Book excerpt: Excerpt from The American Monthly Microscopical Journal, 1897, Vol. 18: Containing Contributions to Biology While the idea of the arrangement in the experiment below detailed is suggested from a study of the Abbe form of apertometer, it is essentially different in half the technique. For the benefit of those who are not familiar with the instrument and in the hope that I may make the proposed modification plainer, it may not be amiss to attempt a short explanation of its working, particularly as this is not done in the Zeiss catalogue. It consists essentially of (a) an auxiliary objective and (b) the plate glass semicircular and prismatic disc.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

The cork should be lifted cautiously, and a glass rod dipped down to the bottom of the bottle. When it has been taken out again rapidly, the drop hanging at its end is placed on a slide a cover is put over it, and we have now a sample ready for microscopic examination. Before entering upon the various organisms which might come under observation, it ought to be remem bered that drawings of everything seen should be put down in the note book.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Monthly Microscopical Journal, Vol. 10: Containing Contributions to Biology Cover each tumbler with paper to keep out dust but to let in air. Put them away, a set of three in a moist dark place, a set of three in a moist light place. In the pure water, whether in the dark or the light place, two or three days will have produced no change. In the syrup or the cake, from both places, spots of green will have appeared upon the surface. Therefore, mould grows in the dark as well as in the light, and will not grow in water containing no organic matter. In similar ways it may be shown that mould grows well on meat broth and other watery media; that it grows faster in warm places and slower in cold places. 2. Examination with Low Power. - Upon the tip of a needle catch the smallest possible speck of mould, add a drop of water, cover it and place under the low power. There will perhaps appear some very fine threads, but mainly a great dimness with some very dark curved lines. This mount is a failure, proving that water is not a universal mounting medium. That might have been suspected from the water not moistening the film when first tried. Begin again with the needle, and now use alcohol upon the slide. When viewed under the microscope it will appear that the mould is made up of fibres matted together. These will show still better under the high powers. Before using them, mount a new slide in alcohol, carefully teasing the speck of mould before covering it. To tease it, take a needle in each hand, hold down the speck with one needle and pull the mould away with the other one. This separates the fibres for easier inspection. As the alcohol evaporates rapidly meanwhile, some more must be added from time to time, getting it under the cover with a pipette. 3. Under High Power. - The teased speck now appears to be a great complex of fine wavy threads. They make up the large part of the mould, and are called Hyphae (webs) because of their being matted and woven together. These are of two kinds: - (1.) which run indefinitely, many having no cross partitions; (2) which are broken by transverse joints and which terminate in branches tipped with small spheres. Besides these two kinds of hyphae numerous small spheres called conidia will be found in the mount. The hyphae Sand conidia together constitute the mould. The next question is, how are they put together. If a mould growing on a fluid-like broth be carefully examined one can see that it consists of a coat or scum which floats on the fluid, and that from this, called the mycelium hyphae carrying the dust before noticed are borne aloft into the air. These are invisible to the naked eye, but careful examination of bits caught with the needle from such a film convinces you that there are two kinds of hyphae, those of the mycelium and others arising from them into the air. 4. The Mycelial Hyphae. - A single thread from the complex, under medium power, is illustrated in figure i of the plate. Observe the long and narrow, flexuous, and parallel-sided thread or hyphae; that it branches frequently; that these branches are of equal diameter with the main stem; that the stem is not empty but contains something, and that the stem is one continuous tube through all its length and not broken by subdividing cross-walls. The older mycelial hyphae are not one single tube, but, like the aerial hyphae, are transversely divided.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Monthly Microscopical Journal, Vol. 11: Containing Contributions to Biology for 1890 The slide cases sold by dealers being often expensive, many persons will prefer the one shown in the frontispiece, Figures 1 and 2. Make a pine box, of which the inside measurements are 71/2 by 8, and 3 in. deep. If deeper, the box becomes too large to grasp comfortably in the hand. The lid should hinge on one of the 71/2 in. sides, and the opposite side of the box should let down flat by means of a pair of hinges at the bottom. Cut a number of squares of cardboard for trays, 71/4 by 73/4 .Then for each tray cut two half-inch strips of stoutest pasteboard, 73/4 in. long; three strips of the same width, 61/4 in. long. With glue or thick gum affix the two long and two of the short strips to the cardboard close to the edge, and use the remaining short piece to divide the central space equally into two. The size of the spaces will be 61/2 by 31/8, and each tray will hold a dozen slides. My own box, 3 in. deep, holds 24 of these trays, capable of accommodating 288 slides, and the cost of the whole is a little over one dollar, or less than one-fifth for the same amount of accommodation in boxes sold for the purpose. The cardboard and pasteboard must be cut with a knife, not with scissors; if gum is used it must be well dissolved, strained, and very thick, and each tray as it is made must be placed under a weight, one on the top of another. If the thickness of the pasteboard is not enough to furnish depth for the slides containing objects mounted in raised cells, it can be increased by adding a thickness of cardboard, or even another of pasteboard. An Inexpensive Reagent Block. A frequently expressed need of some convenient and inexpensive block or case in which to place the reagents and apparatus used in the biological laboratories, leads me to describe the form I have used for some time. (Frontispiece, figure 3.) It is a plain whitewood block, 15 c.m. square and 4 c.m. thick. On the upper side of this three grooves are cut, each 15 c.m. deep. The first is 1 c.m. from the edge and 1 c.m. wide. The second is 1 c. m. from it and 3.5 c.m. wide. The third is 1 c.m. from it and 2 c.m. wide. Into one end there is glued a closely-fitted block 1 c. m. long, and in the other end one 5 c.m. long, leaving a trough for slides about 90 c.m. long. In the place where these last blocks is glued is bored a hole 1.5 c.m. in diameter and 1 c. m. deep, into which tightly fits a paper pill box for covers. The remainder of the block is provided with two rows of 5 holes, each 2 c.m. in diameter and 3.5 c.m. deep, for reagent phials. The first groove is used for razor, and the second for pencils, pipette, forceps, etc. The block is easily made; costs very little; is very neat in appearance, and convenient in work.
