THOSE inventions are deserving of special honor, and generally receive the most substantial recognition, which develop new industries or utilize waste products. The glycerine industry, which has attained colossal proportions, is a notable illustration of a great manufacture based entirely upon the saving of what until lately was a waste product of the soap-boiler.
PROFESSOR J. S. NEWBERRY. THE geological survey of the country bordering the fortieth parallel of latitude was made under the direction of the War Department by a party under Mr. Clarence King, who took the field in 1867. The area covered by the survey was a belt one hundred miles wide, traversed by the Pacific Railroad between the Great Plains on the east and the Sierra Nevada on the west, approximately between the 104th and 120th meridians of longitude.
IF the interest of a scientific expositor ought to be measured by the importance of the subject, I shall be applauded for my choice. In fact, there are few questions which touch more closely the very existence of man than that of animated motors—those docile helps whose power or speed he uses at his pleasure, which enjoy to some extent his intimacy, and accompany him in his labors and his pleasures.
HAVING no more documents until 1830, I propose to make a short critical review of Mill’s writings and doings in the interval, upon the basis of the information supplied by himself. I will first endeavor, for the sake of clearness, to extract the chronological sequence of the years from 1820 to 1830, which, from his plan of writing, is not very easy to get hold of.
IT has long been considered, as by common consent a law of health, that all food should be eaten slowly, not swallowed until well masticated. Some observations and experiments, however, have been recently made which indicate strongly that this principle of slow eating, so far as health is concerned, is not true with respect to all varieties of food.
THE CONDITION OF WOMEN FROM A ZOÖLOGICAL POINT OF VIEW.
W. K. BROOKS
TURNING now to another part of our subject, and bearing in mind the fact that by far the greater part of the external relations to which our actions are adjusted, and to which it is necessary that they should conform, in order to secure our preservation, safety, and welfare, are fixed and definite, and have been substantially unchanged for almost, if not quite, the whole period of human development, we see at once that, if the female mind is especially rich in the past experiences of the race, so far as these have resulted in laws of conduct, it follows that, since these experiences have been the same for all members of the race, there must be a greater uniformity in female character than in male character.
THE Geyser district of New Zealand is, at some future day, to be the great sanatorium of the southern world; meanwhile, it is so little known that some account of a visit lately made to it may not be uninteresting. While “ globe-trotting ” with a friend, we found ourselves in April last year at Auckland, New Zealand, and were kindly invited by the Governor to join him in a visit he was going to make, with the Commodore and a large party, to the geysers.
A MURKY London winter afternoon is not exactly a good opportunity for the pursuit of natural history. The snow lies thick on the pavement outside, half melted into muddy slush ; while the fog penetrates through the cracks in the woodwork, and the sun struggles feebly athwart the thick yellow sheet which shuts off his rays from the lifeless earth.
SIR HENRY THOMPSON. I THINK I shall not be far wrong if I say that there are few subjects more important to the well-being of man than the selection and preparation of his food. Our forefathers in their wisdom have provided, by ample and generously endowed organizations, for the dissemination of moral precepts in relation to human conduct, and for the constant supply of sustenance to meet the cravings of religious emotions common to all sorts and conditions of men.
THE name of the remarkable man whose likeness we give in this number of the “Monthly” is now intimately and imperishably associated with the establishment of the most important scientific truth that has been developed during the last hundred years—the “Conservation of Energy.”
THERE seems to be nothing so capable of throwing a “ scientist ” into a paroxysm of rage as the serious attempt to talk to him of spirit, spirit-world, “ spiritual body,” etc. In the words of Brewster, “spirit is the last thing he will give in to ” ; or, to put it in Huxley’s mild way, “ supposing the phenomena to be genuine, they do not interest me.”
THERE is a certain class of minds whose efforts to explain things generally leave them more obscure than they were before. In undertaking to represent a question they complicate rather than simplify it, and instead of helping the learner to understand a subject they hinder him.
THE EVOLUTION OF MAN : A POPULAR EXPOSITION OF THE PRINCIPAL POINTS OF HUMAN ONTOGENY AND PHYLOGENY. From the German of ERNST HAECKEL, Professor in the University of Jena, author of the “History of Creation,” etc. In two volumes, with 330 Illustrations.
Well-Water and Typhoid Fever.—In the summer of 1878 some forty persons in Rochester, whose supply of drinking-water was derived from a certain well, were taken sick with typhoid fever and other zymotic diseases. The health officer had the well closed, so that the people had to get water from other sources.
THE forty-ninth meeting of the British Association for the Advancement of Science will be held at Sheffield on Wednesday, August 20, 1879, under the presidency of Professor G. J. Allman, M. D., LL. D., F. R. S., L. & E. M. R. G. A., Pres. L. S. General Secretaries, Douglas Galton, P. S. Salator ; Assistant Secretary, J. E. H. Gordon.
