Practice. Make ac equal to 4%, and bifeQ acin 6; 
whereon, with the Diftance a4, defcribe the Semicircle adc ; 
On a, with the Interval ac, defcribe the Arch ce, and with the

pleting the Ova/ required. Q, E. F. 
NN. B. That the Figure thus defcrib’d, is vulgarly called an 
Egg Oval, tho’ in Ae. it is not; becaufe the Arches ce and 
af interfeét each other, and conftitute an Angle at g, which is 
contrary to the Curvature of an Ellipfis. Therefore to defcribe 
an actual Egg Oval, proceed as follows, vzz. Having defcri- 
bed the Figure according to the preceding Way, draw the Line 
6g; which divide in/. On / with the Opening /g, defcribe the 
Arch 0g, andon g the Arch p/&, interfetting the former in 
ry and 2 Laftly draw /2, cutting the Arch ce in m, /r cut- 
ting the Arch af in s, and on J, with the Opening /m, defcribe 
the Arch #25, which will complete the true Egg Ova/, as re- 
quired. | .
