Schulenburg, Francis J. Sullivan, A.B., A.M., John F. Ross, George B. Trible, RULES FOR THE GUIDANCE OF Definite times are set for holding the examinations of each half-year's work (see Calendar). If for any reason a student wishes an examination at any other than the regular times, he may have it with the consent of his instructor and on the payment of a fee of five dollars to the Registrar. Examinations in all lecture courses will be conducted in writing, and the value of the returned papers will be indicated by the letters, A, B, C, D and E, which expressed in percentages The grade C is the lowest which a student may receive and yet pass an examination. The grade D implies that the student is conditioned and must take the examination over again; while the grade E signifies an absolute failure, and the student receiving this mark must repeat the course in which he has failed before he can have another examination. A student conditioned a second time in a given subject must take the subject again in class before he will be re-examined in it. Two years is the maximum time allowed for the accomplishment of one year's work. A student failing to comply with this regulation shall be compelled to withdraw from the school. No credit will be given to a student for a year's work until he has satisfactorily completed all work for preceding years. A student who is allowed to take advance work shall receive no credit for that work until he has completed the studies of the year to which such course or courses belong. A student who fails of promotion shall be required to pursue and pass examinations in all work of the class to which he belongs. Such students, moreover, shall pay full tuition for four consecutive years spent in this school and none thereafter. Students must pay laboratory fees for every laboratory course taken. Students are responsible for their behavior, and the Faculty reserves the right to terminate the connection of any student with this institution if, for any cause, he shall prove himself unfit to pursue his professional studies. All the property of the school, apparatus, specimens, books, etc., is for the use of the students in the prosecution of their studies. Every encouragement is offered for the fullest employment of this equipment. All that is necessary to get the freest access to this property is that the student make an application in due form to the teacher, or other person in charge, so that a receipt can be taken and a proper record of the whereabouts of such articles be kept. For microscopes, etc., a deposit must be made for security. It is forbidden to remove property of the school without obtaining due permission. THE SPIROCHETE PALLIDA AND ITS DEMONSTRATION IN SECTIONS. By DR. E. F. TIEDEMANN, Professor of Pathology and Bacteriology. Early in 1905 Schaudinn and Hoffmann published their discovery of a micro-organism almost constantly present in the primary and secondary lesions of syphilis. It is a very delicate spiral organism, to whch they gave the name spirochete pallida, on account of the pale stain which it takes when stained with certain aniline dyes. The discovery was quickly confirmed by a great many observers; only a few dissenting voices were heard, who claimed that the spirochetes were accidental contaminations derived from the staining fluids, that they were elastic fibrils, etc. A few observers also claimed that they found the spirochete pallida in non-syphilitic secretions and lesions. But this has not been corroborated, and today it is an accepted fact that the spirochete pallida is an organism found in syphilis, and in no other disease. In ulcerating external syphilitic lesions there is often found another spirillum, which is larger and darker, and has longer and flatter curves, to which the name spirochete refringens has been given. This was described as long ago as 1837, by Donné. It is readily distinguished from the spirochete pallida by staining more easily and deeply, and by its greater size and open curves. It is not peculiar to syphilis, having been found in other ulcerating lesions. Care must be taken not to mistake the spirilla occurring in the mouth for the spirochete pallida. The feeble staining properties of the latter serve as a distinguishing mark. Spirilla, which stain quickly and deeply with a watery solution of methylene blue, are certainly not the spirochete pallida. |
