071 a new Divifion of the Compaf for Land Surveying, 



X HE prefent divifion of the compafs into degrees, &c. 

 originally intended for the convenience of the navigator, is 

 not neceflary for the land furveyor. To him a divifion w^hich 

 would give by infpedlion .the fine and cofine of the angle 

 EQeafured would be of much greater importance. Such a divi- 

 fion would preclude the neceffity of having recourfe to a table 

 of natural fines, and very often give the fine or cofine accu- 

 rately in only two or three places of figures, which would be 

 of confiderable ufe in facilitating the computation of great 

 furveys. This divifion might be accomplifhed with the fame 

 eafe to the ii;i{lrument-maker as the prefent one, and would in 

 every cafe afford equal if not greater accuracy in the refult.
