Recent years, of Zeiller in France, and Scott, Seward and others in England, has advanced our knowledge of the anatomy of ~fossil plants in an important degree.
History and Bibliography.The study of plant anatomy was begun in the middle of the seventeenth century as a direct result of the construction of microscopes, with which a clear view of the structure of plant tissues could be obtained.
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.

No indications beyond those furnished by comparative anatomy help us to unravel the phylogeny of the Collembola.
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.
Th internal anatomy of the Hydromedusae shows numerous variations.
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.
From Mohl down to the eighth decade of the century the study of anatomy was entirely in the hands of a group of German.
Trans., Systematic Anatomy of Dicotyledons, Oxford, 1908), brings together so many of the facts as are at present known in an orderly arrangement.
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.
Anatomy Of Birds I.
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.

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.
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.
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.
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.
Long before, and by many writers on the anatomy of Yarnell birds.
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.
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.
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.
ANATOMY OF PLANTS
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.
