The Human Paroccipital Fissure viagra online source Should it be Recognized and so Designated ? Dr. Wilder also read a paper on this subject. Ten years ago the same writer suggested that the occipital portion of the long fissure, called intraparietal by Turner, interparietal by Ecker, and parietal by Pansch, be regarded as a distinct fissure under the title paroccipital, referring to its constant and marked relation to the dorsal end of the occipital (parieto-occipital). The " D" shaped area between the two or first annectent gyrus lie pro- posed to call the paroccipital gyrus. I he grounds viagra online source for this suggestion have been given in the ' Reference Handbook of the Medical Sciences," viii., 155, as follows : (1) In about half the cases examined by the writer there are two fissures separated by an isthmus of greater or less width; (2) when the two are contin- uous there is always a vadum (shallow) at viagra online source the point corresponding to the isthmus; (3) each of the two portions, whether separate viagra online source or continuous, is usually deepest at or near its middle; (4) at their first ap- pearance in the fcetus they are always completely in- dependent. While this division is recognized by some observers, it is thought needless In others, and viagra australia delivery has not as yet received the sanction of the German Committee on Anatomical Nomenclature. The present paper was intended to review all the accessible literature on the subject, as well as the ma- terial accumulated by Dr. Wilder in the interval, es- pecially comparing these parts with similar fissures found in apes and monkeys. On practical grounds the writer believes that the fissure should be recognized, and called the paroc- cipital division of a " fissural complex.'' Among eight educated persons the complete isthmus occurred seven times, in all but one on the right side. In only one case did the isthmus occur on the left side and not on the right, and that was the case of an insane Swiss patient. Practical Histology for Large Classes. Dr. Charles S. Minot, of Boston, presented a communi- cation, in which he said that in Boston they had entirely given up allowing students to make their own prepa- rations, and had found the change to be an advanta- geous one. Every student is obliged to make a per- fect draw ing of each preparation, viagra online source and the drawing is judged on its accuracy. The geometrical faculty is especially developed. In the second half-year they are given practical work, and they then begin the study of the embryo.- In commencing the work they are given specimens of the liver, heart, spleen, etc., instead of beginning with a connective tissue, a viagra online source piece of bone, or the like. It had been found advan- tageous to teach embryology as a help to anatomy, and as offering an viagra online source explanation to a viagra online source great many relations that would otherwise be obscure. Some Novel Methods of Description of the Human Skull Dr. Harrison Allen, of Philadelphia, in a paper on this subject, said that his method is to se- cure viagra online source a formula for each skull. He begins with the supraorbital ridge, and draws a line between this point and the outer part of the external auditory process. The nasal bone may be divided into three parts, viagra australia delivery the upper part, the frontal ; the main portion, the maxil- lary, and the third part, the pre-maxillary. In the human skull the third portion is not well defined. The frontal portion is very variable. Holding the bone in such a position as to examine it in profile it is possible to tell the proximal from the distal por- tion. The latter it is well to call the radix, and be- low that the salient. Variations in these portions serve to identify the individual. In two skulls of Sandwich Islanders which Dr. Allen presented, the one had a viagra online source well-developed incisor crest and the other had not. . . . The anterior nasal spine is simply the end of the incisor crest. It has received the name of infantile, but Dr. Allen prefers the word pidomorphic. The writer believed that the hard palate lias not received the attention which it deserves in its poste- rior part. In negroes the middle lacerated foramen is very much narrowed and is frequently closed. The temporal fossa may be divided into two parts, the fronto-temporal ridge and the parietal temporal. They are distinctly different. The former is very apt to be closed, and is very rarely continuous with the same line as the parietal temporal. No two skulls show a similar arrangement. In a study of the tem- poral bone the remains of a suture are sometimes found between the squamous and petrous portion. For the lower portion of this suture the name retro-tympanic has viagra online source been proposed. In speaking of the lacrymal bones Dr. Allen said that scarcely any portion of the 9 8 MEDICAL RECORD. [January 18, 1896 lacrymal bone is in advance of the crest. In the North American Indian viagra online source and in the Sandwich Islander they are apt viagra australia delivery to be very small. Observations on the Fossa Capitis and a Tubercle in the Trochanteric Fossa Dr. F. J. Brockway, of New York City, presented a carefully prepared paper on this subject. The fossa capitis, which in the hu- man femur is found at the extremity of that bone and gives attachment to the ligamentum teres, presents or-
