Matthew was so fascinated with his anatomy class in high school that he decided to study kinesics in college.
Secondly, the histology of fossil plants, particularly woody plants of the carboniferous period, has been placed on a sound basis, assimilated with general histological doctrine, and has considerably enlarged our conceptions of plant anatomy as a whole, though again.
Filicales and Gymnosperms, and known as the Cycadofihices, a group in which, curiously enough, the reproductive organs remained undiscovered for some time after the anatomy of the vegetative organs was sufficiently well known to afford clear evidence of their true affinities.
Theoretically this branch of the subject should connect with and form the completion of morphological anatomy, but the field, has not yet been sufficiently explored to allow of the necessary synthesis.
No indications beyond those furnished by comparative anatomy help us to unravel the phylogeny of the Collembola.
Fuller knowledge has shown that Macgillivray was ill-advised in laying stress on the systematic value of adaptive characters, but his contributions to anatomy were valuable, and later investigators, in particular H.
The inspection of the liver for purposes of divination led to the study of the anatomy of the liver, and there are indeed good reasons for believing that hepatoscopy represents the startingpoint for the study of animal anatomy in general.

It held its meetings at first in the church of the monastery of the Cordeliers, - the name given in France to the Franciscan Observantists, - now the Dupuytren museum of anatomy in connexion with the school of medicine.
In 1720 Valentini published, at Frankfort-on-the-Main, his Amphitheatrum Zootomicum, in which again most of the existing accounts of the anatomy of birds were reprinted.
But these and many other contributions, 4 made until nearly the close of the 18th century, though highly meritorious, were unconnected as a whole, and it is plain that no conception of what it was in the power, of Comparative Anatomy to set forth had occurred to the most diligent dissectors.
About the same time, having shown too open sympathy with the revolutionary or reforming tendencies of 1848, he was for; olitical reasons obliged to leave Berlin and retire to the seclusion of Wiirzburg, the medical school of which profited enormously by his labours as professor of pathological anatomy, and secured a wide extension of its reputation.
Borelli (1608-1679) as its most notable name, entered in a way on the mechanical study of anatomy suggested by Descartes, but was probably much more dependent upon the positive researches of Galileo.
Martin described the visceral and osteological anatomy of one which had been received alive the preceding year.
Th internal anatomy of the Hydromedusae shows numerous variations.
The conception of evolution is being applied more rigidly to the comparative anatomy of organs and systems of organs.
These attempts, however, to perpetuate the usage were finally discredited by Huxley's important Lectures on Comparative Anatomy (1864), in which the term was finally abolished, and the "radiate mob" finally distributed among the Echinodermata, Polyzoa, Vermes (Platyhelminthes), Coelenterata and Protozoa.
The term Anatomy, originally employed in biological science to denote a description of the facts of structure revealed on cutting up an organism, whether with or without the aid of lenses for the purposes of magnification, is restricted in the present article, in accordance with a common modern use, to those facts of internal structure not concerned with the constitution of the individual cell, the structural unit of which the plant is composed.
In such cases the characters of the adult tissue clearly depend solely upon the characters of the cell-walls, and it is usual in plant-anatomy to speak of the wall with its enclosed cavity as the cell, and the contained protoplasm or other substances, if present, as cell-contents.
This was not only in itself an important contribution to plant anatomy, but served as the starting-point of a series of researches by Van Tieghem and his pupils, which has considerably advanced our knowledge of the details of histology, and also culminated in the foundation of the doctrine of the stele (Van Tieghem and Douliot, Sur la polystlie, Ann.
A very considerable body of knowledge relating to this subject already exists, but further work on experimental lines is urgently required to enable us to understand the actual economy of plants growing under different conditions of life and the true relation of the hereditary anatomical characters which form the subject matter of systematic anatomy to those which vary according to the conditions in which the individual plant is placed.
In this article (A) the general anatomy of birds is discussed, (B) fossil birds, (c) the geographical distribution.

In zoology, the mollusca are divided into cephalous and acephalous (Acephala), according as they have or have not an organized part of their anatomy as the seat of the brain and special senses.
In recent years classifications in part agreeing with the older schemes but largely original, in accord with researches on the comparative anatomy of the insects, have been put forward.
(the beautiful version of the story of the nightingale's death) is translated from Strada; while the scheme of the tedious interlude exhibiting the various forms of madness is avowedly taken, together with sundry comments, from Burton's Anatomy of Melancholy.

Comparative anatomy and embryology prove that this condition is due, not as formerly supposed to a difference in the relations of the visceral commissure which prevented it from being included in the torsion of the visceral hump, but to an actual detorsion which has taken place in evolution and is repeated to a great extent in individual development.

Belon, as has just been said, had a knowledge of the anatomy 1 This was reprinted at Cambridge in 1823 by Dr George Thackeray.
But, though apparently without such a knowledge of the anatomy of birds as would enable him to apply it to the formation of that natural system which he was fully aware had yet to be sought, he seems to have been an excellent judge of the characters afforded by the bill and limbs, and the use he made of them, coupled with the extraordinary reputation he acquired on other grounds, procured for his system the adhesion for many years of the majority of ornithologists.'
P. 187, note), the skeleton of a fowl to which was attached the head of a hornbill was for a long time exhibited in the Museum of Comparative Anatomy at Paris !
This very remarkable treatise forms the groundwork of almost all later or recent researches in the comparative anatomy and consequent arrangement of the Passeres, and, though it is certainly not free from inperfections, many of them, it must be said, arise from want of material, notwithstanding that its author had command of a much more abundant supply than was at the disposal of Nitzsch.
But in addition to bringing forward a fundamental and philosophical view of morbid processes, which probably contributed more than any other single cause to vindicate for pathology the place which he claimed for it among the biological sciences, Virchow made many important contributions to histology and morbid anatomy and to the study of particular diseases.
Cuvier's term in its wide extension, however, passed into general use; but, as the anatomy of the different forms became more fully known, the difficulty of including them under the common designation made itself increasingly obvious.
ANATOMY OF PLANTS
That chapter of comparative anatomy (together with other anatomical details, for which see the separate articles) is now dealt with in the article Skull; here only the most avine features are alluded to, and since some of Parker's original illustrations have been retained, the description has been shortened considerably.
