this is partly hid ^whcn you look on the BackJ by a thick 
Horn c on the fide of the Head. I broke off one of the 
Horns at and then it appeared as in the annexed Figure, 
which reprefents the fore part of this T/V/<, and tho' rudely 
drawn, will give you a better Idea of it^ than many words 
from an hafty Pen. 
I afterward examined the Snouts or Probofcis of Dog 
Ticks^ to fee if they had the like Conformation, and found

the lik« Waters, yet 1 never favv the A/fimalcuU fo much to 
my Satisfaftioh as in my new Glafles, which 1 have now in- 
creafed to above double the number of my firft fet. I have 
found fome of thefe Amf9ialcuU almoft incredibly minute, 
which appear even to my greateft Magnifiers not fo large 
as a Mite to a naked Eye, and in the bigger fort, 
I can plainly fee the little Feet by which rhey perform fo 
brisk Motions^ which I never could find before. But I 
doubt not but your own Microfcopcs had fliew'd you v»'hat
