part of your other cocoons, which is called the downy tow, 

 and which is quite feparate from the filk ; you put the cocoons 

 in large bafl^ets, furniflied on the infide with a coarfe brown 

 paper : when the oven is heated at the common degree for 

 baking bread, you may put the bafkets into it, and leave 

 them there for about two hours, till you hear no more the 

 rattling noife of the infeds, as they move and ftir about on 

 account of the heat which they feel during that time. 



Take care afterwards to wrap up thofe cocoons in a blanket, 

 in order to kill entirely thofe who lliould not have been choaked 

 by the heat of the oven. 



C32d Que.) How to manage the cocoons intended for eggs ? 



(Ans.) We forgot to mention before, that in the choice 

 of cocoons, particular care muft be taken to referve an equal 

 number of males and females. The male cocoon is fharp^ 

 pointed, while the female is round at both ends. This choice 

 made, the cocoons ought to be divefled of that downy cover 

 heretofore mentioned. Then you firing them together, males 

 and females alternately upon a coarfe thread ; but you muft. 

 take care that the needle fliould not go further than into the 

 furface of the cocoon, in order not to hurt the chryfalides, 

 nor to open any way to the air ; hang this firing of cocoons 

 in a dry and airy place till the butterfly comes out. 



Upon a common average, one pound of cocoons will 

 produce one ounce of eggs.
