S. Plaskett observatory director, who revealed some of the contributions made to the astronomicel science by the Canadian institution. Dr. Plaskett reviewed the history of research on this question, pointing out that for about 150 years, through observations of Sir William Herschel, it was supposed the luminous objects in point were of a gaseous nature. Sir William Huggins definitely proved this sixty years ins, do by examining them by means of the spectroscope, and thirty years later Barnard discovered that dark regions in photographs of the Milky Way which were assumed to be gaseous or meteoric matter cut off the light from distant stars. BLOCK LIGHT OF STARS While observation showed that these bright and dark nebulae occupied only a small fraction of the area of the sky research was turned upon the question as to whether gaseous matter was more widely distributed in the tremendous distances between stars of the galaxy. In 1904 Hartmann, at Potsdam, discovered through examination of the spectrum of the constellation Orion that two lines, indicating calcium, would not have come from the star itself but must have been caused through an intermediate cloud of calcium gas being absorbed Observations of Dr. Plaskett in 1923 revealed that the calcium lines were apparent in the spectra of the hottest stars in the Milky Way, indicating the gas was widely distributed through the galaxy. The gas appeared more or less stationary in the system and the stars were rushing through it. Dr. Plaskett devoted considerable attention to this theory. Professor Eddington in 1926 developed a theory on1 the basis of the Victoria observations. This set cut that the gaseous matters were exceedingly diffuse with a vacuum many millions of times greater than was obtainable on the earth. The gas must have an effective temperature of about 20,000 degrees and should be revealed by calcium lines in stars more than 800 light years away. Later observations by Dr. J. A. Pearce and Dr. Plaskett at the local observatory confirmed the theory that this gaseous matter was a distributed through the Milky Way and rotated along with the stars around a distant centre. In its revolutions the speed of the galaxy is about 200 miles second or 2.000 times faster than man has ever traveled on earth, the speaker sald. The system is so large, however, that It will take about 250.000,000 years to make a complete revolution. In extending thanks to Dr. Plaskett, the chairman commented that the data revealed in connection with these gaseous matters was one of the most important recent developments in the study of the universe and was mainly due to efforts at the observatory here.
