GONIOMETRICAL Lines, derived ^romy^^x, angle, 

 and i^.sTfK, Im.-afui-r, in Geometry, linu3 ulcd for meafuriiig 

 or determining the quantity of angles. Such are iuies, 

 tangents, fecants, verft-d fines, &c. 



We have a paper by Mr. Jones, in the Philofophical 

 Tranfaflions, containing a commodious difpoiltion ot equa- 

 tions for exhibiting the relations of goniomelrieal lines, from 

 whence a multitude of curious theorems may be derived.

GONIIIM, in Zoology, a genus of Vermes, charaftcrizcd 

 only by their very hmple, flat, and angular form, and be- 

 ing iuvifible to the naked eye. The fpccies at prefent 

 known are few, amounting to no more than ilve in num- 

 ber ; and for the cxiilencc of thefe we rely chiefly on the 

 niicrofcopical refearches of MuUer and Scliranck, the 

 fcn-mer of whom defcribes four of thefe minute creatures 

 with great accuracy in his " Zoologia Dauica." They an 

 molUy inhabitants of frefh or pure water, thouj 

 them occur in ilagnant water or in dunghills.
