We felt some surprise, on examining the specimens from the 

 Circars, to find that, while they had the same most remarkable 

 form of stigma that characterises the genus, they differed essen- 

 tially in the number of parts. That both species, however, be- 

 long to the same genus, cannot for a moment be doubted ; and 

 we have accordingly given the above specific character to the 

 Ceylon plant, which, we regret to say, we are only acquainted 

 with from Jussieu'*s description. In the Circars plant, although 

 the filaments of the stamens be united with a triangular column, 

 yet each face, a little below the apex, bears two anthers, making 

 in all six. We, as well as Jussieu, are unacquainted with the 



fruit.

Ancient Geological Changes in England. By Dr Fitton. 



X HE country around Hastings, and that of some neighbouring 

 districts, is principally of secondary formation ; the deepest or 

 oldest rock visible is Portland-stone, above which, in succession, 

 there are Wealden beds (consisting of Purbeck beds, Hastings 

 sands, and Weald clay), lower greensand, gault, upper green- 

 sand, and chalk as the uppermost or newest rock of the series. 

 In Dr Fitton's delightful Geological Sketch of the Vicinity of 

 Hastings just published, we find the following as general results, 

 obtained from a consideration of the geognostical arrangements 

 around Hastings and the vicinity. 



" We have thus,"^ says Dr Fitton, " gone through the list 

 of the strata connected with the tract in the vicinity of Hastings, 

 from the chalk down to the Portland-stone; and the general 

 inferences from what has been mentioned are so obvious, that a 

 statement of them will be more like a repetition of the facts 

 themselves, than a train of laborious reasoning.
