 and hardnefs much like a Pebble, and of colour yellowifi-. divi- 

 ded firft by five pretty ftraight lines, adorned on each fide with 

 double fets of points, afcending from a protuberant umbilicus in 

 the bafts of the /lone, to another of like form at the top, but fo- 

 liatedround in manner of a Rofe : And after again fubdivided by 

 five other indented lines, terminated before they reach the umbi* 

 lid ; by which means the fpaces between thefe lines are all penta-
