from each other. The body being cut transversely, its whole surface 
appears like a net made up of pentagonal meshes, with a pentagonal 
star in each mesh. The sides of the columns are not exactly equal, 
and consequently not those of either the meshes or star.”* Speaking 
of a plate cut off the above specimen, the Doctor remarks that it 
takes as good a polish as any agate, and is a wonderfully beautiful 
stone. In another specimen he remarks that the ends of the columns 
terminate in several stellar cavities, at the under surface of the flint, 
much like those in the larger astroites, or starred honeycomb stone : the 
hollows being filled on the other side with a flinty matter. 
At Plate VI. Fig. 9, is represented a portion of a curious stone 
which I obtained from Gadsbridge, near Ingleborough. It is exter- 
nally of a dark grey colour, and is chiefly composed, as the Figure 
shews, of coralloid bodies of a very peculiar form, somewhat approach- 
ing to the fusiform figure which though externally dark are internally 
composed of a light coloured spathose matter, and are imbedded in a 
fine lime-stone which is nearly as dark internally, as it is on the 
surface. 
Examination of these bodies shews that they are externally deeply 
striated longitudinally. The striae commence at one extremity of 
the body, and proceed to the centre, bifurcating as the body en- 
larges. These same striae are then continued from the centre, and 
unite together as the body contracts in its dimensions. These longi- 
tudinal striae are decussated by transverse ridges, which are only dis- 
coverable in certain points of view. As far as can be judged from the 
situation of such of these bodies as are least concealed by the matrix 
in which they are imbedded, there seems to be reason for supposing 
that they are connected together at their most central and enlarged
