^ving. OR is the mufcular part, by means of which, not only the 

 wing is put in motion, but doubtlefs many lefler mufcles are derived 

 from this, by means of which, that part of tiie wing at WXY is 

 extended in length, and the part at Y O expanded in breadth: at 

 S T is the minute wing; I mentioned above. 



When we duly confider this mod perfe6l workmanlhij) of the 

 Divine Artift, we mufl confefs, that thofe things which we difcover 

 by our microfcopes and induftry, are but as the fhadow of thofe 

 which hitherto remain concealed from us, not only in fuch fmall 

 animals as this now under confideration, but alfo in larger animals, 

 and in plants. 



It is to be hoped then, that the enquirers into Nature's works, by 

 fearching deeper and deeper into her hidden myfteries, will more and 

 more place the difcoveries of thofe truths before the eyes of all, io as 

 to produce an averllon to the errors of former times, which all thofe 

 who love the truth, ought diligently to aim at. For, 



We cannot in any better manner, glorify the Lord and Creator of 

 the Univerfe, than that, in all things, how fmall foever they appear 

 to our naked eyes, but which yet have received the gift of life, and 

 power of increafe, we contemplate the difplay of his Omnifcicnce 

 and Perfe(5tions with the utmoft admiration.
