tlie edge of the Wing were longer thtn the others, and 
of a particular fliape, Fig. 13. Ihews five of them. 
Thofe Eggs which were laid about the 15/^. of A%/ 
and were not kept warm, but laid in my Clofet-win- 
dow, were not hatcht till about the lotk of June; fo 
that the warmth of the Body haftens their hatching. 
The Corn-Merchants obferve them not till about Ah- 
gufi^ though they are hatcht in about fixteen days after 
the Moth flies about, and are not perceived by reafbn 
of their fmallneft, and their hiding themfelves in the 
firft Grain of Corn that they eat into, and are not feeo 
till they^ quit that for another. 
Thefe Worr&s are not only deftruftive to Corn, but 
are alfo in old Timber, Books, Boxes, Woollen Stuffs,

fetting it on fire, left it, fliutting the Door, and after 
two days I came again, and found fome Moths alive 
on the Walls, but not a tenth of what ufed to be there, 
and which I judged might get into the Room through 
the broken Glals of the Window, br they might have 
crept out of the Aurelia after the Smoak was over : 
WJierefore the beft way is to fmoak the Room as foon 
as the Moth appears, and that for fome days fucceffively,
