~Titrometric Assays.~--Within the limits of the error of experiment, a definite volume of a solution or gas represents a certain weight of metal or other substance, hence the exact weight may be determined by experiment. The error of experiment may be reduced to insignificant dimensions by repeating the experiment, and taking the mean of three or four determinations. This will at the same time show the amount of variation. Thus, if 0.5 gram of iron were dissolved and found to require 50.3 cubic centimetres of the solution of permanganate of potash, and if on repeating, 50.4, 50.2, and 50.3 c.c. were required, the experimenter would be justified in saying that 50.3 c.c. of the permanganate solution represent 0.5 gram of iron, and that his results were good within 0.2 c.c. of the permanganate solution. So that if in an unknown solution of iron, 50.5 c.c. of the permanganate solution were used up, he could state with confidence that it contained a little more than 0.5 gram of iron. With a larger experience the confidence would increase, and with practice the experimental error will diminish.

On receipt of this reply, sixty mounted soldiers, armed and provisioned, were sent over to the Cibicu to put a stop to the dancing. Apache scouts had been stationed to watch the manoeuvres of the Indians and to keep the officials informed. They met the troopers, who made a night ride to the stream, and informed them where the old medicine-man was encamped. Early in the morning the soldiers reached the Cibicu at a point about two miles above Nabakelti's camp, whence a detachment was despatched to arrest the medicine-man and bring him to the place where headquarters were being established. It was the intention merely to arrest and hold him while the troops rested for the day, preparatory to taking him back to the fort; but it was deemed necessary to send a force sufficiently large to cope with the Indians should they attempt resistance.

Three well-known writers, Professor Max Muller, Professor Mivart, and Mr. Alfred Russel Wallace have lately maintained that though the theory of descent with modification accounts for the development of all vegetable life, and of all animals lower than man, yet that man cannot--not at least in respect of the whole of his nature--be held to have descended from any animal lower than himself, inasmuch as none lower than man possesses even the germs of language. Reason, it is contended--more especially by Professor Max Muller in his "Science of Thought," to which I propose confining our attention this evening--is so inseparably connected with language, that the two are in point of fact identical; hence it is argued that, as the lower animals have no germs of language, they can have no germs of reason, and the inference is drawn that man cannot be conceived as having derived his own reasoning powers and command of language through descent from beings in which no germ of either can be found. The relations therefore between thought and language, interesting in themselves, acquire additional importance from the fact of their having become the battle-ground between those who say that the theory of descent breaks down with man, and those who maintain that we are descended from some ape-like ancestor long since extinct.
