V26 Dr. Maton's and Mr. Rackett's 
considerable, to detail what was known by his predecessors, with- 
out making additions of his own. With regard to system, Gesner 
trod pretty nearly in the steps of Aristotle. In making a fourth 
class, denominated Anoniala, he can scarcely be said to have im- 
proved the arrangement of the Grecian philosopher; and even if 
his genera of Balani, Penicillce marina, Tubuli marini, and Echini, 
can be considered as more properly placed here than in any one 
of the Aristotelian classes, it was certainly very injudicious to 
include the Stelhe mariiue and Medusa among Testaceous animals. 
LINOCIER, 
the well-known copyist of Gesner, gives a brief account of a few 
shells, with figures, in his " Uistoire des Po'mons" 
IMPERATO. 
Francesco Imperato was the editor of a work on natural history 
composed principally by his father. The figures, which are far 
from being- either rude or incorrect, relate principally to fossils : 
they are few in number, but the description of shells occupies 
several pages, and, though devoid of system, proves the author 
to have paid considerable attention to this branch of zoolog} r . 
Besides giving the labours of his father to the world, Francesco 
published two treatises of his own, one entitled " de Fossilibus 
Opiiscuhtm" and another, " Discorsi intorno a diverse Cose Naturali" 
Both of these came from the press at Naples, and deserved, as 
well as the work first mentioned, to be considered as very respect- 
able additions to the scientific literature of that day. The treatise 
on Fossils contains some figures under the correspondent descrip- 
tions ; but the miscellaneous work is destitute of any, and indeed 
does not treat particularly either of recent or of fossil shells.
