THE ROYAL ASTRONOMICAL SOCIETY OF CANAD& Bulletin No. 1 INSTRUMENTATION SECTION At the Society's General Assembly in Winnipeg in May 1966, I had the honour of being appointed National Co-ordinator of the Instrumentation Section. To the best of my knowledge, this is a category; therefore, records or information as to type or numbers of instruments in use by members of the R.A.S.C. are not available. I would like to suggest that each Centre appoint a member to keep me infoiined of the type and number of instruments currently in use by their Centre. For a telescope, this should include the diameter of the objective or mirror and focal length; arty unusual features of a particular instrument should be given. Information should also be included on micrometers, spectroscopes, photometers, camera equipment, etc., sun-observing eqtdpnent such as spectroheliograph, spectrohelioscope, monochromator, etc., as well as instruments under construction. Very old instruments still in use are interesting, particularly if a short history is included. I hope to reeeive replies from all of our Centres. George R. Ball, National Co-ordinator, Instrumentation Section, Standing Committee on Observational Activities, 54 West Maddock Ave., September 21, 1966. Victoria, B.C.
