"McGiLL College Observatory, Montreal, May 26th, 1892. 

 " Dr. J. G. Bourinot, C.M.G., Vice-President of the Boyal Society of Canada. 



"Dear Sir, — Replying to your inquiry as to the condition of the Montreal-Greenwich longitude 

 determination, I beg to say that the work began on April Gth has continued to this date, and that 

 one-half of the necessary observations have been made. The English observers engaged in the work 

 are Mr. H. II. Turner, chief assistant to the Astronomer Royal, and Mr. Hollis, assistant in the Royal 

 Observatory. Through the courtesy of the Surveyor-General and the Department of the Interior, 

 Ml'. O. J. Klotz, D.L.S., has taken part with me as the second Canadian observer. 



" Observations having been made at Montreal and Greenwich for the determination of the personal 

 equation of the Canadian and English observers resi^ectively Mr. Turner occupied the Irish station 

 (Waterville), and I that at the Canadian end of the cable (Canso, liova Scotia). We then decided 

 finally upon the methods of transmission through the cable. The first astronomical observations were 

 made on April 19th, and the observations of the first stage continued until April 27th. Mr. Turner 

 then returned to Greenwich and I to Montreal to cari-y out the observations of the second stage. 

 These were commenced on May 4th, Messrs. Hollis and Klotz, occuping the stations at Waterville and 

 Canso, respectively. These observations were completed on the 18th instant, and Mr. Klotz has 

 returned to Montreal, where he will again observe with me for personal equation, the English 

 observers doing similar work at Greenwich. 



" I am to sail for England on .Tune 25th, and will observe with the English observers at Greenwich 

 during the month of July. About August 1st Mr. Turner is to leave for Canada, and will alternately 

 with Mr. Klotz occupy the stations in Canada, while the Irish and English stations will be occupied 

 by Mr. Hollis and mj'self.

" I can only add that up to the present the work has gone forward in the most successful manner, 

 and express my deep appreciation of the great kindness and assistance of Mr. S. S. Dickenson, Super- 

 intendent of the Comnxercial Company's Cable station at Canso, and of his Chief Assistant, Mr. Upham. 



" Yours very truly, 



"C. H. McLeod." 



It is now eleven years since the Society held its first general meeting at Ottawa and ten years 

 since the publication of the first volume of the Transactions and Proceedings through the libei-ality 

 of the government of Canada. It is now a matter worthy of the deliberate attention of the Society
