"The first edition of this celebrated work," which is incontestably of the greatest utility to 

 gardeners, and, mdeed, to all who have not access to great libraries, consisted of 1159 pages- the 

 latest in our possession filled 1329 pages; that now brought before the public occupies no fewer 

 than 1574, forming a solid, massive volume of small print, comparable to nothing so well as to 

 a dictionary. The great recommendation of the work has always been its woodcuts ; which 

 although only miniatures, were nevertheless drawn by Mr. Sowerby with such happy art, and 

 80 skilfully engraved by Branston, that the plants could always be recognised, even by those 

 little acquainted with the vegetable kingdom. The continuation in the form of supplements 

 is executed in a manner more than worthy of the original, and brings down the subject to the 



latest possible moment How many figures the work contains we are unable to ascertain 



pu^ we estimate the number of plants actually represented by good woodcuts as amounting 

 to flometmng more than nine, thousand! " Oardenerr' rHpr,wT/^r,r
