Deposits containing Fossil Plants. 89 



The upper part of Preglacial Cromer Forest-bed is here 

 a bed of blue lacustrine clay, full of freshwater shells and 

 seeds of aquatic and marsh plants. Dry-soil species and 

 forest trees are absent. Among the plants are Trapa 

 natans and Stratiotes aloides. 



SlLCHESTER ROMAN STATION, HAMPSHIRE. 



(Hope and Fox, ' Excavations on the site of the Roman 

 City at Silchester, Hants, in 1890-1897,' A re hceologia, Vols. 

 L.-LVII. 1891-1898.) 



Some material sent to me in April of the present year 

 (1899) by Mr. A. H. Lyell, from one of the excavations 

 made to explore this station, contained a number of seeds 

 which belong to the date of the Roman occupation. They 

 do not include cultivated plants of any sort, with the 

 doubtful exception of a single capsule of flax ; but among 

 them are several weeds of cultivation, the seeds of which 

 are small and starved, as though growing on exhausted 

 land that for some years had been out of cultivation or 

 occupation.
