As regards Dr. Beale's doubting or denying all that he is not 

 himself able to show, I venture to recommend to his attention the 

 following sentences : — . ..." seems to conclude, in too many cases, 

 that what he has failed to see does not exist." * Further, " It is pos- 

 sible that for many years to come some observers will persist in 

 terming everything in which they fail to demonstrate distinct struc- 

 ture, connective tissue."! Further, "It is remarkable how posi- 

 tively many authorities deny the existence of structures which they 

 have failed to demonstrate."! And, finally, " Moreover, many ob- 

 servers seem to have determined in their own minds what appear- 

 ance a fibre should present to bo entitled to be regarded as a nerve, 

 and then they arbitrarily assert that a fibre which does not present 

 these characters cannot be nervous ; and even if it be continuous 

 with an undoubted nerve fibre, it is put down as connective tissue."§
