Page 639 - Chessy deposits, that is, in a quartzose rock scattered in nuggets varying from the size of a pea to that of a walnut. All the ores carry, besides iron and silica, a small percentage of manganese and alumina, together with an amount of zinc varying from two to eight per cent.
Page 118 - ... although some of them habitually, and all occasionally, act also in obedience to other stimuli. There are other muscles or muscular fibres which are entirely withdrawn from the control of the will, such as those of the heart and intestinal canal, and these are accordingly named
Page 15 - GUINEA-PIG. (Highly magnified.) a, a largo cell, the nucleus of which appears to be partly divided into three by constrictions ; 6, a cell the enlarged nucleus of which shows an appearance of being constricted into a number of smaller nuclei ; c, a so-called giant-cell or myeloplaxe with many nuclei ; d, a smaller myeloplaxe with three nuclei ; ei, proper cells of the marrow ; jt, various forms of coloured nucleated cells, some in process of division.
Page 88 - In all bones, the part next the surface consists of compact substance, which forms an outer shell or crust, whilst the spongy texture is contained within. In a long bone, the large round ends are made up of spongy tissue, with only a thin coating of compact substance ; in the hollow shaft, on the other hand, the spongy texture is scanty, and the sides are chiefly formed of compact bone, which increases in thickness from the extremities towards the middle, at which point the girth of the bone is least,...
Page 56 - ... tissues. It is, moreover, continuous throughout the body, and from one region it may be traced without interruption into any other, however distant ; a fact not without interest in practical medicine, seeing that...
Page 241 - ... thus named, which seem chiefly intended to contribute to the perfection of the skin as an organ of touch, seeing that they are highly developed where the sense of touch is exquisite, and vice versa.
Page 101 - The cancellous tissue is supplied in a similar way, but by less numerous and larger vessels, which, perforating the outer compact tissue, are distributed to the cavities of the spongy portion of the bone. In the long bones, numerous apertures may be seen at the ends near the articular surfaces; some of these give passage to the arteries...
Page 100 - CONTENTS. (Highly magnified.) a, small arterial capillary vessel ; 0, large venous capillary ; n, pale nerve-fibres cut across ; /, cleft-like lymphatic vessel : one of the cells forming its wall communicates by fine branches with the branches of a bone-corpuscle. The substance in which the vessels run is connective tissue with ramified cells ; its finely granular appearance is probably due to the cross-section of fine fibrils.
Page 138 - HIGHLY MAGNIFIED. The fibre looks in optical section like a tube — hence the term tubular, formerly applied to these fibres. Two partial breaches of continuity are seen in the medullary sheath, which at these places exhibits a tendency to split into laminae.
Page 131 - The nerves of a voluntary muscle are of considerable size. Their branches pass between the fasciculi, and repeatedly unite with each other in form of a plexus, which is for the most part confined to a small part of the length of the muscle or muscular division in which it lies. From one or more of such primary plexuses, nervous twigs proceed and...
