This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1908 edition. Excerpt: ...branches are its most peculiar character. The mode of branching by which this apparently paired arrangement of the branches is produced, is too much obscured by the close budding to be observable. The branches are so little compressed that they appear as tubes, where all other graptolites are completely flattened out. This results from their having been provided with an exceptionally thick periderm. To the latter fact the straight and rigid appearance of the branches, so characteristic of the form, is also due.
