The microscope micrometer, which contains the micros cope as an essential part, is used extensively (2) In the measurement of the position of stars on the astro-photo graphic Chartsand plates obtained by the International Con gress for their catalogue of all stars of the first eleven mag nitudes; (3) In the determination of differential stellar parallax from photographic plates; (4) In the study and observation of the heavenly bodies as advances in astro nomical photography make it possible to produce slides of sufficient fineness for the purpose.

Excerpt from The American Monthly Microscopical Journal, Vol. 19 Aspergillus Repens. - This mould grows much like the Penicillium and Mucor shown in -The Microscope- for September last. The mycelium is like that of Penicillium. The spore head is quite different (h). Primarily the fertile branch of Aspergillus is single-celled, non-septate, while those of Penicillium are septate. The apex of the fertile branch is swollen, club-like, from which swollen end called columella (12 to 36 microns in diameter) the spores, k, are borne from single, flask-shaped bodies marked din the cut and called sterigmas. The spores are 6 to 8 microns, slightly roughened, at first yellowish, later greenish to gray. In later cultures small yellowish bodies are found scattered in the superficial mycelium. These are a second sort of fruit-bearing body and contain spores 4 to 6 microns in diameter. They are somewhat lens-shaped and have serrate margins, k. The yellow perithecium is shown at m. This mould grows scantily upon various media. Upon blood serum it does not grow at all. Milk is made alkaline by it, does not coagulate, becomes thick and stringy and shows the presence of albumoses. If a solution has developed in it a mould, it is not advisable to filter the solution and return it to stock for the active ingredients have probably undergone some changes. Throw it away.

Excerpt from The American Monthly Microscopical Journal, Vol. 18: Containing Contributions to Biology; For 1897 Owing to the high death rate of these Indians from tuberculosis, he became interested in their vital statistics and published a paper in the Boston Medical and Surgical Journal entitled "The Vital Statistics of an Apache Indian Community" in which their statistics for five years were compiled, and which is of interest as probably being the only accurate vital statistics of an Indian community ever published. From New Orleans, Dr. Borden was transferred to Fort Adams, Newport, Rhode Island, and from there to his present station, Fort Snelling, near St. Paul, Minnesota. Dr. Borden first began work in Microscopy when attending his first course of medical lectures. At that time a three years graded course of study and practical work in histology and patholog were required but in few of the medical colleges of the United States of which the Columbian University was one, and as he became interested in microscopical work, the graded course gave him more time to follow his studies in that line than was available to the average medical student. After entering the Medical Department of the Army he continued his microscopical work and soon began work in photomicrography. He is the author of a number of monographs on subjects connected with general and military medicine, histology, microscopical technique, photomicrography, and photography, and he is a member of the Associations of Military Surgeons of the United States, and a Fellow of the Royal Microscopical Society of England.

Excerpt from The American Monthly Microscopical Journal, Vol. 12: Containing Contributions to Biology, for 1891 Nor do the valves separate along the raphe or median line, but along the line of junction or suture. If the reader will turn over a page or two to the conspectus, he will see it stated by H. L. Smith, of Tribe I, Raphidieae, for example: "Frustules, mostly bacillar in s. v., always with a distinct raphe on one or both valves." (Italics mine.) Thus the two statements do not agree, and that on p. x will be likely to give the student a very different idea of what is meant by the raphe. But to return to our article. The trouble has all come, in my opinion, from calling the inner portion of the valve a hoop at all. For it suggests at once a barrel-hoop, something which is free at both edges from that which it encloses; which is not usually the case with the diatom hoop, to say the least. It is a misleading term, and is bound to confuse the student. It would be much better, therefore, it seems to me, to drop it altogether, or to speak of this piece as that portion of the membrane of each valve which when separated from the valve has the shape of a hoop. For as long as it is attached to the valve it is not a hoop, but the continuation of the valve itself. Finding this portion, however, at times detached, and shaped like a hoop, observers have thought there was only one hoop to each frustule, and that it bound the two valves together, whereas the truth is that there is a so-called hoop to each valve, and the hoops found in settlings of the Diatomaceae did not come each from a frustule but each from a valve, that is, two from each frustule. (There may be a few exceptions, but in my opinion the above will hold as a general statement.) Now, I am inclined to believe that very few amateurs have had the occular demonstration of this fact. Having to write upon the subject, and finding it impossible to reconcile the figures with what Carpenter said, I went to my slides again, and with the binocular, and almost the first peep at Isthmia showed me that the drawings were faulty in representing the upper and lower edges of the two valves as continuous lines instead of broken ones. And then I took down Schmidt's plates and the whole thing was as clear as day. And my advice to the student is to do the same thing: to pick out all his slides of Isthmia, Biddulphia, and Triceratium, and using the binocular, look sharp at the upper and lower edges of the hoop, and he will soon see that each is not one continuous line, but is formed by two lines, one of which is inside the other. And then if he is fortunate he will find some frustules where the valves have partly separated, and he will find that each valve has its band or hoop, and that it forms one continuous piece with the valve. And when he has done this he will have done something that is better than resolving Amphipleura, for he will have gained a definite idea of the structure of the diatom frustule. And this is a point that cannot be too strongly insisted upon, since even the Micrographic Dictionary has gone through edition after edition without stating or figuring the matter correctly. The first thing then for the student to do is to get a correct idea of the way the two valves are put together, and to do this he must not rely upon the figures in the Micrographic or in Carpenter, but study carefully the actual diatoms with the binocular.
