Excerpt from Description of the Plates of the Fauna Antiqua Sivalensis
[This description has been mainly compiled from the following sources: - 1. Memoranda in Dr. Falconers note-books and papers; 2.References to certain of the figures in his published memoirs on Elephant, Mastodon, c.; 3.References to other figures in his correspondence with scientific friends; and 4. Labels in his handwriting on the specimens figured which are now in the British Museum. Although the figures are drawn to scale, the actual measurements have, as far as practicable, been introduced into the description of each figure. It has been thought that by their means, the value of the descriptions would be increased to those who have not an opportunity of consulting the Plates, and that even to those who possess the Plates the comparison of specimens would be facilitated. The measurements are given in English inches, and in tenths of an inch. The letters B.M. indicate that the specimen referred to is in the British Museum.]
Plates I., II., and III. are intended to represent, by careful copies of nature, the modifications in structure and form exhibited by the molar teeth of the Proboscidea. They show in vertical sections a series of gradations, commencing with Dinothermm and Mastodon Ohioticus at one extremity, and running through the other species to Elephas primgemus, in which the greatest deviation from the ordinary form of a grinding tooth is met with. Plate I. Fig.1. Elephaspriviigenius, ox the true Mammoth: longitudinal and vertical section of last upper molar, left side, from an English specimen found near Kingsland, and formerly in the Museum of the Geological Society. Shows the ridge formula and the form and relative proportions of the alternate layers of ivory. The section closely resembles that of the corresponding tooth of the Indian Elephant, but the ivory segments are even thinner, more vertical, ancimore approximated.
