*^* As only a few of the Plates relating to Natural Hiftory are referred to in the articles of the Cyclopaedia which 

 they are intended to illullrate, it has been deemed unneceffary to incorporate the fubjefts of them in the Index. The 

 fyftematic arrangement and minute analyfis of them in the annexed Catalogue will, it is conceived, be found amply fufficient 

 for every purpofe of reference and confultation.
