EARL ROSSE’S OBSERVATIONS ON THE NEBULiE. 
“December 14, 1848. — Note by Mr. Johnstone Stoney: — ‘Three stars near it, some- 
what in this fashion; showed it to Sir James South.’ 
“December 16, 1848. — Sketches made by Lord Rosse and Mr. Johnstone Stoney. 
“December 19, 1848. — Drawing confirmed.” 
Fig. H. 14, 2098. — “Observed October 23, 1848, and sketch made. 
“October 25, 1848. — Sketch confirmed. 
“August 16, 1849. — Position of ring taken with an eye-piece furnished with a level 
and a position circle. Inclination of ring to horizon 9°.” 
Fig. 15, H. 450. — “February 20, 1849. — Most astonishing. The star perhaps a 
little nearer the np edge. Drawing made ; breadth of ring less on f side. 
“February 22, 1849. — Observed again; dark space to the right of star. 
“January 16, 1850. — Observed; examined with the 700 and 900 eye-pieces ; both 
the dark and the bright rings seemed unequal in breadth ; the light appeared unsteady 
and flickering. The night was rather foggy, but the sky black.” 
Fig. 16, H. 361. — “January 28, 1849. — / Orionis. Dark space in the nebula con- 
taining nearest companion; light nearly equable; sketch made; 3-feet telescope 
employed. All the stars in the neighbourhood are nebulous, of these two a little sp, 
last seem to have dark spaces as in figure. To the nf oi this there is another smaller 
double star, suspected to have similar dark spaces to / Orionis. 
“February 16, 1849. — Three-feet telescope confirmed observation of January 28, 
1849. 
“March 17, 1849. — Large triple star to south of nebula Orionis; confirmed ob- 
servation of opening in its atmosphere, also the openings at double star sp last.” 
Fig. 17, IL 2060. — “Observed September 9, 1849. Drawing commenced. 
“September 16, 1849. — Drawing proceeded with ; examined also with 3-feet tele- 
scope to find if any evidence of change since drawing in Philosophical Transactions 
was taken ; none decisive.”
