twelve days a hundred eggs, which hatch in six days. 

 Suppose these produce fifty males, and as many fe- 

 males : these females coming to their full growth in 

 eighteen days, may each in twelve days lay a hundred 

 eggs more. And these in six days more may produce a 

 young brood of five thousand. So swiftly do these 

 creatures multiply ! 



Most animals are subject to lice, but each of a dif- 

 ferent kind, and none of them- like the human. Nay, 

 even insects are not free. Beetles, ear-wigs and snails 

 are particularly subject to them. Numberless little 

 red lice are often seen about the legs of spiders. A 

 sort of whitish lice are common on bees. They arc 

 also found on ants. 



Fishes, one would think, living in the water, and 

 perpetually moving to and fro, should be free from 

 iice. But they have their sorts too, which nest under 

 their scales, the salmon in particular. Besides which, 

 there are frequently found great numbers of long 

 worms, in the stomach and other parts of fish. And 

 these work themselves so deeply into their flesh, that 

 they cannot easily be got out. 



Many insects are bred in the nostrils of sheep. 

 One may take out twenty or thirty rough maggots at 

 a time. A rough, whitish maggot is found also with, 

 in the intestinum rectum of horses. Others are gene- 

 rated in the backs of cows, which at first are only a 

 small knot, being an egg laid there by some insect. 

 Afterward it grows bigger, and contains a maggot, 

 lying in a purulent matter. 



In Persia, slender worms, six or seven yards long, 

 are bred in the legs and other parts of men's bo- 

 dies. Yea, there have been divers instances of 

 worms taken out of the tongue, gums, nose, and 

 other parts, by a person of -Leicester, before many 

 'witnesses. 



11. A very extraordinary kind of insect, is that 

 which is called a Death-watch, because it makes a 

 ?ioise like the beating of a watch. They are of two*
