March 1st, 7Jh. Klein’s crater well seen with 4in. 
aperture. With Gin. aperture it appears smaller and much 
less dark than last night. At lOh. the crater is sensibly less 
dark since 7|h., and has now an irregular oval shape in the 
direction of the small crater No. 1. 
March 2nd, 6h. 35m. The crater no longer appears either 
as a round or oval shaped spot, but on its place and extend- 
ing nearly to the first or No. 1 small crater, to the S.W. 
there is a dusky marking but little less bright than the 
surrounding district. 7h. 15m. Definition has now become 
so bad that it is impossible to make out any of the details 
satisfactorily, or even to distinguish the dusky marking. 
March 3rd, 9h. 30m. Klein’s crater is not now visible as 
either a dark or a bright spot. 
March 4th, 9h. There is a moderately bright spot on or 
very near the place of the crater; it is less bright than either 
of the two small craters to the S.W. Images unsteady, and 
observation interrupted by clouds. 
March 5th, 12h. There is a faintly bright spot on the 
place of the new crater. The order of brightness of Nos. 
2, 3, 4 and N (the new crater) is 4, 3, 2, N. N appears to 
be elongated, or rudely shaped like the figure 8, in the 
direction of crater No. 1. 
March 6th, 7h. Klein’s crater is still visible, slightly 
brighter than the surrounding ground. Order of brightness 
—4, 3, 1 , 2 , N. 
March 8th, 12h. Klein’s crater and the other small craters 
very distinctly visible, definition being moderately good. 
Order of brightness— 4 = 3, 2, 1, N. A moderately bright 
streak from H to N with a faint continuation to a point on 
the furrow a little to the east of Hyginus. 
I have had no opportunity of observing the moon since 
the 8th of March, but the observations up to that date, as 
given above, seem to me to remove all doubt as to the 
existence of the object which Dr. Klein regards as a new
