Original copies in printed paper covers are filmed beginning with the front cover and ending on the last page with a printed or illustrated impres- sion, or the back cover when appropriate. All other original copies are filmed beginning on the first page with a printed or illustrated impres- sion, and ending on the last page with a printed or illustrated impression. The last recorded frame on each microfiche shall contain the symbol — ♦- (meaning "CON- TINUED"), or the symbol V (meaning "END"), whichever applies. L'exomplaire fiimd fut reproduit grace i la g6n6rositd de: Ecole polytechnique, Universite de Montreal, Bibl iotheque Les images suivantos ont 6i6 reproduces avec le plus grand soin. compte tenu de la condition et de la nertet6 de I'exemplaire fiimd, et en conformity avec les conditions du contrat de filmage. Les exemplaires originaux dont la couverture en papier est imprimAe sont film6s en commencant par le premier plat et en terminant soit par la dernidre page qui comporte une empreinte d'impression ou d'illustration. soit par le second plat, selon le cas. Tous les autres exemplaires originaux sont film*ri en commenpant par la premidre page qui comporte une empreinte d'impression ou d'illu-tration et en terminant par la dernidre page qui comporte une telle empreinte. Un des symboles suivants apparaitra sur la derniire image de chaque microfiche, selon le cas: le symbole — »- signifie "A SUIVRE". le symbole V signifie "FIN". Maps, plates, charts, etc.. may be filmed at different reduction ratios. Those too large to be entirely included in one exposure are filmed beginning in the upper left hand corner, left to right and top to bottom, as many frames as required. The following diagrams illustrate the method: Los cartes, planches, tableaux, etc.. peuvent etre film^s i des taux de reduction diff^rents. Lorsqua le document est trop grand pour etre reproduit en un seul clich6. il est film6 A partir do Tangle sup6rieur gauche, de gauche i droite, et de haut en bas. en prenant le nombre d'images n6cessairo.

It. CANNON, M.A. Sixty-one plates of this star (a = 14'' :}7™-S, 5=-')° i;j'-4) were taken here, lifty in the years 1<»1;? and 1914, and eleven in 1010. These latter were taken close together to test for a short period. Ten measures were published in L.O.B. 199, which are given in Table I. The total range in the ten plates was 19 km., a rather small range to work on with our dispersion, but it was thought that a greater range might appear. The type is F,"), and magnitude 4-0. The earlier plates were measured by Mr. Parlcer, who was working on the star at that time. The measures are now published because it is hardly probable that an orbit could be obtained with the present equipment, and, indeed, doubtful from our results if the star is a binary. There is the jjossibility that it may be a binary with a long period. The measures of 1918 and 1910 seem to be generally more positive than those of 1914. The thirty-one plates of 1913 give a mean of +8-9; nineteen taken in 1914, a mean of 4-2 -S: and eleven in 1916, a mean of -f 7-7. It would be necessary to continue for some years and take a considerable number of plates each year to make sure of tins.
