THE ORBIT OF COMET 1886 (FINLAY). 

 By W. H. Finlay, M.A., F.R.A.S. 



[Read 24th November, 1886.] 



I discovered this comet on the evening of September 26. After- 

 computing several parabolic orbits which failed to satisfy further 

 observations, I calculated the following elliptic elements from my 

 observations on September 29, October 10 and October 21.

It is not improbable that the Comet is identical with the first of 



1844, the "lost de-Vico."
