Ordinary Meeting, October 22nd, 1900. 



Charles Bailey, F.L.S., President of the Section, in the Chair. 



Mr. H. Hyde exhibited a portion of a sunflower in fruit, and 

 drew attention to the extreme symmetry and regularity of the 

 seeds. Mr. MelviU mentioned the probability of the sunflower 

 becoming of great economic value, owing to the seeds containing 

 an oil, which may be used in the manufacture of soap, so that 

 the cultivation of the sunflower on a large scale, for industrial 

 purposes, may be one of the possibilities of the future. 



Mr. Rogers exhibited a collection of shells recently received 

 from Australia. 



Mr. Stirrup read a paper endtled " Examples of the genus 

 Cerithiuvi from the tertiary deposits of the Paris basin." 

 Specimens of the genus, collected on a visit to Grignon 

 arranged by the International Congress of Geology in the past 

 summer, were shown, together with examples from numerous 

 localities lent by Mr. Melvill.
