At 5* 45', the atmosphere being less clear, it was doubtful; 
and at 
6 h 35', it was quite certain that both horns appeared equally 
rounded, without any difference. I found neither spot nor 
glimmering. 
From the 6th to the 10th of March, the learned and worthy 
Dr. Chladni, inventor of the euphon, observed with me ; and 
having ascertained, by careful comparison, the extreme good- 
ness of my reflectors, can bear witness of it.
