In the Hirudo (fig. 178) a series of vesicles lined with mucous membrane, and richly supplied with blood vessels, are regarded as respirating sacs. § 383. Fishes respire by branchiae, or gills, for the support and-protection of which a complicated framework of bones, cartilages, ligaments, and muscles is provided; the form and arrangement of this apparatus varies in the different families and genera. It may, however, be classified into--1st. The lingual bone and branchiostegous rays; 2nd. The branchial arches; 3rd. The opercula or gill covers. The gills are for the most part attached to the branchial arches, which extend from the sides of the os hyiodes, backwards to the cranium. They are, in general, four in number on each side of the head, and are composed of numerous lamellae, placed closely together, and arranged in a regular series over the whole external convex margin of the branchial arches, like the barbs of a feather, or the teeth of a comb. Everything is arranged to afford the greatest possible extent of surface for the contact of the water with the mucous membrane on which a rich vascular network is spread. In the common ray, the extent of surface of the mucous membrane of the gills is estimated at 2250 square inches. In osseous fishes, as the pike and perch, the gills adhere by their superior border, and are covered by moveable opercula. In the cartilaginous genera, as the rays and sharks, they are attached by both borders, and there are no opercula; the water, which in the former enters by the mouth and escapes by the opercula, in the latter is expelled by a series of fissures situated at the sides...

Excerpt from An Introduction to the Study of Natural History: In a Series of Lectures Delivered in the Hall of the College of Physicians and Surgeons, New-YorkBefore he had passed the age of thirty-four, Agassiz had been made a member of every scientific academy in Europe. Many universities invited him to become one among their Professors; and the cities of Edinburgh and Dublin, in both of which he received the degree of LL.D. Enrolled him in the number of their citizens. His personal influence induced several persons of distinction to engage in the study of Natural History; among others, Sir Philip Egerton and Lord Enniskillen, whose collections are known to all paleontologists.The reputation and influence of M. Agassiz have rendered the little town of Neufchatel a nursery of Science, resorted to from all parts of Europe; and on his recommendation a young pupil of his, Dr.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
