udations ; the fir A; of the Fraxinus, and the other of 
the Jujuba Indica, and that by many undeniable Ar- 
guments. 
In the Third Bcok he (hews you what the CochineOa 
is, with many excellent Obfervations thereon. The 
Blatta Byzantina he proves to be an Operculum of a 
Turbinated Shell-fi(h , different from the Vnguu Odo-

Horn /Elianus affirms to be black, which Conje&ure An-
