 to the Observation of mathematical meii: which is, thal in Fe-

 evcning, when the Twiüght hath almost deserled the huiizon, 

 you shal see a plainly discernable way of the Twilight striking 

 up toward the Pleiades, and seeming almost to touch them. It 

 is so observed any clear night, but it is best illac nocte. There 

 is no such way to be observed at any othcr time of the year 

 (that 1 can perceive), nor any other way at that lime lo be 

 perceived darting up elsewherc. And 1 believe il halb been, and 

 will be constantly visible at that time of the year. Üut what 

 the cause of it in nature should be, I cannot yet imagine, but
