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.

Book Description
Excerpt from The American Monthly Microscopical Journal, Vol. 15: Containing Contributions to Biology, for 1894 The first question is how to obtain the proper material for investigation. Here, a mistake is often made; the so-called yeast-cakes manufactured and advertised as -manufactured of pure yeast- are by no means pure; everybody who knows a little of pure cultures and mycological work can see this. The yeast-cakes are very often made of yeast, (but by no means pure), a fair amount of starch, and a fair amount of bacteria is also found. It might be added that there are teachers who let their students work with this material, and who tell them that the starch-grains visible in the field of the microscope serve as a food for the yeast cells which break up the grains and form carbon dioxide and alcohol. The only place for obtaining good materials for study is the brewery. A 200 c. c. bottle, sterilized, and wrapped in sterilized filter-paper, is taken to the cellar of the brewery where the fermentation takes place. It is unpacked and. by means of a sterilized string, lowered into one of the vessels. When it is nearly filled, it is drawn up under the surface of the fluid, and corked, before it is taken out in the air. It may be well to take two samples from the same vessel, one a few inches under the surface, and one. at the bottom of the vessel. Two clean sticks will facilitate the latter, one fastened to the bottle, and the other one to the cork. Experience teaches the manipulation. Two such samples should be taken at the beginning, and two at the end of the fermentation. The flasks should be carefully packed and taken to the laboratory. If the preliminary examinations cannot be made at once, the flasks may be kept in an ice box for a few days.

Book Description
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.

Book Description
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.
