ORBIT ELEMENTS OF COMET f 1896 (PERRINE). 85 
These two normals were computed, anticipating that observa- 
tions would be obtained during the month of June 1897, but as 
previously mentioned this was impossible. 
To complete the necessary data, an observation has been 
employed, that was taken by Mr. Tebbutt on the date 1897 
April 19°89 Greenwich mean time, this position being adopted, 
as the astronomer noted that the star, from which the differential 
measure was taken, is a good one.
