and fmall, and clear as Chryftall; whereas the other fi- 
gures were obfcure, as if they had been ftrowed wifh 
blackifti Sandi and fo likewife were thefe, when they 
were viewed with a better Glafs. 
I faw alio figures which were broad in the Middle, and 
fliarp at both ends-, or rather a little flat as E. Alfo
