This plate illustrates the exceptional opportunity afforded the palaeontologist through the remarkably preserved remains of Ichthyosaurs in the quarries of Holzmaden near Stuttgart, Wurttemberg, excavated for many years by Herr Bernard Hauff.
That wealth of evidence which the zoologist enjoys, including environment in all its aspects and anatomy in its perfection of organs and tissues, the palaeontologist finds partially or wholly destroyed, and his highest art is that of complete restoration of both the past forms and past environments of life (see Plates I.
This line of hypothesis and demonstration is typical of the palaeogeographic methods generally - namely, that vertebrate palaeontologists, impressed by the sudden appearance of extinct forms of continental life, demand land connexion or migration tracts from common centres of origin and dispersal, while the invertebrate palaeontologist alone is able to restore ancient coast-lines and determine the extent and width of these tracts.
In other words, the origin, or first appearance of new characters, which is the essence of evolution, is an orderly process so far as the vertebrate and invertebrate palaeontologist observes it.
The public buildings include the town hall, a fine and commodious house on the site of the old tolbooth; the Falconer museum, containing among other exhibits several valuable fossils, and named after Dr Hugh Falconer (1808-1865), the distinguished palaeontologist and botanist, a native of the town; the mechanics' institute; the agricultural and market hall; Leanchoil hospital and Anderson's Institution for poor boys.
Yet another family, according to the palaeontologist last named, is typified by the genus Stylacodon, of the English Purbeck.
The task of the palaeontologist thus begins with the appearance of life on the globe, and ends in close relation to the studies of the archaeologist and historian as well as of the zoologist and botanist.
KARL LUDWIG FRIDOLIN VON SANDBERGER (1826-1898), German palaeontologist and geologist, was born at Dillenburg, Nassau, on the 22nd of November 1826.
The evolution of the modern Echinoidea from their Palaeozoic ancestors is also well understood, but in this case the ancestral form to which the palaeontologist is led does not at first sight present many resemblances to the Pelmatozoa.
