THE HAMILTON ASSOCIATION. 63- 
is now nearing completion. ‘The following Observatories were 
engaged in the task, viz.: Heisingfors, Potsdam, Oxford, Green- 
wich, Paris, Vienna, Bordeaux, Toulouse, Catane, Algiers, 
San Fernando, Chapultepec, Tacubaya, Rio de Janeiro, 
Santiago, Sydney, Cape of Good Hope, La Plata, and 
Melbourne. In order to obtain uniform results from all parts 
and Melbourne. In order to obtain uniform results from all parts 
of the globe the telescopes employed were all refractors of 11 
inches aperture and 11 feet focal length, giving a field of view 
of 2 degrees square. The necessary instruments have been pro- 
vided at the expense of the Governments represented, and cost 
about $7,000 each. Mr. Jenkins here traced the progress of 
celestial photography from the time Dr. J. W. Draper first photo- 
graphed the moon in the year 1840 to the products of the leading 
Observatories of to-day. 
A visit to the Toronto Observatory brought the address to a 
close. This institution was principally known for the valuable 
magnetic observations which had been conducted there for the 
last 65 years. The first Observatory was constructed of logs, 
but for many years the work had been carried on in a suitable 
stone building in Queen’s Park. It contained a fine 6-inch tele- 
scope by Cooke, of York. This instrument was most substantially 
mounted on a clock driven equatorial, and daily observations of 
the sun were made by the same. Owing to the advent of the 
electric cars into Toronto in the year 1892, the magnetic instru- 
ments had to be removed to the village of Agincourt, 18 miles 
away. The Dominion Government had now erected a handsome 
Observatory in Ottawa and installed a large 15-inch telescope by 
Brashear. It was under the direction of Dr. W. F. King, Chief 
Astronomer of Canada, and the whole of the Toronto equipment 
was being transferred to Ottawa. 
In conclusion, Mr. Jenkins said, lest the size of the telescopes 
in these great public Observatories should deter anyone from the 
thought of taking up the study of astronomy, and perhaps even 
of joining a body like thé Hamilton Astronomical Society, he 
would remind them of Sir Robert Ball’s words: ‘‘The student of
