Colour like a Loufe, that runs fwiftly 
by Starts or Stops, and is commonly found 
on the Leaves and Covers of Books, or 
amongfl rotten Wood : it is called a Wood - 
Loufe , or Wood-Mite , and is known almofl

are of a golden Colour, and can be drawn in

Iv, and, what is dill more wonderful, a 
Motion of the Brain is feen.

calls the Pediculus Pulfatorius , or Death- 
Watch (in Phil. Tranf Numb. 291,) where - 
he fays the Pediculus Pulfatorius and the 
Scarabceus Sonicephalus are the only two In- 
feds that make regular clicking Nolles like 
the Beat of a Pocket-Watch.
