glaCs in the windows were broken, through which mucli of the fnioke 

 of the fulphur had efcaped, or elfe, that the moths which I now faw, 

 had come out of their aureha ftate after the fumigation was over ; for 

 I am well aflured, that io long as the moths are inclofed in their 

 aurciia cafe, or covering, the fmoke of fulphur cannot do them any 

 injury. Therefore it will be neceflary for thofe who may chufe to 

 fumigate th^ir granaries in the manner I have recommended, to be- 

 gin the operation as foon as ever the moths appear, that they may

 fome days, indeed as long as any moths are to be feen, becaufe 

 tbefe creatures do not all com.e out of their aurelia ftate at the fame 

 time. The expence of fumigating is no obje6i, for a pound of ful- 

 phur may be bought for a trifle, and it is in no fort injurious to the 

 wheat, nor is it prejudicial to tlie health of any perfon, but rather 

 falubrious.* 



Towards the end of fummer, when the maggots quit the wiieat, 

 and creep up the walls, tliey may eafily be fwept down and dellroyed, 

 for this infe6l is a very tender animal, and foon killed. And tliefe 

 precautions being obferved, very few moths will be feen the fol- 

 lowing year. 



Some of the eggs laid by thefe moths I put in glafies by them- 

 felves, which I carried about in my pocket, others of them I placed 

 in my ftudy, and I obferved that thofe which I carried about me 

 were, by the lieat of my body, mucli fooner hatched than thofe 

 which W'cre in my lludy, for thefe latter were fixteen days before the 

 maggots crept out of tliem ; but at I'even days end thofe in the for- 

 mer made their appearance. 



One of thefe maggots, when newly hatched, I put into a glafs 

 tube, tlie infide of which was about the fifth part of an inch wide, 

 and having placed this before the microfcope, I gave it to the limner
