skin ; 3rd, from their sharp and stretched feet ; 4th, they 
eat little, languish, and are in a state of atrophy. 
When there are very few worms attacked by this disease, 
they may be nursed in the infirmary ; but as I am persuaded 
they never will answer, it is better to throw them away ; and 
if before the first casting or moulting the whole brood ap- 
pear to be infected, then I must insist on the whole being 
thrown away, and a new brood hatched from fresh seed. 
Of the Shining, or Glow, or Luisette. 
There are in general but few worms attacked by this dis- 
order. It will appear after the moultings, and most com- 
monly after the fourth moulting. It does not proceed from 
any defect in the process of hatching, as some pretend, but 
rather from some failing in the coupling or in the laying of 
the egg. The worms attacked by this disorder feed like 
the others, and grow in length exactly in the same propor- 
tion, but not in thickness. This disease is perceptible by 
the colour of the worm, which first appears of a clear red, 
and then changes to dirty white. If attentively observed, it 
will be seen to drop a sort of viscous humour from the silk 
drawing tubes, or spinners, and that its body is transparent, 
which has occasioned it to be called luisette, or glow-icorm, 
the luminous insects that shine in the summer night. The 
moment these glow-worms or luisettes are discovered on the 
wicker hurdles, they must be thrown away. These worms 
consume leaves without ever spinning good cocoons. 
After the fourth moulting, some glowing luisettes may be 
found inclined to form the cocoon, moving their heads about, 
and seeking a place to fix this silk. They must not be 
allowed to waste their strength and silk in useless efforts ; 
and if they have reached their point, they r may have a chance 
given them, by being put into baskets, with small branches 
to assist them to form the cocoon. 
Dragees, or IVh itc Comfit. 
This is not properly a disease of the silk-worm, because 
when the cocoon is formed, when this name is given it, a
