the fight of an inceflant motion a})pcaring withui its head (and, if 

 I may be allowed the exprcfTion, in its brain), for this motion was 

 as regular as we can imagine, juft as if we were to fee the motion 

 of the lungs of any animal in rcfpiration. 



Sometimes I faw one of thefe minute maggots open its mouth, 

 as if in quell of food, at the fame time producing a minute globule 

 of air at its mouth, which, palfing through the head, went into its 

 throat. 



Moreover, I caufed one of thefe maggots to be drawn when fo far 

 grown, that its body was the tenth part of one full grown, and 

 which is reprefented at //^'. 5, OPQ R ; in which figure, PQ is the 

 head, and the retl the body. Thefe maggots, when young, lie in 

 a curved pollure, but, when almoll full grown, they aliunie u 

 llraight figure. This maggot was drawn from a microfcope, mag- 

 nifying objects much lefs than that from which the former figures 

 were taken ; from whence the minutenefs of thefe eggs may very 

 eafily be conceived. I could have given a drawing of a full grown 

 maggot from the microfcope, but I think it uTinecefTary, becaufe, 

 from the laft figure, we can eafily form a judgment of a maggot, of 

 the fame fiiape, when ten times larger. 



I muft confefs, that I formerly thought no othcrwife than that 

 thofe maggots to which, hitherto (for want of knowing better, we 

 have given the name of Ants' eggs), as feen by the naked eye, were, 

 in reality, the eggs of the Ant, and that tiie black fpot which we fee 

 in their bodies was the minute young Ant, not yet brought into life. 

 But I cannot fufficiently \\onder, how any one can fufier his imagi- 

 nation fo to deceive him, as to fancy, when ufing a microfcope, that, 

 through it, he fees in this egg (as we call it) a young unformed 

 Ant. And not only fo, but to make a drawing reprefenting its body, 

 head, claws, and eyes; when, on the contrary, no perfon what- 

 ever can foe the leafl: appearance of any fuch in this maggot \\ hich, 

 hitherto, has been called the egg.
