this arboretum we 

 have already given. {Encyc. of Gard. § 7356.) 



In confirmation of these remarks, we subjoin the number of species of 

 some of the principal genera.
