Observatious of Meteors made at the Cambridge Observatory between No- 

 vember 13th, 11" 30'" and November 13th, 14" 15"', in the year 1866. By 

 Professor Ch.\llis. 



The observations were made by means of a small wooden meteoroscope on a tripod 

 stand, furnished with a straight bar about 21 inches long, and readily moveable in 

 altitude and azimuth. The mo-\euieut in altitude carried a graduated arc which 

 was read off by an index partaking- of the azimuth motion. The movement in 

 azimuth canied a horizontal graduated circle read oil' by an index fixed to the tiipod 

 stand. I marked the Hues of graduation roughly to integi-al degi-ees for use on this 

 occasion. In taking an observation, the bai- was pointed by hand to the place of 

 the meteor, the eye looking along the sti-aight edge. The point selected for obser- 

 vation was sometimes the middle of the course, but more generally the end of it. 

 At the instant of seeing the meteor I called out "now," and Mr. Todd, the Junior 

 Assistant at the Observatory, gave the time from a mean-time chronometer from 

 which he was ccunting to himself I then took the altitude- and azimuth-readings,
