masses is about 45 feet in diameter, of irregular shape and lighter color, 

 than the detached masses, and evidently has not oeen nearly so much 

 subjected to the action of fire as the latter ; they are much softer, and 

 have interstices filled with earthy matter, which has been subjected to 

 great heat, but are only partially vitrified. 



This substance either passes into unburnt clay of the 1st alluvial 

 stratum, or the stratum of superior sandstone, on both of which it 

 rests, (Specs, c and d.) 



The singular appearance and conformation of the detached masses 

 could not fail to attach something of the marvellous to them. Native 

 tradition states them to be the stones which the army besieging Lunka, 

 under Rama and Lutchmun, were enjoined to bring for the purpose 

 of building the celebrated bridge ; but enough having been accumulated, 

 messengers were despatched with the news, two of whom posted 

 themselves at Murk a and Mhow, two ghauts on the Jumna, and each, 

 JLungoor and Talah, arriving with his load, hearing the welcome tid- 

 ings, it was deposited here, and he proceeded lightly on his journey. 

 I had this version from a Brahmin, who begged me, whilst getting my 

 specimens, to remember that such relics should on no account be 

 disturbed. 



Of Isolated Masses, the Remains of Beds of Nodule Kankar. 

 Whenever these remains occur, the river is by their considerable 

 extent generally contracted in its course, causing the water to rush 

 through the narrow but deep passages between isolated masses of 

 what was once one continuous bed. 



The passage at Karim Khan (fig. 1, PI. XVI.) (the point d'appine of 

 the Janina works,) is now and has been perhaps for centuries, solely 

 affected by the presence of the remains of an extensive bed of no- 

 dule kankar, and is at the present moment the worst pass in the river 

 for boats passing downwards at all seasons and upwards in the mon- 

 soons. As a description of this is applicable in its general outlines to 

 every locality where these remains occur, I shall confine myself to it. 

 This bed has originally been and is still partially connected with 

 and resting on the right bank of the river; its surface I imagine to be 

 about 75 or 80 feet below the average level of the Bundelkhand bank, 

 and the bed of the river to be about 16 feet below the surface. The left 

 or Diiab bank is not above two-thirds the height of the opposite one, 

 and is protected by a very extensive shingle shoal; had it been a bank 

 on which the stream would have made any impression, the river would 

 have certainly taken a course more free from impediments than the 

 one it now pursues. The stream being thus confined, has, by the 

 gradual deepening of the river throughout its course, been at last
