Discussion. 



The Chairman (Dr. A. Strahan) congratulated the Authoress 

 upon her discovery of this plant-bed at Brora, which was not only 

 interesting in itself, but important as affording further evidence 

 for the correlation of the rocks of Brora with those of the Yorkshire 

 coast. 



Prof. E. J. Garwood regretted that he could add nothing to the 

 discussion on the subject of this paper. He would, however, like 

 to take this opportunity of welcoming this first communication 

 from his old pupil, the distinguished Authoress. As many of the 

 Fellows knew, Miss Stopes had interested herself for some time in 

 paleobotany, and had just received from the Royal Society a sub- 

 stantial grant to enable her to visit the deposits containing coal- 

 balls in Japan. He felt sure that the Fellows of the Society would 

 join him in wishing every success to her expedition, and would 

 welcome future communications from her after her return.
