 true Algae in Palaeozoic strata, though he considers that most of the 

 forms described as such by Saporta have no claim to be included in 

 the vegetable kingdom. G. J. H. 



III. — On the Flora of the Cromer Forest-Bed. By Clement Beid, 

 F.G.S. Transactions of the Norfolk and Norwich Naturalists' 

 Society, vol. iv. pp. 189—200. 



EBOM various exposures of the so-called Cromer Forest-Bed at 

 different localities on the coast of Norfolk, and at Pakefield in 

 Suffolk, Mr. Beid procured samples of dark peaty sandy clays, which 

 by careful manipulation and washing, yielded the seeds and fruits of 

 a number of plants. These were patiently and carefully picked out 

 under a magnifying glass, classified, mounted, and then compared 

 with existing forms, with the results that the number of species in 

 the accompanying list is more than double that previously known. 

 The species of Mosses and Chara have not yet been determined, but 

 the list includes 40 species of Dicotyledons, 18 of Monocotyledons, 5 

 Gymnosperms, and 3 Cryptogams. With a few exceptions the same 

 plants still exist in the locality, but some are locally extinct. Mr. 

 Beid points out the significance of this fact, when it is considered 

 that since the period when the plants lived whose fruits and seeds 

 have been preserved, the Glacial epoch has intervened, and the large 

 mammals, and even many of the mollusca, have become extinct. So 

 far the investigations into the Bliocene Flora show that the period 

 of intense cold produced but little effect in the distribution of the 

 plants in this locality, since the same forms with few exceptions 

 returned, apparently without intermixture, to re-occupy their former 

 habitats. 



The paper is a brief one, but it represents a great amount of 

 steady, continuous work, and careful observation. It will prove of 

 much value, both from a botanical as well as a geological point of 

 view, and its importance is enhanced from the fact, that with one or 

 two unimportant exceptions, no Plant-remains are yet known from 

 other Pliocene beds in Britain. G. J. H.

N recent scientific history of civilization few administrative 

 events can compare in magnitude, or in their effects upon the 

 populations concerned, with the Geological Survey of the United 

 States. In no other part of the world have the resources of the 

 Government been used with a like wisdom and liberality in 

 accumulating and diffusing natural knowledge of the country, for
