ITS UNIQUK POSITION. 



Paris. — No word has come from Paris that anything like 

 th s ohjeclive has been made in France. The French accord this 

 precetlence to America, and }>ronounced the photographs from 

 this ohjeclive as not inferior to any ever taken. 



London. — In 1SS9, a re|)resentative of Mes^;. PowelKt Lealand 

 looked through the 1-T5th, expressed satisfaction in its perform- 

 ance and gave Mr. Tolles the highest compliments. lie said he 

 had made a 1-SOth, but that it was not ])ractically useful. In 

 1890, an P^nglishman in Berlin told me that photographs had 

 been taken with the l-80th but this does not annul the priority

The following incident gives a bit of evidence. In 18S9, call-

 were shown. All his icy demeanor melted away into the most 

 genial, warm, cordial and even efi'usive politeness. In the same 

 year the following saw the objective and its work, conceding its 

 position. Sir Morell Mackenzie, Surgeon General Mackinnon, 

 the highest medical official of the British Army ; hisstaffat the 

 war office; the Lord Mayor, 1889-1890; the medical mess at 

 Aldershot; Assistant Professor Lennox of the Royal Institution, 

 the Society of Science, Letters and Art. 



Berlin. — In 1890, said the representative of one of the larg- 

 est German microscope manufacturies, after seeing red blood 

 corpuscles demonstrated by this objective and its stand from 

 Boston : '' Doctor, I thank you very much for this s])lendid 

 exhibition. It is the event of my life. I never saw such instru- 

 ments before. We don't make them as they will not pay for 

 them." 



Vienna. — Here is a letter from Dr. Kohler, written to me on 

 January 29lh, 1891, in which he says : " The undersigned, who
