DR. J. W. DAWSON ON ERECT TREES CONTAINING ANIMAL 
2. Characters and Contents of the Erect Trees. 
It may be well in the first instance to present in a summary form the characteristics 
and contents of each tree extracted, taking’ them in order, from the shore cliff to the 
end of the reef, 1,063 feet in all, and including those extracted prior to 1878 with the 
others. The positions of the several trees may be seen on the plan and section. 
No. 1. Lyells tree of 1851, which comes first both in order of time and position. 
Diameter, about 17 inches; height, unknown; distance from crop of coal. 
No. 12, in bank, about 99 feet. Contained remains of Dendrerpeton Acadia¬ 
num , Hylonomus Wymani or Lyelli , and Pupa vetusta. 
No. 2. Extracted in 1860. Diameter, 1 foot 8 inches; height, 9 feet; distance from 
No. 1 about 73 feet; surface obscurely ribbed. Contained Dendrerpeton 
Acadianum and Pupa vetusta. 
No. 3. Extracted in 1879. Diameter, 1 foot 8 inches; height, 2 feet 6 inches; 
distance about 20 feet from No. 2. Filled with argillaceous matter, and a 
little mineral charcoal at base. No animal remains observed. 
No. 4. Extracted in 1879. A crushed coaly bark covering a mound of mineral 
charcoal. No animal remains observed. Distant about 20 feet from No. 3. 
No. 5. Extracted in 1877. Diameter, 2 feet 6 inches; height remaining, about 
4 feet. Surface with flat ribs. Distance from No. 4, 93 feet, and from the face 
of the cliff in 1879, 58 feet. This tree was extracted under unfavourable 
circumstances, owing to the interference of debris from the foot of the cliff, and 
high tides. It afforded portions of a skeleton of Dendrerpeton Acadianum, 
bones of Hylonomus Lyelli, Pupae, and fragments of Millipedes. On one 
surface was a trail running round the circumference, indicating the efforts of an 
imprisoned Batrachian to escape. A few much decayed bones on this surface 
appeared to belong to Dendrerpeton, 
No. 6. Extracted in 1879. Diameter, 2 feet; height remaining, less than a foot. 
This was probably the base of a tree, of which the upper part had been 
removed by the sea, leaving only the lowest layer. Afforded some much 
decayed bones, apparently of Hylerpeton. This tree was distant only a few 
feet from No. 5. 
No. 7. Extracted in 1879. Distant from No. 5, 66 feet. Merely the base remain¬ 
ing. Consists of mineral charcoal without fossils. 
No. 8. Extracted in 1879. Diameter, 1 foot 6 inches; remaining height, 1 foot. 
Consisted entirely of black carbonaceous matter with bones. It afforded 
several skeletons of Hylonomus and Dendrerpeton, the first observed remains 
of Hylerpeton, and many Pupae and Millipedes. The skeletons in this tree 
were less disturbed than in any other I have examined ; but owing to the long 
.exposure of the base of the tree, after removal of the upper part, the material
