APPENDIX E CV 
Geodetic lines and certain other curves drawn on the surface were 
also discussed from an elementary point of view. 
6.—“ Errors in Field Observations,’ by F. A. McDiarmid, discussed 
the errors of time, latitude and azimuth observations and showed 
the sources of these errors. 
7.—“Absolute and Relative Motion: The Relativity Principle,’ by 
R. M. Stewart, was a discussion of the optical problems arising 
from the motion of the earth relative to the luminiferous ether. 
The paper traced the difficulties arising in the attempt to har- 
monize the theory of the aberration of light with other optical 
phenomena, and explained the revolutionary character of the so- 
called “Principle of Relativity,’ which has been advanced to cor- 
relate the previously conflicting facts of experiment. 
8.—“ Personal Errors of Bisection in Meridian Circle Work,” by D. B. 
Nugent, will deal with personal errors in the bisection of stars as 
shown by the results of transit work with the meridian circle at 
the Dominion Observatory during the year, 1910. Their relation 
to the magnitude and to the declination of stars observed will also 
be discussed. 
9.—“ Errors in the Measurement of Spectral Line Displacements,” by 
R. E. DeLury, will discuss this subject in connection with certain 
solar problems. 
The following officers were elected at the Annual Meeting in 
December, 1910, for the ensuing year: 
President.—J. 8. Plaskett, B.A., F.R.A.S.C., F_R.S.C. 
Vice-President.—R. M. Stewart, M.A., F.R.A.S.C. 
Secretary.—Carl Engler, B.A., D.L.S. 
Treasurer.—C. C. Smith, B.A., D.L.S. 
Council.—J. J. McArthur, D.L.S., F. A. McDiarmid, B.A., W. E. 
Harper, M.A. 
XI.—Report of the Natural History Society of New Brunswick. 
Presented by Mr. W. J. Wizsow, Delegate. 
Mr. President, Ladies and Gentlemen: 
I have been requested to act as delegate of this Society, but as 
the report of the Society’s work has not yet come to hand. I can at pre- 
sent give but a brief outline of its work during the past year, to be 
supplemented by a fuller statement when the necessary papers and 
publications are received. 4 
The scientific work of the Society in the way of papers printed 
and read was largely of a special nature, being devoted to a description
