ARRANGEMENT OF NERVE FIBRES. 43 



ramifications we can see under the highest 

 powers yet made (the -$ and -g^ magnifying 

 respectively 1,800 and 2,800 diameters). The 

 arrangement in question is represented in a 

 great number of my drawings published during 

 the last thirteen years. And yet some of the 

 most careful observers seem unacquainted with 

 the fact, and not aware that attention has been 

 directed to it. In truth they contradict obser- 

 vations, the correctness of which can be put to 

 the test by the examination of a good specimen 

 in five minutes. * 



* Some elaborate and otherwise very correct drawings in 

 the very last number of Max Schultze's " Archiv," are 

 defective in this particular. In the very large drawings the 

 nerve fibres composing the fine compound ramifications are 

 represented by parallel lines ("Die Flughaut der Fledermause, 

 namentlich die Endigung ihrer Nerven," von Dr. Jos. 

 Schobl, in Prag. Siebenter Band, Erstes. Heft, 1870). This 

 paper is a very valuable one, and is particularly interesting 

 to me, inasmuch as the author confirms many of my own 

 observations concerning the ultimate distribution of nerve 

 fibres, which were made several years ago, and were at that 

 time discredited in Germany. The networks of fine fibres 

 described and figured in several of my papers, and illus- 

 trated in Plates I and II of this essay, are represented by 

 Schobl in three colours over a very extensive surface of 

 tissue. The author's delineation of the distribution of 

 nerves to muscle also accords with my own. Dr. Schobl will,
