The second, (Fig. 2,) which is applicable to greater spans, is nearly the same . The 
chains are less tightened, and the platform is supported by alight framing. 
In the 3rd form, (Fig. 3,) fulcra or piers are erected, over which the chains are 
suspended. The platform is then attached to them by vertically suspended rods ; 
the path or roadway passing between the supports. This form is applicable to the 
largest spans. 
When the breadth of the stream is considerable, and the depth not very great, 
economy and safety will be best consulted by multiplying the number of cuives, and 
having one or more supports in the bed of the stream : vibratory motion must 
naturally be expected where the length of chain is considerable and the platform 
narrow; but this may he obviated by applying horizontal chain guys in the 
manner represented in figure 1.

II. On some Petrified Shells found in the Gaivilgerh Range of Hills, 
in April 1823. By the late H. W. Voysey, Esq. Assistant Surgeon 
His Majesty’s 67th Foot. 
[From the Asiatic Researches, vol. xvit- pt. i.] 
This remarkable range of hills is called, by Arrowsmith, in his last map, the 
Bindih, orBindaehull (Vindhya orVindliyachala) bills. The same name is, however, 
given to a lofty range of hills on the left bank of the Goddveri, as it passes through 
GondwSna, and also to those near Gualior. I shall, therefore, distinguish them by 
the name of the Gdwilgerh range, particularly as, after repeated enquiries, I have 
never been able to discover that they were as above designated, either by the inhabi- 
tants of those hills or of the neighboring plains. They take their rise at the conflu- 
ence of the Purna and Tapti rivers, and running nearly E. and by N. terminate at a 
short distance beyond the sources of the Tapti and Wardor. To the south- 
ward, they are bounded by the valley of perar ; and to the north, by the course of 
the Tapti. The length of the range is about one hundred and sixty English miles, 
and average breadth, from twenty to twenty-five miles. 
On the Southward side they rise abruptly from the extensive plain of Berar, 
the average height of which is one thousand feet above the level of the sea, and 
tower above it to the height of two and three thousand feet. The descent to the 
bed of the Tapti is equally rapid, although the Northern is less elevated than the 
Southern side of the range. The outline of the land is generally fiat, but much 
broken by ravines, and by groupes of flattened summits, and isolated conoidal 
frustra. 'The summits and the flat land are generally remarkably destitute of 
trees, but thickly covered by long grass: — in the ravines and passes of themountains 
the forest is very thick, and, in many places, almost impervious. The inhabitants 
are principally Goands, whose language, manners, and customs differ remark- 
ably from those of the Hindus. At present, their chief occupation is hunting, and
