top to the bottom, — these all serve as guides to the restoration 

 of the original form of the aerolite, so far as these two parts of 

 it are concerned, and are the grounds of justification for the 

 restoration of this part of the meteorite which I have attempted, 

 by moulding the small intermediate piece, to unite the two 

 stones, and which is marked on the figure with the number 4. 

 The Qutahar stone, which becomes thus adapted to the Piprassi 

 piece, is a fine mass of an irregular wedge shape (it is num- 

 bered 5). The inner side is fitted with large shallow depres- 

 sions, and presents a rather concave surface. The outer side is 

 flat and smooth. The base on which it stands, and which is the 

 result of the wedge-like form, is also smooth, rounded at the 

 edges, and presenting hollows and irregularities on one half of 

 its surface, while to the side of this base, on the inner or just 

 below the concave part of the stone, the irregular piece that fell 

 at Chireya adapts itself. This last fragment (numbered 6) is 

 somewhat pitted and deeply grooved on its upper side, and 

 rounded everywhere else. Indeed, notwithstanding the pre- 

 cision with which it fits to the Qutahar stone, the faces and 

 edges at the parts of contact are rounded off so as almost to 

 obliterate the original form of the stones at this part. The 

 contour presented by the reconstructed mass, so far as the 

 reuniting of these scattered fragments enables one to build it 

 up, is that of a shell or the thick outer rind of one side of a 

 considerable aerolite. 



The lithological character of the Piprassi, Qutahar, and Chi- 

 reya stones is very similar to that of the Bulloah pieces. But 

 there are differences between them worthy of being noticed. 

 Thus the crust on them is not very different from the dense black 

 crust that coats those of Bulloah ; it is, however, less charac- 

 teristic and less thick. They are all dull, as the crusts on highly 

 olivinous meteorites generally are, as contrasted with the shining- 

 enamels on the felspathic-augitic kinds. It exhibits crystalline 

 metallic-looking points, as well of iron as of meteoric pyrites 

 and, at very rare intervals, of iron pyrites, that are disseminated 

 among small globular projections of a pitch-black colour. It is 

 these black projections, on the other hand, that constitute the 

 whole mass of the Bulloah crust. But in the three larger 

 masses the crust assumes a dirty blackish-brown hue. 



The facts above recorded appear to me to throw some light 

 upon several interesting questions. 



We may hazard a pretty safe conjecture as to the direction 

 of the Butsura fall, by observing that the lighter stones fell to 

 the S.E. of the heavier ones ; the Bulloah three miles S.E. of 

 Piprassi ; the Chireya a similar distance E.S.E. of Qutahar. If 

 we suppose that the disruption of all the stones was simul-
