Excerpt from book: krnchen bilden sich acht zuerst lange und wenig dichte Stbchen oder Fden, die sich dann zu kurzen dicken Stbchen verkrzen und durch die inzwischen aufgetretenen Pol- krperchen oder Centrosomen derart gerichtet werden, dass vier von ihnen dem einen, die vier andern dem andern Pole zugewandt sind. Es erfolgt nun eine Theilung des Kerns und der Zelle, deren Resultat also zwei Tochterzellen sind, von welchen jede wieder ebenso viele Stbchen enthlt als die Ursamenzellen, nmlich vier. Daran schliesst sich unmittelbar, und ohne dass der Kern vorher ein Ruhestadium durchluft, nach demselben Schema eine zweite Theilung, durch welche die Zahl der Stbchen abermals halbirt wird, Fig. I., B Samenbildung von Ascaris megalocephala var. bivalens, frei nach O. Her t wig. A Ursamenzelle, B Muttersamenzelle, C erste Re- ductionstheilung, D die beiden Tochterzellen, E zweite Reductions- theilung, F die vier Enkelzellen-Samenzellen. so dass schliesslich jede Tochterzelle zweiter Ordnung deren nur eins enthlt. In Bezug auf die Kernstbchen besteht also der ganze Vorgang darin, dass zuerst die ursprngliche Zahl der Stbchen von vier auf acht verdoppelt wird, um dann durch zwei aufeinander folgende Theilungen zunchst halbirt, dann geviertelt zu werden. Das Endresultat ist somit eine Hal- birnng der in den Ursamenzellen enthaltenen Stbchenzahl. Bekanntlich geschieht genau dasselbe durch die beiden Ricbtungstheilungen der Eizelle. Auch hier vermehrt sich zuerst die Stbchenzahl auf das Doppelte, um dann durch zwei aufeinander folgende Theilungen auf die halbe Zahl herabgesetzt zu werden. Ueberhaupt weist die Eibildung in ihren Grundzgen genau denselben Entwicklungsgang auf wie die Samenzelle. Die von O. H er t wig fr die Samenentwicklung nachgewiesenen zwei erst...

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1883 edition. Excerpt: ...the soap solution. This is also true of the dilution; but there is no free oil; this is probably what deceived Dr. Riley and Prof. Gillette. They saw this separation, and thought the liquid was not emulsified. Had they tested the diluted emulsion by putting a small piece of paper on top, and then touching the latter upon removal, with a lighted match, they would have quickly found that it was a perfect emulsion. The readiness with which it mixes, upon slight shaking, even years after preparation, is further proof. I have some in our museum made years ago, that is a perfect emulsion today. It is that pronounced against by Dr. Riley. One who has had much experience will be at no loss to distinguish a perfect emulsion as soon aB he adds water to dilute it. If there is free oil it will not mix; if not, it mixes very readily and with very slight agitation. Dr. Riley's emulsion thickens completely, looking like thick cream. This makes it hard to handle, especially in winter, as it must be dipped and cannot be turned from a vessel; but, more, the viscid mass hides the imperfection of the emulsion so that it does not appear till dilution takes place. The diluted emulsion also is more uniform upon standing, except that in all our experiments free kerosene rises to the top, which is less in case soft water is used. Again, my preparation is thoroughly emulsified so that upon any dilution, even with hard water, no free oil rises to the top. Thus it is easily mixed at all times, and may be kept in stock in a dilute or concentrated form for any period. Here again the match test shows that there is no free oil at the top. We have tried a very large number of cases, in all temperatures the past winter, and have not had a single failure. Dr. Riley's...
