Linaria purpurea ; also a Coronilla. Although the temperature of 

 Yarmouth appeared (felt) to us lower than that of lioudon by several 

 degrees, yet the growth of certain plants in the open air, or only slightly 

 protected, shows that the annual temperature is higher than that of 

 London. Fuchsias of immense size were quite common in almost 

 evei'y garden, as were also Hydrangeas and myrtles, both flowering 

 beautifully. We noticed Aloysia citriodora, the lemon-scented Ver- 

 bena, as it is commonly called, not much less than twenty feet high, 

 and of a moderate thickness : this plant was supported by a wall. 

 On the road from Yarmouth Ferry to Freshwater, Hypericum calyci- 

 uum was noticed in a copse, along with plenty of Rubia peregrina. 

 The latter plant is common in the hedges on the west side of the Yar. 

 Iris foetida [?] abounds between Yarmouth and Newtown ; and on 

 the coast in the same direction large specimens of Erythraeapulchella 

 occur, some of them not less than from eighteen inches to two feet 

 high, with branches nearly as long. Here, also, Spiranthes autumna- 

 lis occurs; i. e., in almost all pastures, excepting those depastured by 



sheep.

Oil the Contrast afforded by the internal Structure of the Stems of 

 Equisetum limosum and E.fluviatile. By J. G. Baker, Esq. 



Since sending my former observations upon the Equiseta, I have 

 been favoured with an illustrated report of a carefully conducted 

 microscopical investigation into the anatomical structure of these 

 plants, kindly undertaken, for the purpose of confirming or disproving 

 their distinctness as species, by R. Etheridge, Esq., Curator of the 

 Bristol Institution. 



I am sending herewith, for publication, the drawings supplied by 

 that gentlemen, so that the means of forming a decision respecting 

 this question will be equally open to all ; and further comment than 

 a brief abstract of his notes upon the leading points of contrast will 

 be rendered superfluous.
