To find the fitperficial Content of an Oval 



, The common Way is to multiply the long 

 Diameter by the fhorter, and from that Pro- 

 dud to extrad: the Square-Root, which you 

 rnay calla mean Diameter, and then, as if 

 you were meafuring a Circle, fay. 



As 14 is to II, fo s the mean D ameter to 

 the Content of the Oval ^ but this is not ex- 

 acl. A better Way is i . 27, that as i f|-r is 

 to the Length of the Oval, fo is the Breadth 

 to the Content thereof. We may go nearer, 

 by making the Fraftion larger, and f^y, as 

 1.273:24 is to the Length, fo is the Bread^-h to 

 the Content: Bur the tirft is near enough 

 to pur Purpofe in G^rdeniig. 



Let an Oval, then, be 50 Foot long, and 

 the Breadth, or ftiorteft Diameter, be 37. Say 

 as follows : 



As 1.27 is to 50 fo is 37 to the Content;
