250 kolliker's conclusions. 



receiving, as is affirmed, nervous supply at one single 

 point only — I Lave been led to conclude that every 

 muscular fibre is crossed by very delicate nerve-fibres, 

 frequently, and at short intervals, the intervals varying 

 much in different cases, but, I believe, never being of 

 greater extent than the intervals between the capillary 

 vessels. 



27'?. Kolliker's conclusions. — With regard to the 

 ultimate arrangement of nerves in muscle, the conclu- 

 sions of Kolliker accord more nearly with my own 

 than those of any other observer. (Compare Kolli- 

 ker's statements in liis Croonian Lecture delivered in 

 1862, with the results stated in my paper, published 

 in the Phu. Trans, for 1860.) KolHker agrees with, 

 me in the opinion that the nerves lie upon the ex- 

 ternal surface of the sarcolemma; but what he re- 

 gards as ends or natural terriiinations^ I believe to be 

 mere breaks or interruptions in fibres which, in their 

 natural state were prolonged continuously, PI. X, 

 fig. 1. 



218. Kiiline's views. — My friend Kiihne, of Heidel- 

 berg, has probably published more papers upon this 

 vexed question than any other observer. He maintains 

 that the nerve always passes through the sarcolemma 

 and comes into direct contact with the contractile 

 tissue,* or ends in protoplasmic matter which is in 

 continuity with the muscle, PI. X, figs. 3 and 4. He 

 has, however, from time to time been led to modify 

 bis view very materially, as th.e figures in his various 

 memoirs, published between the years 1859 and 1864, 

 will testify, PI. IX, fig. 3, PI. X, figs. 2, 4, 5. In his 

 memoir, published in 1862, he described minutely the 

 structure of some very peculiar organs, which he stated 

 had been demonstrated by him in connexion with the 



* This view was first advanced by Kiihne in 1859 (" TJnter- 

 suchungen iiber Bewegimgen und Veranderungen der contrac- 

 tilen Substanzen," Reichert und Du Bois Reymond's Archiv, 

 1860).
