‘may place them on a linen cloth difpofed vertically, as 
againft a wall, or on a line, &c. where they couple and 
are joined during twenty-four hours. This over, the fe- 
male lays her eggs during other twenty-four hours; after 
which fhe dies, as does the male; this their fecond life, if 
I may be permitted the term, is only of forty-eight hours 
‘duration. When the eggs are new laid, they are about 
the bignefs of a common pin’s head, and of a ftraw co- 
lour ; by degrees they become black, aflume more folidity, 
Jofing at the fame time part of their bulk. 
When they are arrived at this point, you muft feparate 
them from the cloth; to effet which, you mutt dip them 
into a large pan filled with one half water and the other 
half wine, rather more than lukewarm ; when your cloth 
has foaked in this liquor.a little while, you may feparate 
them from the cloth with a filver fpoon and dry them in 
a funny place, and take them away when they begin to 
be whitifh. 
When you have thus detached your eggs, you muft 
keep them till the next year in a cool damp place to pre- 
ferve them from hatching during the great heat, which 
would ruin the projec. 
On the arrival of the fpring, you muft obferve when 
the mulberry tree begins to put forth its leaves, which 
muft be your fignal to expofe your eggs in a very warm 
place, that they may all hatch at once, otherwife they 
would only hatch by little and little, and in proportion as 
each individual would be arrived at the point of its natu- 
ral maturity. In which cafe the pains required to fepa- 
rate their different claffes would be exceflive, not to fay 
impoflible. To hatch your egys you muft carry them 
about you nine or ten days, keeping them in your bofom, 
or other parts near the body; in the night you may put 
them between the matraffes of the bed. You may like- 
wife hatch them by the heat of an oven, but this method 
is s- dampatous, becaufe you may poflibly burn the worm
