nually chang’d by a kind of flu€tuating motion, not unlike that of the 
waves of the Sea; foas that part of the limb, which was but even now 
nick’d or indented in; is now protuberant, and will prefently be finking 
again ; neither is this all,but the whole body of the Luminaries, do inthe 
Tele(cope, feem to be deprefs'd and flatted, the upper,and more efpecially 
the under fide appearing neerer to the middle then really they are,and the 
right and left appearing more remote:whence the whole Area feems to be 
terminated by a kind of Oval.It is further obferv d,that the body,for the 
moft part, appearsred, or of fome colour approaching neer unto it, as

\ limb isflatted or ovalled,the more red does the body appear, though not 
"always the contrary. It is further obfervable, that both fix'd Stars and 
Planets, ithe neerer they appear to the Horizon, the more red and: dull 
they look, and the more they are obferv'd to twinkle; in fo much, that 
I have feen the Dog-ftarr to vibrate fo {trong and. bright a radiation of

{tis alfo-obfervable,that-thofe bright {cintillations neer the Horizon, are 
not by much fo quick and fudden in their confecutions of one another, as

- that the Starrsneerthe Horizon, are twinkled with feveral colours; fo as 
fometimes to appear red,fometimes more yellow,and fometimes blue,and 
this whenthe Starr is a pretty way elevated above the Horizon. Thave —
