similarity between them and the Sigillaria of a former world. It is 

 certainly remarkable that numerous layers of bark are deposited one 

 on the other, far more so than in all other trees, and one consequence 

 of this is that they compress each other into a flattened shape, and 

 that the outer bark falls off. The cells, however, of the new layers are 

 flatter than in general. The ligneous bundles pass from the wood 

 to the scars of the leaves ; and such a diff'erence in the form of these 

 scars on the outer bark and beneath it, as that observed by Ad. Bron- 

 gniart in the Sigillarice, was not perceptible. The wood is very thin, 

 even in the thickest stems of succulent plants ; the bark and pith 

 very thick ; they remain a long while succulent and then rot, so that 

 their preservation among fossil bodies is very improbable. — From the
