be well heeded, when the like Meteor fhall appear , whether 
the perpendicular Fillet be not narrower where it paffeth through 
the Moon 5 than in other places, and efpecially upwards, 
where it muft grow larger and dif-appear, 
^ T:hat befides the perpendicular Cylinders , and thofe that are 
couched parallel to the Horizon, there are often a great ma- 
ny, which move to and fro in the Air in all forts of poficionsj 
and thofe, by the fame reafon that the round Grains do^ 
muft produce an H/^/^ about the Sun, and even a more vivid one 
than that which is caufed by the Grains , forafmuch as each 
Cylinder fends many more rays to the Eye, than each of thefc 
little Spheres. T^^ahe little Halo D EF, in the Roman Ph;e- 
nomenon( lig. V. ) may very well have been caufed by fuch 
Cylinders 
As to thofe .Mock' funs , ^hicH fometimes fhow themfelves

by M. H^vetim , and obferved Febr. 23. 1661 -) that he 
could find nothing neither in the round Grains nor in the Cy- 
linders ^ which fliould make thefc Suns necedarily to meet in 
tfiegreat VVfhite Circle, para-IIel tp the Horifoa^ znithat^ii 
that fliould be always verifyed by future Obfervations, the caufe. 
of it muftbe lookt for clfewhere: But that in themeantime 
he did believe , that that hapned not but by chance which 
beingTo , a reafon might be given of thefe Suns by the fame 
fuppoficion , which ' erved alfo for the Anthdion , obferved by 
M. Heuelim Sen. 6. 1661-, in which there were two colou- 
red Arche?» of a Circle 5 oppofite to thc Son^ which did in- 
lerfed one another , their interfedion being the place of the 
Falfe Sun. Which although it be teprefented in the Figare of 
Heveltm at the fame height with the true Sun, yet it was m 
truch higher by i5degrees or more^ ashe hath acknowledg- 
ed himfelf afterwards : Sothat^if there had been a great white 
G\xQ\t\vit\\\s Fhmomemn , the Parhdion was not at all to have 
been in it. 
That for the generation of thefe Suns, he did fuppofe a nam-^

which were carried in the Air neither perpendicubrly, nor cou-
