500 NOTICE OF ENTOMOLOGICAL WORKS. 



X. 



In generatione plantarum et animalium simplicissimorum a causis 

 elementaribus destinatur, utrum particula aliqua materias organi- 

 zandse planta, an animal futura sit. 

 XI. 



A massae nervosa copia proportionali et processus respiratorii 

 gradu in genere animalium magnitudo dependet : ideo Insecta et 

 Ara;nidae molis tam exiguoe sunt. 



XII. 



Organisatio infusoriorum perfectior, a celeberrimo Ehrenberg

 cliaracter of the work would have been raised, by anatomical 

 figures of the mouth of each genus; but we suppose these 

 have been omitted as likely to injure the general appearance 

 of the plates, with which we are so delighted, that we feel 

 little inclined to say anything about the letter-press ; but duty 

 must be attended to, and we therefore inform our readers that 

 this part of the work is no improvement: how Mr. Gray 

 could trust himself on such a task, we cannot think ! he 

 should have taken Stoll and Audinet-Serville, and studied 

 them for vveeks, before he ventured on Ortlioptera. He says 

 of the Piiasmidce, " they belong to the first section, Cursoria, 

 or walkers, and differ very much from the other family of the
