Excerpt from The Microscope and Histology, Vol. 1: For the Use of Laboratory Students in the Anatomical Department of Cornell University; The Microscope and Microscopical Methods Illustrated This, the third edition of "Notes on Microscopical Methods for the Use of Students in the Anatomical Department of Cornell University." has been entirely rewritten, enlarged, and more fully illustrated; and while elementary matters have received fuller treatment than in previous editions, in this, an especial effort has been made to give a more adequate account of Homogeneous Immersion Objectives, the Sub-Stage Illuminator. Camera Lucidos, the Micro-Spectroscope and Micro-Polariscope, that is to apparatus which is coming to be used more and more in the higher fields of investigation in pure science and in practical medicine. It is thoroughly believed by the writer that simply reading a work on the microscope, and looking a few times into on instrument completely adjusted by another, is of very little value in giving real knowledge. In order that the knowledge shall be made alive, it must be made a part of the student's experience by actual experiments carried out by the student himself. Consequently exercises illustrating the principles of the microscope and the methods of its employment have been made an integral part of the work. In considering the real greatness of the microscope, and the truly splendid service it has rendered, the fact has not been lost sight of that the microscope is, after all, only an aid to the eye of the observer, only a means of getting a larger image on the retina than would be possible without it; but the appreciation of this retinal image, whether it is made with or without the aid of a microscope, must always depend upon the character and training of the seeing and appreciating brain behind the eye. The microscope simply aids the eye in furnishing raw material, so to speak, for the brain to work upon. The necessity for doing a vast deal of drudgery or "dead work," as it has been happily styled by Prof. Leslie, before one has the training necessary for the appreciation and the production of original results, has been well stated by Beale: "The number of original observers emanating from our schools will vary as practical work is favored or discouraged. It is certain that they who are most fully conversant with elementary details and most clever at demonstration, will be most successful in the consideration of the higher and more abstruse problems, and will feel a real love for their work which no mere superficial inquirer will experience. It is only by being thoroughly grounded in first principles, and well practised in mechanical operations, that any one can hope to achieve real success in the higher branches of scientific enquiry, or to detect the fallacy of certain so-called experiments." In preparing this manual it has been taken for granted that the student is already familiar with elementary physics, especially the subject of optics. The experiments in micro-chemistry (Ch. V.) are given for the sake of practice for the junior chemical students who take the course in order to gain a knowledge of the microscope as an aid to chemistry. In part II will be given the application of the microscope to study and investigation in Vertebrate Histology.

Excerpt from Histological Notes for the Use of Medical Students In taking the class of Practical Histology at the Owens College Medical School during the Summer Sessions of 1882-1883, it has been my custom to give each student "sheets" containing a short account of the chief points to be observed in the specimens for examination. This plan has been found of great assistance, but the descriptions being of necessity extremely short, it seemed preferable to increase their length, and to obtain this result the following notes have been printed. These notes are by no means intended as a full description of the histological structure of the tissues, neither are they given for the instruction of the student in the various methods of section-cutting, injection, etc.; but simply to aid him in his examination of specimens. The specimens were given to the student ready for mounting, since time would not allow him to stain and clear each section for himself; but it is desirable that this course should be followed now and again. The various staining, clearing, and mounting reagents are those in general use, but a brief account of those hardening processes, etc., which gave very good specimens, has been included.

Consolations of Philosophy Penguin
Alain de Botton, best-selling author of How Proust can Change Your Life, has set six of the finest minds in the history of philosophy to work on the problems of everyday life. Here then are Socrates, Epicurus, Seneca, Montaigne, Schopenhauer and Nietzsche on some of the things that bother us all; lack of money, the pain of love, inadequacy, anxiety, the fear of failure and the pressure to conform.
