142 Mr. Schroeter's new Observations 
which shewed me clearly that the smaller form of the right 
side, according to fig. 15, was occasioned by the boundary of 
light running in a little more at the right horn. 
6 h 25', I found this repeatedly confirmed with 370. 
At y h 5' to 10', this difference no longer struck my eye ; both 
horns appeared equally pointed. 
S h 24', the same with 160. Venus was no longer distinct. 
April 5th, 5* 15' p.m. Both horns indeed sharp, but all as it 
was the evening before, and nothing striking, with 160. 
5* 25', the same with 288. 
6 h 38 ', still the same. 
y h 38' to 8^ 10', with both magnifying powers, and after- 
wards with 136 of the 13-feet, no manner of inequality in the 
horns. With the greater telescope the decrease of the light to 
dimness, and the dim unevenness of the boundary of light , ap- 
peared extraordinarily fine. 
8* 42'. Both horns still equally pointed, with power 160 of 
the 7-feet. No spot. 
9 h 55' > the same. The planet being now as low as on 
the 2d and 3d of April about the same time, I tried, by screw- 
ing in various ways, whether 1 could get the southern horn to 
look somewhat rounded, as it did then, but in vain : both 
horns were equally pointed. 
April 6th, 6 h 45' p. m. with 160 of the 7-feet, I found no 
striking difference, both horns being equally pointed. No spot. 
7* 29', likewise so. 
8* 10', the same with power 288, and an extremely sharp 
image. 
8" 45', the same.
