The President thought that it must be a plant growing in the 

 interstices of the calcareous concretion. 



Mr. T. C. White inquired whether other plants in the neighbour- 

 hood were also incrusted. He thought this would be the case if the 

 water were highly charged with lime. 



The Secretary said that such would no doubt be the case ; indeed,

At the next meeting, on the 2nd of April, Mr. W. K. Parker, 

 V.P.R.M.S., will read a paper on " The Development of the Sturgeon's 

 Facial Arches," and Mr. Henry Davis will read one on " A new Calli- 

 dina : with the result of experiments on the Desiccation of Rotifers."
