when you go to dean it ; but if the hurdles 

 were made ih clofe as to hinder their Ht- 

 ter from falling through, there would be 

 no occafion for any thing under them. 



After about three days feeding of the 

 worms, which muft be managed much the 

 fame way as in their foregoing age, they will 

 begin to fall into their fourth and lafl 

 moult, which having the fame appearances 

 as the former need not be infilled on. In 

 three days they recover from it, being of 

 a colour the fame as after their former 

 moult, but their foreheads broader and 

 their feet larger and furnifhed with claws ; 

 their tails alfo broad, and furnifhed with 

 an infinite number of fine hooks, with 

 which they are enabled to cling and fup- 

 port their weight. 



N. B. If each receiver has two rods a 

 little longer than its edge, one rod may lie 

 over the pins which fupport the hurdle a- 

 bove it, inftead of making crofs bars, as 

 mentioned in the lafl paragraph but one.
