317 
This chapter will be divided into seven para- 
graphs. 
1 . Facts relative to the eggs of the silk-worms, 
and to their hatching. 
2. Facts relative to the extent of space which 
should be occupied by the silk-worms, in their dif- 
ferent ages. 
3. Facts relative to the consumption of mul- 
berry-leaves by the silk-worms, in their different 
ages, and observations on the subject. 
4. Facts relative to the increase and decrease of 
the silk-worms in weight and size. 
5. Facts relative to the cocoons containing the 
healthy chrysalis, the diseased chrysalis, or the 
dead chrysalis. 
6. Facts relative to the production of the eggs. 
7. Facts relative to the buildings and utensils. 
1 . Facts relative to the Eggs of the Silk-worms , 
and to their Hatching. 
To compose an ounce of eggs of the largest 
breed of silk-worms of four casts, it will require 
37,440*. 
* I must remark that the ounce here understood by the 
author, is smaller than the French ounce. From the infor- 
mation I could get, I found that 28 Lombardy ounces are 
about equivalent to 25 French ounces. It is from this, that 
I have reduced all the calculations into French measure. 
My reckonings may not always be exactly correct, but upon 
the whole, I believe they will be found free from any material 
errors . — (F rench Translator.)
