surrounded by a cicatrix of a dull colour, which is frequently orbicular, but sometimes 
polygonal. If we cut them open we observe a small cavity, surrounded by a ring of 
shining black brittle coal (tigs. 19 b, 20, 21 & 22). Fig. 22 is a magnified transverse 
section of the middle; tig. 20 (magnified 20 5) a similar section, but nearer the top of 
the fi-uit, which is not compressed; and tig. 19 (magnified 19 5, 21) a section of a com- 
pressed fruit. The wall of the fruit measures 1 to 1^ millim. ; the cavity has a diameter 
of about 2 millims. The black shining crust which covers the internal surface is very 
thin. It is formed by the testa, if the organization belong to a fruit ; but if it be the 
seed of a Taxus, or of some tree resembling the latter, then it ought to be considered as 
the remains of the albumen, while the wall forms the ligneous testa. The cavity is 
always filled with a whitish-grey clay. As in the CayyoUthes Wehsteri, the softer internal 
parts of the seed were also in this case dissolved, while the cavity became afterwards filled 
with mineral substance. The crust of coal corresponds to the cuticula of C. Wehsteri.

A remarkable little object, which represents, without doubt, the stone of a fruit. It 
is 3-^ millims. long and 3 1 % millims. wide, being thus nearly orbicular, although it is 
furnished with a rather blunt apex, which projects but very little, while the lower 
end is rounded very obtusely. At one place we observe a narrow fissure, which reaches 
from the apex to somewhat below the middle of the little stone, which is bordered by a 
narrow margin. It is, without doubt, the place where the raphe passed, and it may 
therefore be described as the umbilical fissure. The furrows and ribs upon the little 
stone are very elegant. On the truncated end (fig. 26, highly magnified) we observe a 
great many parallel furrows and ribs, which run very near one another to the lower 
termination of the umbilicus, and which pass also opposite the umbilicus across the 
back of the little stone ; the sides too are marked by similar ribs and furrows ; but here 
the first two are distant, and the furrows are therefore wider ; the ribs run much more 
irregularly, forming ramifications, so that the furrows seem to be interrupted by 
numerous tubercles. The furrows and the ribs are covered besides with innumerable 
dots. (In fig. 24 5, a piece with a few ribs has been represented as seen under a 
microscope.) 
Similar fruit-stones occur in Celtis, but we miss the umbilical fissure and the regularity 
of the furrows. As regards the character, the stone is more like those of Frunus, 
in which we observe on the suture a channel, within which the raphe runs till it passes 
through a hole below the apex of the stone towards the seeds. On the fossil we find no 
such small hole resembling a dot, but only the above-mentioned fissure ; besides it differs 
in the very peculiar sculpture, and must therefore belong to another type of plants. 
Fig. 27 represents the little stone of the natural size; fig. 24, the same magnified and 
viewed laterally ; fig. 25, the same from the side of the umbilicus ; fig. 26, from the base.
