Mr. P. E. Chase related his observations of the same 

 meteoric display, made at Haverford College, eight and a 

 half miles west of Philadelphia, viz. : 



Prof. Gummerc organized a corps of students, who com- 

 menced their watch on the evening of the 13th, at half-past 

 10 o'clock. When I went upon the field, about 2h. 30m. a.m., 

 I found that nearly 150 meteors had been seen during the 

 previous four h':^urs. They continued to fall at a slowl}'' in- 

 creasing rate until 3h. 30m., a large proportion being of more 

 than usual brilliancy, and nearly all radiating from the con- 

 stellation Leo. The increase then became more rapid; by 

 4h. more than 700 had been seen, and a few minutes later 

 the flight was so continuous that the count exceeded 1000, 

 and all further attempts at registering ceased. The display 

 reached its maximum about 4h. 25m., when, with Leo in the 

 centre of my field of vision, I counted 140 in a single minute. 

 There were then evidently many more in the eastern than in 

 the western portions of the heavens, and I judged that I 

 could see at least a third of the whole number that were 

 visible at the time. At 4h. 30m. a remarkable meteor started 

 from Regulus, moving southwesterly, and leaving a very per- 

 sistent train. After some seconds, two or three of the com- 

 pany took out their watches, and the train remained visible 

 for more than three minutes, slowly rotating through a full 

 quarter revolution before disappearing. It gradually curved 

 while rotating, and just before vanishing it represented an 

 arc of about 120°, looking like a wisp of fleecy cloud. This 

 seemed to indicate a complete revolution, in about 15 minutes, 

 of that portion of the meteoric atmosphere from which the 

 tail was thrown off". 



Mr. Marsh observed the same phenomenon at Germantown, 

 six miles north of this city, and gave an account of the prom- 

 inent characteristics as noticed by him. 



Prof. Kendall gave an account of the observations made 

 by himself and a number of his students, at the University 

 of Pennsylvania, in Philadelphia. 



Mr. Fraley called the attention of the Society to a model, 

 now on exhibition in this city, aiFording a complete represen-
