The Implantation of Additional Hypophyseal Rudiments in Urodele Embryos.

Conclusions.-A method of resolution of tertiary carbinols of the aromatic series containing an asymmetric carbon atom has been described by means of which an optically active derivative of phenylbiphenyl-anaphthyl carbinol has been prepared. Investigations are now in progress with a view of converting this compound into an optically active triarylmethyl. The results of these experiments will be reported at a later date and should be of interest not only in connection with the Beckmann rearrangement but also should contribute further valuable information on such important questions as the Walden Inversion and the constitution of the triaryl methyls in general. 1 Jones and Walfis, J.
