On the first appearance of this Journal, I bore my humble testi- 

 mony to its value and utility. So far from having receded from its 

 original excellence, it seems to have improved. There are, however, 

 one or two points open to criticism, and as honest criticism has 

 wrought a wonderful change for the better in the numbering of the 

 plates of another journal, I may venture to hint it is susceptible of 

 improvement here. Instead of the present obscure method, each plate 

 should be legibly headed ZOOLOGY, Plate I., or BOTANY, 

 Plate I., and the plates intended to illustrate a paper should appear 

 simultaneously with that paper. The plan of compelling a non- 

 subscriber to purchase two numbers of a journal in order to procure 

 one paper is one of the most hackneyed, and at the same time one of 

 the meanest tricks of scientific journalism. The Linnean Society 

 must not descend to it. The instance to which I allude is the paper 

 by Mr. Hicks, bearing a most inviting title: in order to make it intel- 

 ligible this paper appears to have been liberally illustrated, and this 

 illustration is absolutely requisite : a great number of references are 

 made to a Plate V., but Plate V. is unpublished, and should the 

 Society again revert to its long-interval mode of publication, the 

 Fellows now living may hardly hope to obtain it.
