Church-windows made at Cafaick. in Saxony, and Merfeb'urg in 

 Thuringia, which certainly mnft be of a different fort, from what 

 is defcribed by Aldrovandm c and Wormiws d : the one whereof 

 fays 'tis imbrium impatiens ; and the other, humido corruptibilis; I 

 expofed this of ours many rainy days, but could not find that

 ply the defecls of other Authors, whofe defcriptions df it are 

 but mean andimperfeft. 



16. After the Moon-Jione, the Ail eriae, or Star- ftones, next 

 offer themfelves to our confideration, which, to avoid the con- 

 fufion of other Authors, I (hall only call thofe, whofe whole 

 Bodies make the form of a Star, as inTab. 2. Fig. 2,3, in oppo- 

 fition to the Aflroites, which in the whole are irregular, but a-
