spun, and dyed silk exported (leaving out the rest) 
abroad, proceeding from the provinces which com- 
posed the ex-kingdom of Italy, amount to eighty 
millions, an amount less than in 1810, of which the 
following is the account, (§ 1.) : — 
Livies; 
1. I will suppose that 90 lbs- of cocoons arc ob- 
tained from an ounce of eggs, instead of 45 lbs., 
which, on an average, is now the common quan- 
tity. Half the number of cocoons kept for the 
produce of eggs will be saved. (Chap. IX.) 
This half of the quantity of cocoons, which would 
yield exportable silk, amounts to 800,000 
2. If silk- worms are reared so that 21 lbs. of leaves 
should produce about 1^ of cocoons, whilst just 
now 25 lbs. of leaves are wastefully consumed to 
produce that weight, as, on an average, they 
reckon 1050 lbs. of leaves necessary to produce 
60 lbs. of cocoons; we should thus have, unde- 
niably, a quantity equivalent to a quarter more ; 
its value would then rise to about . . . 20,000,000 
3. I will suppose that by good management the 
losses decrease only 10 per cent., this will pro- 
duce in more or less time .... 8,000,000 
4. Admitting that the cultivation of the mulberry- 
trees improves and plantations increase, we must 
suppose the production of leaves will augment 
10 per cent., which will be an increase of the 
production of cocoons amounting to . . 8,000,000 
5. Supposing the amelioration in the art of rearing 
the silk-worm, the cocoons obtained from good 
and well-managed laboratories, in equal quan- 
tities with those obtained from ill-directed labo- 
ratories, will yield 10 per cent, more silk, as ex- 
perience every day testifies. The value of this 
amelioration will amount to ... 6,000,000 
Total 42,800,000*
