THE METEOROLOGICAL SERVICE OF CANADA. 
The matters of chiefest interest in the Meteorological Service during 
the past year have been a marked development of the synchronous 
weather chart, and the completion of the establishment of a Physics 
laboratory at the Central Office for the pursuance of research in at- 
mosphérie physics. 
The reports of observations used in the preparation of the daily 
weather chart are now supplemented by numerous reports from Europe 
and Asia, together with reports from Iceland, the Faroe Islands, the 
Shetland Islands, the Azores and various places in the West Indies; 
also from Honolulu and. Manila and from stations in Alaska and the 
Aleutian Islands. The Eastern hemisphere observations are taken 
at 7 o’clock Greenwich mean time or six hours earlier than those 
in America, but with the broad gap of the Atlantic lying between 
Europe and America this is seemingly of no importance, as due allow- 
ance can be made for changes occurring in the interval. 
This new field of observation promises to yield a harvest of infor- 
mation and usefulness, such as was unrecognized until the scheme 
became an accomplished fact. With a knowledge of the Meteorological 
conditions prevailing north of the British Isles and in Iceland, and also 
with a knowledge of the conditions in Alaska, it is found possible to 
deduce with surprising accuracy the conditions prevailing in the far 
northern portions of the Dominion, whence come the cold waves which 
in winter with varying frequency spread over the continent. 
The work of the physics branch proceeds satisfactorily. In con- 
nextion wih the exploration of the Upper Atmosphere 21 balloons 
carrying the Dines Meteorograph have been despatched and of these 12 
have been returned to the Central Office with good records. The heights 
reached varied between 6.3 and 12.6 miles and the isothermal layer 
was found at heights varying between 5.8 and 9.9 miles and with 
temperatures between —71° and —94° Fahrenheit. 
The following table gives the chief data obtained in the various 
ascents:
