Page 108 - Theory, which, when maturely developed, promises to .offer a solution of this difficult and complex Problem. " If it be admitted that fissures may have been produced by changes in the temperature of the earth, there can be little difficulty in also admitting that electricity may have powerfully influenced the existing arrangement of the contents of mineral veins. How are we otherwise to account for the relative positions of veins of different kinds with respect to each other, and likewise of their...
Page 26 - CBE Near its upper margin is a wedge-shaped elevation (b) and near the inferior margin, a notch or furrow (a). These salient and reentering portions articulated with corresponding depressions and projections on the surface of the adjacent vertebra, and acted as pivots, admitting a limited amount of lateral vibrations, and at the same time preventing any slip, or dislocation. Fig. 6. Concave surface of Fig. 5. ; the wedge-shaped projection near its lower margin (a) must have articulated with a corresponding...
Page 106 - Combe, so common in the names of upland Villages, is usually applied to that unwatered portion of a valley, which forms its continuation beyond, and above the most elevated spring that issues into it; at this point, or spring head, the valley ends, and the Combe begins.
Page 22 - Robert Gutch, of Segrave. (Original.) In Fig. 1 ; a, b, c, d, are portions of ribs, and e, f, g, h, are fragments of sterno-costal bones (nat. size). The spaces between these bones, are covered with the remains of skin ; the Epidermis being represented by a delicate film, and the Rete mucosum by fine threads of white Carbonate of Lime ; beneath these the Corium, or true skin, is preserved in the state of dark Carbonate of Lime, charged with black volatile matter, of a bituminous and oily consistence....
Page 14 - ... extinct genus Psammodus. t Fig. 27. In most, if not all the species of Platycrinites the arms are subdivided ; they are not so in this figure, as from its small size they could not well be represented. The figure is intended to give only a general idea of the subject. 39. Scolopendrium. r. Taeniopteris in Oolite. Scarborough, f. LAND ANIMALS. 40. Didelphys. r.

Page 84 - Briareus, (nat. size) on a slab of Lias from Lyme Regis, covered with a large group of the same animals, in the collection of the Geological Society of London. (Original.) Fig. 2. Rare and beautiful specimen of Briarean Pentacrinite, from the Lias at Lyme Regis, in the collection of Mr. Johnson, of Bristol, shewing the plated integument of the abdominal cavity, terminated upwards by a flexible Proboscis, and surrounded by the commencement of the arms and fingers. This part of the animal is very seldom...
Page 110 - It should be observed that in proportion as the deposition of the metals proceeded, the voltaic action must necessarily have been considerably augmented, so as to render it highly probable that the metals were chiefly deposited at rather an early period in the history of the containing veins ; and their intersection by other veins seems to strengthen this probability." Mr. Fox has found by experiment that when a solution of muriate of Tin is placed in the voltaic current, a portion of the metal is...
Page 85 - Mr. JV Thompson has more recently conjectured that the Pentacrinus Europaeus, which in early life is fixed by its stem to other bodies, is produced from the ovum of the Comatula, and becomes afterwards detached, and forms a perfect Comatula, capable of moving freely in the Ocean ; at one time crawling amongst sub-marine Plants, at others floating, or swimming like Medusae. (See Proceedings of Royal Society, London, June, 1835.) Fig. 3. Small Briarean Pentacrinite, adhering to a fragment of Jet from...
Page 86 - Fig 4» the joints are of three degrees of magnitude ; those at a. being the largest, those at c. the smallest and thinnest, and those at b. of an intermediate size. The edges of c. appear at the surface only upon the salient portion of the column, Fig. 4. (See VI p. 436, Note.) Figs. 6, 7, 8, 9, 12, 13.
