This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1880 edition. Excerpt: ...are round cells, the protoplasm of which is highly tinged with haematoxiline, and which are provided with a bulky central nucleus each, as is shown in Fig. 26. The nuclei are approximately spherical and very coarsely granular, the granulations being dyed almost black by haeniatoxiline. Judging from the analogy with other animals, the parts just described must be interpreted as follows: The whole of each spermatocyst arises from a single cell, in which the original single nucleus gives rise by division to the secondary nuclei, each of which becomes a spermatoblast, the original cell enlarging until it becomes a cyst; the mother nucleus also divides into nuclei like itself, which become transformed into the peculiar nuclei before mentioned, in the wall of the cyst. This is of course all hypothetical, not based upon direct observation, for in all the seminiferous tubes I have had an opportunity of examining the cysts and spermatoblasts were all fully formed. The most complete and satisfactory account which I am acquainted with of the development of the spermatozoon is that given of the frog by La Vallette.283 I would also refer those who wish to understand the great theoretical importance of these facts to the brief summary of the observations previously made, which I have published elsewhere.28 "is Vallette: Arcbiv fdrilikros. Anat., Bd. xii, 8. 797, Taf. xxiv, xxxr (1876). Minot: Theory of Impregnation. Prec. Boston S. N. H., 1377; vol. xix, p. 165. Let us now return to the examination of au isolated tube. In it also we can recognize the single cysts, and we perceive at once that each cyst pursues its independent development, and gradually changes into one of the bundles that appear so very plainly in the second segment, Fig. 25II. It will...
