262 OF THE NERVE-TUFTS, NERVE-EMINENCES, ETC, 



"bodies first studied by Kollikei' in the breast-muscle 

 of the frog, which are referred to in p. 269. I have 

 never been able to demonstrate such bodies as I am 

 about to describe in the muscles of animals generally, 

 although they are exceedingly distinct in the muscles 

 of lizards, as shown by Rouget. I have demon- 

 strated many in the cutaneous muscles of the neck, 

 and in the muscles of the tongue of the chameleon, 

 and shall carefully consider the structure of tliese. 



In the first place, I would remark that these bodies 

 are external to the sarcolemma, though adhering inti- 

 mately to it, as may be proved by examination of the 

 the specimens. The course of the nerves to and fro'tii 

 these bodies, PL XII, fig. 2 ; PI. XIII, figs. 1,"2, 3, 

 renders it almost impossible that they could be beneath 

 the sarcolemma, while in many cases the outline of 

 the sarcolemma can be followed underneath them. 

 Secondly, it appears probable that they are a re- 

 duplication and expansion of continuous fibres, rather 

 than terminal organs formed upon the extremities of 

 the nerve- fibres ; nor would it seem that these orsrans 

 are essential to the action of nerves upon muscle, 

 since they are only to be demonstrated in the muscles 

 of certain animals. Moreover, as raany diSerent 

 forms of these nerve organs are to be seen in a small 

 piece of muscle, exhibiting different degrees of com- 

 plexity, we may perhaps by studying them attentively 

 be able to draw a true inference as to their real struc- 

 ture, and the mode of their formation. PI. XII, fig. 2. 



Kilhne's idea of the structure of these bodies is re- 

 presented in the figures copied from his memoirs (PI. 

 IX, fig. 3 ; PI. X, figs. 2, 3, 4). The interpretation of 

 the appearances here given is totally difierent from 

 that which I have been led to offer. In my specimens 

 the nerve-fibres entering into the formation of these 

 tufts are seen to divide and subdivide into several 

 branches which are folded, as it were, upon one 

 another, PL XIII, figs. 1 and 2, The nuclei seem to
