Binary Canon.—Report of the Committee, consisting of Lt.-Col. 
ALLAN CUNNINGHAM, R.E. (Chairman), Prof. A. E. H. Love 
(Secretary), and Major P. A. MacMaunon, appointed for 
Disposing of Copies of the Binary Canon by presentation to 
Mathematical Societies. 
THe Committee have sent out fifty-eight copies of the above work 
to representative Mathematical Societies at home and abroad (thirteen 
and forty-five respectively) at a cost of 41. 9s., as per enclosed account, 
and return now the unexpended balance of eleven shillings. 
Dynamic Isomerism.—Report of the Committee, consisting of

(Secretary), Professor SypNEY Youne, Dr. C. H. Derscu, 
Dr. J. J. Doppiz, and Dr. M. O. Forster. (Drawn up by 
the Secretary.) 
Anomalous Rotatory Dispersion. 
Durine the year much justification has been found for the view 
expressed in the Report presented at Birmingham ‘ that a knowledge 
of the phenomena of dynamic isomerism is essential for the interpreta- 
tion of optical rotation, especially in the case of liquids which show 
anomalous rotatory dispersion,’ and that ‘the study of rotatory
