time to time, confirm. m.e in the truth of the general 

 views I have advanced on the arrangement of nerves 

 in peripheral organs. That an observer should assert 

 that in muscle the dark-bordered nerve fibres end 

 almost abruptly in the nerve plates, and yet hold 

 that in other tissues the ultimate nerve fibres are so 

 minute that many pass into a single epithelial cell 

 is most remarkable ; but nevertheless many German 

 anatomists, undoubtedly, having great authority, 

 maintain that there is nothing inconsistent in accep- 

 ing both statements, an opinion which could not, I 

 think, be adopted by any one who had succeeded in 

 following, as I have done, in several different tissues 

 of the frog, newt, and other animals the fine ramifi- 

 cations of the pale nucleated nerve fibres. [1868.]
