between the residuals from the hyperbolic and from the parabolic 
elements can be but y we ‘loss by any supposition of error in

In the Vierteljahrachrit “for 1881, Dr. Schonfeld discusses the 
memoir of Professor Beebe, oints out some corrections that 
should be made, aa expresses the belief that the original records 
of the observations are in existence, and can be used for the

On the 12th of October last, Professor Weiss communicated to 
the Vienna aonaaas the results of a new computation by Dr. 
Kreutz. In the notice in the Astronomische » Nacoviohies there is

this discussion shall be found to have covered the whole ground, 
and to have been in all ‘ioaiie satisfactory, it will be difficult to 
claim a hyperbolic orbit for any comet hitherto observed. From

near and behind some distarbing planet. But of course such con- 
Re must give way if there be any well-established instance 
of a y Laeiag? cometic orbit. H. A. Ni
