satellite reached the limb it was as white as the 8d satellite, and 
rou e transit was made across the brightest part of the 
disc, and where there were no perceptible variations of brillianey. 
The 1st satellite’s last contact with limb was at 10" 2™ 47® 
1876, June 22.—Observations began at 10°12" p.m. The 
Ist satellite, known to be upon the disc, could not be found. 
The shadow was wholly on at 10°26" 56%. The satellite was 
seen, dusky, oval and gray, from 10" 55" 33° to 11" 10™ 33°. 
1877, June 13.—The shadow of the 2d satellite was seen, 
wholly entered upon the disc, at 11° 20" 45%. The satellite 
itself touched the limb at 11" 36™ 07°; was at internal contact 
at 11" 43™ 30°. 
1877, June 19.—The 8d satellite touched the limb of the 
lanet at 10° 47"58°. The internal contact was at 10" 59™ 10%. 
he 1st satellite reappeared from occultation at 11" 4™ 51%. 
The ruddiness of the equatorial belt was noticed by several 
observers.

antimony glance by means of hydrogen and his investigation 
was a model of its kind. In his paper* all the details of the 
experimental work are given and it is evident that every precau- 
tion was taken which the circumstances required. In 1857, 
this result was apparently closely confirmed by Dumas, whose 
analyses of antimonious chloride gave almost precisely 122. 
he present investigation was undertaken with the view of 
reconciling if possible the large discrepancy between the results 
suggested by the method, devised by the author, of precipitating 
sulphides which was described in a previous number of this
