_ May 18.—Very bright; kidney shaped, shewing sectors, somewhat similar to Halley's Comet 
in 1835. 
May 20.—About as bright as the Nebula in Andromeda. 
May 29.—Comet well shewn. 
June 1.—Comet barely visible. 
June 3.—Comet and star both very faint. The place of the compared star is determined on 
the supposition that 6 55™ 575.3 in the Histoire Celeste, should be 6" 57™ 57®.3. 
Four stars visible.
