THE comet which is fading in the morning sky is one of the most interesting that has ever appeared. Few, if any, have ever been more brilliant, and though others have been larger, and have continued visible for a longer time, none of them have presented more remarkable phenomena.

THE questions relating to public relief, population, and natural selection are so inseparable that, in our age, thought has been logically conducted from one to another of them, and has been led to important discoveries. It was the problem of public relief, and the observation of the effects produced by the poor-rates, that inspired Malthas to compose Ins “ Law of Population ” ; it was the law of population, in turn, that led Darwin to the discovery, first, of the law of the “ struggle for existence,” and afterward of that of “ natural selection.”

BY the cautious archæologist all evidences of ancient man in Eastern North America—exclusive of true palaeolithic implements— are wisely referred to those Indian tribes that, to within a comparatively recent period, were the sole occupants of the territory named.

I HOPE the time is not distant when a careful study of the living model of the child and the adult, and the whole period of the development of the one into the other, will form a part of the student’s ordinary course of anatomy and physiology, as such knowledge is essential to the surgeon engaged in removing and preventing deformities of the body.

TIE distribution of the Greenwich signals from the General PostOffice in London is effected by means of the Chronopher or Time-carrier, shown in perspective in Fig. 6, and in front elevation in Fig. 7.1 To this instrument the hourly signal from the observatory is sent by means of a special under-ground wire.

ON the 7th of June, 1882, a farmer, while cutting a drain through a meadow on his farm at Freehold, New Jersey, observing the appearance of bones, stopped the workmen, and sent for me to inspect the place. This I did the next morning. Approaching the spot, I * “Ou a Mastodon Americanus (Cuvier), found in a Beaver-Meadow at Freehold, New Jersey, by Samuel Lockwood.”

SOME of the higher animals have a peculiar faculty for accustomLing themselves to various kinds of poison ; and man, especially, often owes his ruin to that unfortunate talent, for the instinct of taste can be so perverted that the vilest and originally most repulsive substances become the most seductive.

MR.

IT was lately remarked in these columns that one of the dangers attendant on education was that it might lessen men’s powers of observation. There is no doubt, we apprehend, that this possibility does exist. Bookishness and absence of mind are no new faults among students.

PROFESSOR W. K. BROOKS
WE will now examine our various sources of information, in order to see how far the evidence which they furnish can be used to establish phylogenies. Comparative anatomy might not at first sight be expected to yield much of this kind of evidence, for the only animals which we can study thoroughly are those recent ones which have diverged very widely from their remote ancestors; and, while it is true that the study of the structure of living animals does not furnish direct evidence, the doctrine of homology supplies a means of sifting out, by general comparisons, what has been recently acquired from what is more deep seated, and of thus arranging animals in a series of groups of greater and greater extent and less and less contact.

OF the many characteristic features of the arid region of the far West known as the Great Basin, none attract the attention of the traveler more forcibly than the desert mud-plains that have been left by the evaporation of former lakes.

THE primary and leading object of the experiments with animals, which have been conducted at Rothamsted during the past thirty-five years, was the solution of practical agricultural problems ; but, as in the case of the field experiments already noticed, the practical lines of inquiry have naturally led to the investigation of a wide range of topics belonging to the science of biology, which, in themselves, are of more particular interest to the physiologist, or even to the student of sanitary or of social science, than to the farmer.

The other was fed on a mixture consisting of bean-meal, lentil-meal, and bran, each one part, and barley-meal three parts, given ad libitum, but accurately weighed, for a period of ten weeks, when it had nearly doubled its weight.

TAKING the case of a daguerreotype plate which has been exposed, and which we are about to develop by the action of mercury, I should like you to understand exactly what takes place in the plate when it is exposed and developed. On the surface of the plate we have a mixture of silver iodide and bromide ; but, for simplicity’s sake, I will suppose that it is simply silver iodide.

No greater calamity could have befallen American science than the recent and sudden death of Professor Henry Draper. The news of it was an inexpressible shock to his friends, and was felt with painful regret by the whole community. But forty-five years of age, with the full promise of apparent health, and in the midst of an active and a brilliant career, he was cut off by an illness so short that but few had heard of it when his death was announced.

ALTHOUGH the visit of Mr. Spencer to this country has been in some respects painfully unsatisfactory, yet in other and the most important respects it has been most gratifying and successful, His state of health was such that he was good for nothing for social purposes.

THE influence of John Stuart Mill upon the reputation of his father, James Mill, has been twofold : he has advertised him, and at the same time eclipsed him. It is frequently said of James Mill that his greatest work was John Mill ; and there arc many who suppose that this is his chief title to be remembered.

Mortality in Town and Country.—Professor Finkelnburg attempted to show, in a paper read at the recent Sanitary Congress in Cologne, that cities arc not of necessity less healthy than country districts, and that, where they appear to be so, the fact can generally be attributed to local influences affecting the hygienic or economical condition of the population.

DR. D. E. SALMON has pursued parallel investigations with those of M. Pasteur, of the microbe of hen cholera, and has conclusively satisfied himself of the accuracy of the results announced by the latter. He regards his researches as demonstrating that the virulent liquids of the fowl's body contain micrococci, that these can be cultivated, and that liquids in which bacteria are cultivated produce the disease by inoculation.
