which may have been famihar in gardens under names, 

 which in order to meet the requirements of science, real 

 or supposed, it may have been found necessary to change 

 or suppress. A few wholesale suppressions, such as 

 that of referring all the species of Cattleya to Bletia, 

 and other cases of a similar kind, are so little likely to 

 be followed out in gardens, that we have passed them 

 over with a general record that such changes have been 

 proposed. For assistance of this nature, and for having 

 devoted much attention to the amended descriptions, we 

 have to thank our old friend and our coadjutor in the 

 work of the Orchid Album, Mr. Thomas Moore, of 

 Chelsea. 



The matter has so greatly increased since the publi- 

 cation of the last edition, that having regard to our efforts 

 to make it as perfect as possible, we have been compelled 

 to raise the price. We hope, however, that the additions 

 that have been made will meet with the approbation of 

 our readers, and be considered by them as real improve- 

 ments quite worth the increased cost. We have before 

 stated that we do not aim to instruct Botanists, but to 

 assist Amateurs, by placing before them plain and 

 practical information on a sound scientific basis, so that 

 for the time and pains bestowed on the cultivation of 

 this charming class of plants, they may be rewarded by 

 the production of fine specimens, and as a consequence, 

 abundant and beautiful flowers.
