386 REPORT—1868. 
still very doubtful. The apparent paths of the meteors 8, 9, 10, as recorded 
at Birmingham, require to be prolonged towards the points of disappearance, 
and to be shortened at the points of first appearance, while opposite correc- 
tions nearly equal in amount (about 8°) require to be applied to the apparent 
paths observed at Winchfield, in order to satisfy the conditions of simul- 
taneous observation. The discrepancy of the observations in each case would 
be explained by supposing those at Birmingham to have reference to an early 
view, and those at Winchfield to refer to a view of a somewhat later portion 
of the visible path of the same meteor. 
The direction of the meteor No. 11 relatively to the two stations is not 
favourable for very exact determinations of its height, which are, accord- 
ingly, affected by probable errors of many miles for 1° of error in the observa- 
tions. The same probable error in the other meteors of the list does not, in 
any case, exceed 2 or 3 miles.

(c) Heights and other particulars of the August meteors in 1866, by Pro- 
fessor Heis (Astronomische Nachrichten, July 1867). 
The meteors were most abundant on the nights of the 9th, 10th, and 
11th ; and the position of the radiant-point appeared to vary on successive 
nights between H. Camelopardi and y Persei. The following heights of me- 
teors were observed at Blumenthal (B.) and Leer (Le.).

* The apparent point of disappearance is regarded as correctly observed at Pekeloh by 
Height in B. 8. 
Dr. Heis, and at Gottingen by M. Borgen; the apparent flight having been recorded as 
much longer at the former place than at the latter. The great discrepancy of the heights 
of a meteor, so differently inferred by different computers from the same observations, 
may, in this way, frequently be accounted for.
