It has been argued that the elaborate structural adaptations of the nervous system which are the corporeal correlatives of Theory complicated instincts must have been slowly built up by the transmission to offspring of acquired ex perience, that is to say, of acquired brain structure.

Selling his Baltimore works, he built, in 1836, in partnership with his brother Thomas, a rolling mill in New York; in 1845 he removed it to Trenton, New Jersey, where iron structural beams were first made in 1854 and the Bessemer process first tried in America in 1856; and at Philippsburg, New Jersey, he built the largest blast furnace in the country at that time.

It is seen that aldoses and ketoses which differ stereochemically in only the two final carbon atoms must yield the same osazone; and since d-mannose, d-glucose, and d-fructose do form the same osazone (d-glucosazone) differences either structural or stereochemical must be placed in the two final carbon atoms.3 It may here be noticed that in the sugars there are asymmetric carbon atoms, and consequently optical isomers are to be expected.

Many derivatives are known, some of which exist in two structural forms, exhibiting geometrical isomerism after the mode of fumaric and maleic acids.

The last structural peculiarity of the group is the absence of the functions of regulation and reparation which are so highly developed in the more primitive Planarians.

On the other hand, he advances too easily from the maxim that function is prior to, and makes, structure to the conclusion that the results of use and disuse are therefore immediately incarnated in structural adaptations capable of hereditary transmission.

The Carpathians do not form an uninterrupted chain of mountains, but consist of several orographically and geologically distinctive groups; in fact they present as great a structural variety as the Alps; but as regards magnificence of scenery they cannot compare with the Alps.

Ashmead's " super-families " have, however, been adopted as - founded on definite structural characters - they probably indicate relationship more nearly than the older divisions founded mostly on habit.

They are usually regarded as forming a single family - the Apidae - but there is very great diversity in structural details, and Ashmead divides them into fourteen families.

The student will find differences among anthropologists in the interpretation of these marks - some averring that comparative anatomy is worthless as a means of subdividing the American subspecies, others that biological variations point to different Old World origins, a third class believing these structural variations to be of the soil.

In size and several structural features it approximates to the more typical Cervicaprinae, as represented by the reedbuck (Cervicapra), and the waterbucks and kobs (Cobus or Kobus), all of which are likewise African.

The principal manufactures are coke, chemicals and boots and shoes; among others are iron and structural steel.

In arranging plants according to a natural method, we require to have a thorough knowledge of structural and morphological botany, and hence we find that the advances made in these departments have materially aided the efforts of systematic botanists.

All Hydrozoa, in the first place, exhibit the three structural features distinctive of the Coelentera.

The internal structural differences are even more characteristic. In the hydropolyp the blastopore of the embryo forms the adult mouth situated at the extremity of the hypostome, and the ectoderm and FIG.

In 1873 he published an important contribution to science, a map and paper in which he proved that the existing maps of Asia entirely misrepresented the physical formation of the country, the main structural lines being in fact from south-west to north-east, not from north to south, or from east to west as had been previously supposed.

Jefferson, Jessamine, Warren, Grayson and Caldwell counties have valuable quarries of an excellent light-coloured Oolitic limestone, resembling the Bedford limestone of Indiana, and best known under the name of the finest variety, the " Bowling Green stone " of Warren county; and sandstones good for structural purposes are found in both coal regions, and especially in Rowan county.

The chameleons (q.v.) have many structural peculiarities.

It is with respect to this number of segments that respectively constitute the pygidium and the midregion of the body that Trilobites differ most markedly from each other; and it is a singular fact that the extremes in structural organization in this particular to be met with in the Trilobita are found side by side in strata of Cambrian age.

Such was the structure of the appendages in Trilobites belonging to the genus Triarthrus; but considering the great structural differences that obtain between Triarthrus and many other genera, it would be rash to assume that there were not corresponding differences in the structure of the limbs.

The complexity of the glacial period and its subdivision into several glacial epochs, separated by interglacial epochs of considerable length (certainly longer than the postglacial epoch) has a structural consequence in the superposition of successive till sheets, alternating with non-glacial deposits, and also a physiographic consequence in the very different amount of normal postglacial erosion suffered by the different parts of the glacial deposits.

In 1866 the Russian embryologist Kowalewsky startled the zoological world with a minute account of the developmental changes of Ascidia, one of the Tunicata, 5 and it became evident that the affinities of that class were with the Vertebrata, whilst their structural agreements with Mollusca were only superficial.

The structural features which the Mollusca do possess in common with other animals belonging to other great phyla of the animal kingdom are those characteristic of the Coelomata, one of the two great grades (the other and lower being that of the Coelentera) into which the higher animals; or Metazoa as distinguished from the Protozoa, are divided.

Indeed, despite the fact that they present much diversity of habit - some being arboreal, as the squirrels, many of which are provided with expansions of skin or parachutes on which they glide from tree to tree; some cursorial, as the hares; others jumpers, as the jerboas; others fossorial, as the mole-rats; and others aquatic, as the beavers and waterrats - no important structural modifications are correlated with such diversity of habit.

On account of certain structural peculiarities, the rats of Madagascar, which have a dentition like that of the cricetine Muridae, are separated as a distinct family, Nesomyidae.

If he is to be believed, at the bottom of all organic evolution organic impulses becoming habits produce structural changes, which are transmitted by heredity; and as an impulse thus gradually becomes secondarily automatic, the will passes to higher activities, which in their turn become secondarily automatic, and so on.

The most marked advances from 1900 to 1905 were in worsted goods (61.4%) structural iron-work (60%), and tin and terne-plate (54.4%) Philadelphia is the great manufacturing centre.

Other important manufactures in 1905 were petroleum products ($2,006,484); lumber and planing mill products ($1,604,274); women's clothing ($1,477,648); children's carriages and sleds ($ 1, 4 6 5,599); car-shop construction and repairs, by steam railway companies ($1,366,506); carriages and wagons ($ 1, 22 5,387); structural iron work ($1,102,035); agricultural implements, bicycles, automobiles (a recent and growing industry), plate and cut-glass (made largely from a fine quality of sand found near the city), tobacco, spices and malted liquors.
