 ... shaky foundations, and uneven tables, sometimes with the plates not half amalgamated, or coated with impurities, the whole concern superintended by a man who knows as little about the treatment of auriferous quartz by the amalgamating or any other processes as a dingo does of the differential calculus.

... in unweaving the maze, has its source in a misconception of the original machinery by which Christianity moved, and of the initial principle which constituted its differential power. In books, at least, I have observed one capital blunder upon the relations which Christianity bears to Paganism: and out of that one mistake, grows a liability to others, upon the possible relations of Christianity to the total drama of this world. ...

... We have actually succeeded in wringing from the tenacious and inflexible Cabinet of St Petersburg an important commercial advantage! On Lord Aberdeen's accession to office, he found Russia in the act of aiming a fatal blow at a very important branch of our shipping trade, by levying a differential duty on all British vessels conveying to Russian ports any goods which were not the produce of the British dominions. After, however, a skilful and very arduous negotiation, our foreign secretary has succeeded in averting that blow—and we retain the ...

Here he was addressing an audience containing a considerable number of dark men. Mr. Holton, his colleague, had orated about differential duties, very dry and Yankee- like, as usual. McGee followed in one of his arousing speeches. When he sat down, the respected negro landlord of "Uncle Tom's Cabin" got up to move a vote of confidence. And, according ...

As was to be expected, any proposal for the abolition of extra-territorial rights and the revision of the regulations in regard to import duties met with a strenuous opposition from the foreign residents in Japan. On the other hand, ...

One purpose of the double-wound electromagnet is to produce the so-called differential action between the two windings, i.e., making one of the windings develop magnetization in the opposite direction from that of the other, so that the two will neutralize each other, or at least exert different and opposite influences. The principle of the ...

To these we find nothing analogous in the other kingdoms, though the poorer classes of Welsh freemen had wergilds varying from 120 to 60 shillings. It should be added that the differential treatment of the various classes was by no means confined to the case of wergilds. We find it also in the compensations to which they were entitled for various injuries, in the fines to which they were liable, ...

We shall take it for granted that British and Irish products and manufactures enjoy a preference on import into the colonies, over imports from foreign countries, of at least five per cent, resulting from differential duties in favour of the parent state: it may be more, and we believe it will be found more; but such is the preference. This profit must be all to the account of the British exporter; for it is not received by the colonial custom-house, and whatever the reduction of prices by ...

But when a mere emotion assumed the importance and the reality of a solid body, she was seized by the indignant astonishment with which a mathematician might regard the differential calculus if it ceased suddenly to behave as he expected it to do. She had always controlled her own feeling with severity, and it was beyond the power of her imagination to conceive a possible excuse—unless ...

Others, however, assume that the psychical characteristics by which the sexes are differentiated result solely from individual differences in education.

Kerschensteiner has studied the development of this gift, and considers that his ...

In other words, the laws that govern unorganized matter are expressible, in principle, by differential equations in which time (in the sense in which the mathematician takes this word) would play the role of independent variable.
