planet’s egress, and although the limbs of both the sun and 
the planet were rather tremulous, yet satisfactory observa- 
tions of the times of internal and external contact were made- 
The telescope used was the equatorially mounted achromatic 
of five inches aperture, with a positive eyepiece having a mag- 
nifying power of 126. The times of internal and external 
contact were : 
d. h. m. s. 
Internal contact at Egress... Nov. 4 — 21 0 7'3 G.M.T. 
External contact at Egress. .. ,, — 21 2 38 - 8 „ 
At the time of internal contact the disruption of the 
thread of light between the planet and the sun’s limb 
occurred instantaneously through a considerable portion of 
its length, thus producing a momentary impression that the 
limb of the planet had suddenly altered its form. Beyond 
this no phenomenon of an unusual or abnormal character 
was observed.

Ardwick. 
The morning was very unfavourable for continuous 
observation, clouds obscuring the sun until 8h. 20m. when 
it became visible for a few minutes only. It then remained 
covered with dense clouds accompanied by rain until 8h. 55m. 
when it suddenly re-appeared, and continued moderately 
free from clouds until after Mercury passed off the disc. 
The large equatorial was dismounted, and I was therefore 
obliged to observe with a three-inch object glass with a 
power of 60. Mercury was very black and well defined, 
but owing to the small diameter of the telescope I do not 
attach much value to the time of external contact with the 
sun’s limb, which appeared to take place at 21h, 2m. 19s. 
G.M.T. No elongation was noticed.
