Scaly-tree^ is derived from the imbricated appearance 

 of the surface of the stem, occasioned by the form and 

 arrangement of the little angular imprints or scars left by

 tree with age. The markings produced by the attachment 

 of the leaves are never obliterated. In their structure, ex-

 butions of specimens, and instructive observations on the chalk fossils 

 of Wiltshire, afforded me important assistance in my early attempts 

 to investigate the organic remains of Sussex.
