Abstract
RECENT work on optical rotatory power has directed attention to the importance of the phenomena which were observed in certain coloured tartrates by Cotton in 1896, namely: a maximum ellipticity and a zero rotation interposed between positive and negative maxima, giving rise to a loop in the region covered by an absorption band. Dr. Stotherd Mitchell's monograph is therefore very welcome, since it contains an attractive review both of the experimental work which preceded Cotton's observations and of subsequent experiments with other optically active compounds containing absorption bands of suitable wave-length and intensity.
