Upon tkis list a gentleman who has made the ti'ibe a special study, 

 John Abercrojibie, Esq., M.D., of Cheltenham, has favoured us wiLh 

 the foUomng liighly interesting remarks : — " This list is most extremely 

 interesting as presenting four species of the genus Jihajjhoneis, which is 

 not mentioned at all in Smith as a British genus, with the exception of 

 Amphora as a synonym for Doryphora. Of the four named, three are 

 American and one Antarctic, according to Ehrenberg — of the three Ameri- 

 can two are fossil, — so that if these are aU now living in the estuary of the 

 Severn, it is a most interesting circumstance, and one quite worthy to be 

 made moi-e generally known. The specimens of Dictyophyton fcEiii- 

 culatum mentioned as growing upon the Silurian rocks proved to be 

 completely covered with the frustules of Cocconeis scutatum. 



Pondering upon the incidents of the day, not, we feel, ill-spent, 

 we make our way to the canal bank at Frampton, passing the 

 brick-pits, which afford, amongst the bulnishes and other water plants 

 which fringe their sides, a secure asylirm to many coots and water hens, 

 and, passing thi'ough the churchyard and pretty village, with its spacious 

 green, and memories of Fair Rosamond, of which foremost comes 

 to mind a scrap of her epitaph — 



Non redolet sed olet quid prius redolere solet, 

 we take brief rest, and light refi-eshment, witli mine host of the Bell, 

 as we have stiU a walk of nine miles before us. Thence to Whitminster, 

 again tlirough a churchyard, glancing rapidly over gi-avestones inscribed 

 with many familiar namea One of these, over all that was mortal 

 of a philanthropist, well known in his day, and still remembered by all 

 who knew him with respect and honour, revives those feelings in us
