128 Geology of the South East of Dorsetshire. 



The proprietors of the estates of Zopten and Langenols, in Silesia, have 

 besides tried to naturalise this species last spring, by procuring eggs from 

 the south of France, by the diligence, well packed in a box, the interstices 

 being filled with the elastic husks of beans. This experiment has hitherto 

 been attended with better success than the former : the eggs were hatched 

 by hen turkeys, the young reared in the open air, and the preserve of those 

 estates is now stocked with eighty-five well-fledged young. — W. Weis sen-

[The red-legged partridge is in such bad repute with English sportsmen, 

 that we believe a very general wish is felt, in the counties overrun by this 

 bird, to effect its extermination, rather than to extend its range to other 

 parts of England. — Ed.]

 {Concluded from p. 88). 



I do not exactly comprehend Dr. Mitchell's meaning in the 

 second and third paragraphs of p. 590. I have sufficiently 

 explained that my sketch was intended to represent the order 

 of the formations in one line only, from south to north ; it 

 was impossible to describe in that line the chalk and chalk 

 marl from east to west, from Ballard Head to Punfield, be- 

 cause it is not seen in the line assumed ; therefore, the chalk 

 does begin, as I stated, at Ballard Head : and literally so, for 

 Ballard Head is a promontory, and the allusion of Dr. M. is 

 to the side of this promontory, and not to its transverse sec- 

 tion, which was all I considered. But as Dr. M. alludes to 

 this side of the promontory, I must explain the appearances 

 he mentions, so as to clear up his mystery. " We soon began," 

 he says, "to see lines of flint towards the top of the cliff; 

 which, in some places, dip about 40° to the east. Towards 

 Ballard Point, they become quite horizontal, there being still 

 chalk without flint at the bottom." The explanation of this 

 is very easy. The lofty ridge of chalk, of which Ballard 

 Point is a section, slopes down on the southern side, in some 

 places gradually, in others by stages of descent, to the shore, 

 along which are strewed heaps of fallen masses from above, 

 partially obscuring the gault and lower green sand, which rise 

 close to the shore, and in one or two places form an under- 

 cliff, from 10 to 12 feet high. The lines of flint at the top, 

 are, therefore, nothing more than the continuous summits of 

 the vertical layers, which thus appear horizontal or inclining 

 to the east, according to the various characters of the diffe- 

 rent portions of the slope. "The chalk without flints at the 

 bottom," is the chalk marl, which, with its characteristic fos- 

 sils, rises in its proper place, between the chalk and the gault, 

 to the south of the former ; but, owing to the slope and the 

 debris, appears to be below the chalk with flints, when it is
