Transit of Venus, Dec. 6, 1882.— Report of Observations at Ottawa. 
By ¥. L. BLAKE, D.LS. 
[Communicated by C. Carpmael, M. A.] 
(Abstract.) 
I was assisted in these observations by Mr. B. C. Webber of the Meteorological Service, 
and the following instruments were used :—a four inch achromatic telescope, alt-azimuth 
mounting, a Transit instrument, by Messrs. Troughton & Simms, 23 inch O. G., and chro- 
nometer, Frodsham, 1752. ; 
The temporary observatory was erected on Nepean Point, in Latitude 45° 26’ N., and 
Longitude 5" 2" 48° W., approximate geographical positions. 
On the evening of the 5th, exchanged time with the Toronto observatory. The weather 
was very cloudy and threatening to snow. The morning of the 6th broke out with dense 
clouds at low elevation, with no immediate prospect of breaking. Soon after eight o’clock 
signs of clouds dispersing in 8. E. At 8" 15" by chronometer sun shone out brilliantly. 
Sighted on the sun and focussed on sun spots at 8" 24" ; rice grains on sun just discernible. 
Definition of telescope very fine.
