FORE:A survey of the Socratic philosophy would be incomplete without some comment on an element in the life of Socrates, which at first sight seems to lie altogether outside philosophy. There is no fact in his history more certain than that he believed himself to be constantly accompanied by a Daemonium, a divine voice often restraining him, even in trifling matters, but never prompting to positive action. That it was neither conscience in our sense of the word, nor a supposed familiar spirit, is now generally admitted. Even those who believe in the supernatural origin and authority of our moral feelings do not credit them with a power of divining the accidentally good or evil consequences which may attend on our most trivial and indifferent actions; while, on the other hand, those feelings have a positive no less than a negative161 function, which is exhibited whenever the performance of good deeds becomes a duty. That the Daemonium was not a personal attendant is proved by the invariable use of an indefinite neuter adjective to designate it. How the phenomenon itself should be explained is a question for professional pathologists. We have here to account for the interpretation put upon it by Socrates, and this, in our judgment, follows quite naturally from his characteristic mode of thought. That the gods should signify their pleasure by visible signs and public oracles was an experience familiar to every Greek. Socrates, conceiving God as a mind diffused through the whole universe, would look for traces of the Divine presence in his own mind, and would readily interpret any inward suggestion, not otherwise to be accounted for, as a manifestation of this all-pervading power. Why it should invariably appear under the form of a restraint is less obvious. The only explanation seems to be that, as a matter of fact, such mysterious feelings, whether the product of unconscious experience or not, do habitually operate as deterrents rather than as incentives.Assuming, for example, that a machine will cost as much as the wages of an attendant for one year, which is not far from an average estimate for iron working machine tools, and that interest, wear, and repairs amount to ten per cent. on this sum, then the attendance would cost ten times as much as the machine; in other words, the wages paid to a workman to attend a machine is, on an average, ten times as much as the other expenses attending its operation, power excepted. This assumed, it follows that in machine tools any improvement directed to labour saving is worth ten times as much as an equal improvement directed to the economy of first cost.

FORE:The sudden and varied resistance to line shafts tends to loosen couplings, destroy gearing, and produce sudden strains that are unknown in other cases; and shafting arranged with the usual proportions for transmitting power will soon fail if applied to driving trip-hammers. Rigid connections or metal attachments ace impracticable, and a slipping belt arranged so as to have the tension varied at will is the usual and almost the only successful means of transmitting power to hammers. The motion of trip-hammers is a curious problem; a head and die weighing, together with the irons for attaching them, one hundred pounds, will, with a helve eight feet long, strike from two to three hundred blows a minute. This speed exceeds anything that could be attained by a direct reciprocal motion given to the hammer-head by a crank, and far exceeds any rate of speed that would be assumed from theoretical inference. The hammer-helve being of wood, is elastic, and acts like a vibrating spring, its vibrations keeping in unison with the speed of the tripping points. The whole machine, in fact, must be constructed upon a principle of elasticity throughout, and in this regard stands as an exception to almost every other known machine. The framing for supporting the trunnions, which one without experience would suppose should be very rigid and solid, is found to answer best when composed of timber, and still better when this timber is laid up in a manner that allows the structure to spring and [107] yield. Starting at the dies, and following back through the details of a trip-hammer to the driving power, the apprentice may note how many parts contribute to this principle of elasticity: First��the wooden helve, both in front of and behind the trunnion; next��the trunnion bar, which is usually a flat section mounted on pivot points; third��the elasticity of the framing called the 'husk,' and finally the frictional belt. This will convey an idea of the elasticity required in connecting the hammer-head with the driving power, a matter to be borne in mind, as it will be again referred to.

FORE:The coast was clear apparently, and the two culprits crept out. They reached the house at length and tried the door. It was fast! The Countess shook her hands passionately.

FORE:It seems as if we were witnessing a revival of Mediaevalism277 under another form; as if, after neo-Gothic architecture, pre-Raphaelitism, and ritualism, we were threatened with a return to the scholastic philosophy which the great scientific reformers of the seventeenth century were supposed to have irrevocably destroyed. And, however chimerical may seem the hopes of such a restoration, we are bound to admit that they do actually exist. One of the most cultivated champions of Ultramontanism in this country, Prof. St. George Mivart, not long ago informed us, at the close of his work on Contemporary Evolution, that, ��if metaphysics are possible, there is not, and never was or will be, more than one philosophy which, properly understood, unites all truths and eliminates all errors��the Philosophy of the Philosopher��Aristotle.�� It may be mentioned also, as a symptom of the same movement, that Leo XIII. has recently directed the works of St. Thomas Aquinas to be reprinted for use in Catholic colleges; having, according to the newspapers, laid aside 300,000 lire for that purpose��a large sum, considering his present necessities; but not too much for the republication of eighteen folio volumes. Now, it is well known that the philosophy of Aquinas is simply the philosophy of Aristotle, with such omissions and modifications as were necessary in order to piece it on to Christian theology. Hence, in giving his sanction to the teaching of the Angelic Doctor, Leo XIII. indirectly gives it to the source from which so much of that teaching is derived.

FORE:This state of improvement which has been reached in machine-tool manufacture, is not only the result of the skill expended on such tools, but because as a notable exception they are the agents of their own production; that is, machine tools produce machine tools, and a maker should certainly become skilled in the construction of implements which he employs continually in his own business. This peculiarity of machine-tool manufactures is often overlooked by engineers, and unfair comparisons made between machines of this class and those directed to wood conversion and other manufacturing processes, which machinists, as a rule, do not understand.These different plans will be considered first in reference to the effect produced upon the movement of carriages; this includes friction, endurance of wear, rigidity of tools, convenience of operating and the cost of construction. The cutting point in both turning and boring on a slide lathe is at the side of a piece, or nearly level with the lathe centres, and any movement of a carriage horizontally across the lathe affects the motion of the tool [124] and the shape of the piece acted upon, directly to the extent of such deviation, so that parallel turning and boring depend mainly upon avoiding any cross movement or side play of a carriage. This, in both theory and practice, constitutes the greatest difference between flat top and track shears; the first is arranged especially to resist deviation in a vertical plane, which is of secondary importance, except in boring with a bar; the second is arranged to resist horizontal deviation, which in nine-tenths of the work done on lathes becomes an exact measure of the inaccuracy of the work performed.
