272. Distribution of nerves to the muscular fibres 

 and other tissues in the bladder of the frog. — For 



the demonstration of the nltimate arrangement of 

 the most minute nerve-fibres, there are very fevs^ 

 textures which possess so many advantages as the 

 bladder of the frog. It is so thin and transparent, 

 that it may be regarded as a natural dissection and 

 thinning-out of some of the most delicate tissues. 

 The unstriped muscular fibres of this organ are ex- 

 tremely fine, and in many places are well separated 

 from one another, so that fine nerve-fibres can be 

 very distinctly seen in the intervals between them.

With regard to the presence of nerve-fibres in 

 involuntary muscle generally, I wo aid remark that 

 I have demonstrated fine nerve-fibres in so many 

 different cases, that it is more in accordance with the
