Having taken the Plan of it on Paper, re- 

 duce it into Triangles, by drawing Lines 

 from one Length to another, and leaving no 

 irregular Square in the whole Work. Being 

 thus reduc'd into Triangles, you are to pitch 

 upon proper Lines for your Bafe ; fuch indeed 

 are^thofe that are oppofite to the wideft An- 

 gle, thc;n let drop, or you may from thence 

 fuppole a perpendicular Line 5 your Work 

 is juit ready to do as you did before, in the 

 Example of Triangles. 



There are fome that advife the dividing 

 and meafuring fuch Plats in the fame 

 Manner you would do a Trapezium ^ but 

 that is almoft the fame as this, tho* not 

 fo intelligible, nor indeed fo exacl^ I have 

 therefore chofe this Way, tho' it is fome- 

 thing more Trouble : Yet, where two Per- 

 pendiculars have one common Bafe, as have 

 the Divjfions b and c^ i and k^ h and <?, you 

 may add both Perpendiculars together, to 

 fave Trouble, and fet them down, as in the 

 Example, 



I need not farther repeat the Method of 

 taking, or cafting up the Dimenfions of this 

 irregular Plat ^ but, in order to find the Con- 

 tent of the whole Field, I fuppofe the feVeral 

 Dimenfions, upon ciafting up, are as follow:'^ •
