•tongue was thickefr. In this i'niall piece are to be feen various mi- 

 nute mufclcs, cut tranfverlcly, which are reprefcntcd between 

 BCKL, and DEHI; and among thefe, again, there appear 

 many exceedingly minute particles, alfo cut traniVerlely, whicii, 

 "by reafon of their fmalhiefs, could by no means be reprefented in 

 the drawing, but each of them may, in fa6t, be confuiered as a 

 mufcle, for if, by the microfcope, we were to difleft the before men- 

 tioned minute mufcles, we fliould find them compofed of fmaller parts, 

 like a large mufcle, when diire<5ted and vie\\ed by the naked eye. 



Thel'e flelhy mufcles, thus cut tranfverfcly, conflitute the i'ub- 

 ftance or thicknefs of the tongue ; and the mufcles pictured at tiie 

 three places in this figure, ABL M, C D I K, and EFG H, which 

 are fliewn lengthwiie, extend along the tongue from end to end. 

 And, as between the letters B.C K L and DEHI, is fliewn how the 

 flefliv mufcles appear, when cut tranfverfely, fo at ABLM, CDIK 

 and E FGH may be feen their figure when cut longitudinally. 



All thefe flelhy mufcles, taken together, are not larger, when 

 viewed by the naked eye, than the fmall piece or particle fliewn at 



I alfo judged it right, to take off" one of thefe flefliy mufcles, length- 

 wife, and to caufe a drawing to be made of it, to exhibit to the eye 

 its true formation, and alfo, as nearly as pofllble, to fliew thereby, 

 how, in the motion of the tongue, thefe mufcles are exerted, and 

 liow^ they change their figure. 



Fig. 2, NOPO, reprefents this flefliy mufcle, which I took off 

 length wife, preferving the whole of its thicknefs, io that none of its 

 conltituent parts were broken off", except at the extremities N O and 

 PQ : in which mufcle feveral bendings are to be feen. 



Now, fuppolmg this mufcle, placed lengthwife in the tongue, to 

 be contradted in bendings, we muff conclude, that the tongue then 

 becomes flioiter and tliicker, and the mufcles which lie acrofs it, arc
