ON THE METEOROLOGICAL OBSERVATORY, MONTREAL. 65 
Meteorological Observatory, Montreal.—Report of the Committee, con- 
sisting of Professor H. L. CALLENDAR (Chairman), Professor C. 
McLeop (Secretary), Professor ¥. Apams, and Mr. R. F. Stupart, 
appointed for the purpose of establishing « Meteorological Observatory 
on Mount Royal, Montreal, Canada. 
As reported last year, some very good records of temperature on the top 
of the mountain were obtained by means of a recorder set up in the 
College Observatory at the base, and connected by a line about a mile 
long to an electrical thermometer set up in the tower on the summit. 
Unfortunately, the grant for meteorological purposes had been reduced by 
the present Government, and the sum of money at the disposal of the 
Committee, amounting to only half the estimated cost, did not permit of 
protection for the line and the instruments in a sufficiently permanent 
manner. In the early part of the summer the lock was broken, and the 
instruments mischievously damaged. At a later date, the thermometer 
was struck by lightning, and the insulation of the line suffered. After 
some delay, owing to the winter, the cost of a new thermometer was 
defrayed by the Physics Building Committee, but it was found that the 
insulation of the line had deteriorated seriously in the course of the winter, 
and the accuracy of the records was considerably impaired. It is hoped 
that these defects will shortly be located and repaired, and that the 
apparatus will soon be in good working order. 
The Committee ask for reappointment, with a further grant of 20/. 
for the more efficient protection of the line and instruments.
