PROCEEDINGS OF SECTION A. 51 



The importance of taking advantage of the first opportunity of 

 determining the difference of longitude between Canada and Australia 

 along this route was quickly recognised by the Canadian astronomers 

 who, having previously established a chain of longitudes across the 

 Atlantic between Greenwich and Canada, could now continue the chain 

 to Australia to meet the other end of the chain carried eastward 

 from Greenwich, thus closing a complete longitude circle round 

 the Earth. 



The Government of Canada having authorized the work, Dr. Otto 

 Klotz, of the Ottawa Observatory, with his Assistant, Mr. F. W. 0. 

 Werry, B.A., commenced operations in March, 1903, and concluded 

 his great series of Transpacific Longitudes in January, 1904. 



The results obtained by Dr. Klotz are as follow (*), page 197 : —

The Longitude of Vancouver is based on the three arcs — 

 Greenwich-Montreal, determined in 1892 by Prof. Turner and 

 Mr. Hollis of Greenwich Observatory, and Prof. McLeod, of 

 Montreal (f) McGill College Observatory. 

 Montreal- Ottawa, by Dr. King and Prof. McLeod, in 1896 (*) ; 

 Ottawa- Vancouver, by Dr. King and Dr. Klotz, in 1900 (*) ; 

 the respective values being —
