Tolles' Monument. 



On Tuesday, May 17, 1898, at 3 o'clock p. m., 15 years 

 after his death, friends gathered at Mount Auburn, Bos. 

 ton's noted cemetery, to dedicate the monument that had 

 been recently erected over the grave of Robert B. Tolles. 

 The pedestal is perhaps 18 inches by 36 inches, rising 

 perhaps 9 or 10 inches from the ground. Upon this a 

 large rectangular block of granite is placed, it having 

 about twice the length that it has height or thickness.

 words: "Erected by the New England Association of Op- 

 ticians to the memory of Robert B. Tolles, 1823-1883." 



The monument was paid for by opticians and not by 

 microscopists. In the list of 62 contributors we find, 

 however, the names of W. G. Corthell, H. M. Dunham, 

 R. J. Nunn, M. D. and A. M. Wentworth, who are appar-

 was made by and in the name of the New England Asso-

 aloof from honoring the name of Tolles is as mysterious
