Meteorological Observatory, Montreal. — Report of the Gommittee for the 

 Establishment of a Meteorological Observatory on the Top of Mount 

 Royal, Montreal, consisting of Professor H. L. Callendar (^Chair- 

 man), Professor C. H. McLeod (Secretary)^ Professor F. Adams, 

 and Mr. R. F. Stupart. 



The Committee desire this year to present an interim report, and to ask 

 for reappointment, with a fui'ther grant of 50^. The object of the 

 establishment of the observatory on the top of the mountain was to obtain 

 simultaneous records of temperature, humidity, ifec, for comparison with 

 those taken at the College Observatory at the foot. The distance between 

 the two stations is rather more than a mile, and the difference of altitude 

 nearly 600 feet. A line consisting of four insulated copper wires was 

 erected to connect the two observatories. As a preliminary experiment, 

 an electrical thermometer was set up on the Avooden tower on the summit 

 of the mountain, and connected through the line to a recording instrument 

 in the College Observatory. No difficulty was encountered in obtaining 

 continuous records of the temperature on the summit in this manner. It 

 is hoped that interesting results may be obtained by comparing continuous 

 records of temperature at stations differing so considerably in altitude 

 within a short distance of each other. The work has not yet progressed 

 for a sufficient length of time to enable ths Committee to report any 

 general results, but the success of the method has been established, and it 

 is intended, if possible, to further extend the method to the recording 

 continuously at a distance of wind velocity and direction, barometric 

 pressure, and humidity. The iiitensity of sunshine lias been i-ecorded for 

 some months at the observatory by means of similar instruments, and it 

 is hoped to demonstrate the possibility of obtaining complete and accurate 

 records of all necessary meteorological data from a distant observatory in 

 a more or less inaccessible situation (such as that on the summit of Ben 

 Nevis), without the necessity of employing a special observer to make 

 daily visits to the station.
