as to price and time. Mr. Tolles, loath to undertake the 

 order, was overpersuaded, and in three years, June 2d, 

 1873, handed it over to Dr. Harriman. Mr. Tolles told the 

 writer that he would never make another because of the 

 difficulties, and that only persistent pushing and urging 

 brought forth the one-seventy-fifth. Dr. Harriman avers 

 that the one- seventy-fifth did demonstrate and confirm 

 the presence of axis nerve cylinders in dentine and thus 

 realized its aim. So far as the writer knows, it sustains 

 the claim of Dr. Harriman as the discoverer of nerve fibers 

 in dentine in 1869. 



2. Boston, October 2, 1894. To whom it 7nay concern : 

 This certifies that 1, George B. Harriman of my own ac- 

 cord ordered the late Robert B. Tolles to make me a one- 

 seventy-fifth inch objective in the year 1870 ; that I paid 

 $400 therefor, and I have his receipt; that I ordered it be- 

 cause I wished to verify my discovery of the axis nerve 

 cylinder of the nerves of dentine by using a new mode 

 of sections of dentine as iron is turned in a lathe ; that 

 the one-seventy-fifth inch objective did verify the pres- 

 ence of dentinal nerve tissue fiber ; and that this objec- 

 tive did all I expected it to do and more. 



Signed, George B. Harriman. 



Dr. A. C. Stokes has characterized this objective in his 

 late book thus : "Nothing more miserable can be con- 

 ceived." This being so, then the realization of one's ex- 

 pectations has been generally misunderstood and the 

 English language must be rewritten to suit this new defi- 

 nition of our friend, who wrote as he felt, honestly no 

 doubt, but who will find it hard to change the diction- 

 aries to meet his new definition. 



3. Mr. John Green, of East Boston, Mr. Tolles' first 

 assistant, has allowed the use of the following, Tolles' 

 autographic memorandum of the one-seventy-fifth as 

 follows :
