Out of the Italian $ournal y being a Defcription ef a Microfcope 
of a New fafhion, by the means whereof there hath been [een an 
Animal leffer than any ofthofefeen hitherto. 
EUftachio Divini hath made a Microfcope of a new Invention, 
wherein inftead of an Eye-glafs convex on both fid** 
there are two plano-convex Glaffes, which are fo placed, as to 
touch one another in the middle of their convex furface. This 
Jnftrument, of which Hon. Fabri treats largely in his Ofticks 
{viz. Prop. 46.) hath this peculiar, that it (hews the Objects flat 
and not crooked, and although it takes in much, yet neverthe- 
lefs magnifieth extraordinarily. 
It is almoft 16' inches high, and adjufted at 4 different 
lengths. In the fir /?, which is the leaft, it (hews lines 41 times 
bigger than they appear to the naked Eye : In the fecond, 90 
times : In the third, m times : and in the fourth 143 times. 
Whence one may eafily calculate, how much it augments furfaces 
and folidities*. 
The Diameter of the Field it difcovers, or the fubtenfe of the 
vifual angle,meafured upon the Obje&-plate,in the firft length is 
of 8 inches and 7 lines : in the fecond> of 1 % inches and 4 lines : in 
the thirds of 13 inches : and in the fourth, of a little morethart 
16 inches. 
As they viewed with this Microfcope the little grains offand 
fearced, they perceived an Animal with many feet, its back white 
and fcaly, but lefs than any of thofc hitherto obferved. For, 
although the Microfcope {hewed every grain of fand as big as an 
ordinary Nut, yet this Animal appeared no bigger than one of 
thofe grains of land feen without a Microfcope. Whence may be 
concluded its fmalnefs, which occafion'd one of the beholders to 
give it the name of the Atome of Animals.
