THE AMEKICAN MONTHLY. 



[June. 



assert he made them, is more than I can 

 understand. 



I want to see a sworn copy of the draw- 

 ings or sketches made previous to August, 

 1883, and also the oaths of two credible 

 witnesses who saw them previous to Au- 

 gust, 1883. I want no thinking such is 

 the drawing, but proof. 



As 1 have several samples of adapters 

 very much like the one which Prof. Mc- 

 Calla shows in fig. 13, page 66, 1 will free- 

 ly give one to any person who is interest- 

 ed and will send for it, for they are much 

 more trouble to insert in the instrument 

 than objectives with the society screw, for 

 the reason there is no guide to find the en- 

 trance or position of the slots, in the im- 

 provement of which lies one of the chief 

 points of my nose-piece. 



If Prof. McCalla had perfected his idea 

 and fully demonstrated that his invention 

 was a success, is it not reasonable to ex- 

 pect he would have brought his drawings 

 and description to the Chicago meeting, 

 more especially as he intended to make 

 special reference to such a device ? But 

 now, after sleeping over his crude idea for 

 three years, and waiting until some other 

 person puts it into practical shape, he has 

 found ample time to make drawings and 

 to write a description of it. 



Walter H. Bulloch. 



[Mr. Bulloch encloses with the above 

 communication a sworn statement, de- 

 claring that ' Prof. McCalla never showed 

 any drawings or sketches in my presence 

 at Detroit or any other place, and that he 

 never mentioned the subject in my hear- 

 ing, excepting as given in my letter in the 

 March number,' etc. 



We trust this unfortunate controversy 

 will be speedily brought to a close, but 

 having gone thus far we cannot in justice 

 to either party bring it to an abrupt end 

 here. We think, however, that Mr. Bul- 

 loch has stated his case at length, and un- 

 less new developments render it neces- 

 sary, as a matter of justice, that more 

 should be added by him. Prof. McCalla's 

 reply, if he chooses to make one, should 

 end the controversy, which we vainly en- 

 deavored to prevent when its first mutter- 

 ings were heard. It is but right for us to 

 state, however, that Prof. McCalla sent 

 us his first drawings for publication on 

 the 28th of January, and in a letter of that 

 date he wrote as follows : ' I can and do 

 solemnly affirm that they are exact copies 

 (except as to enlargement of scale) of my 

 original drawings made in July, 1880, 

 drawn with more care and accuracy, but 

 not changed in any way.' — Ed.]

' The philosophy of this work is based 

 on the theory that there is a special and very 

 important and very frequent clinical va- 

 riety of neurasthenia (nervous exhaustion) 

 to which the term sexual neurasthenia may 

 properly be applied. While this variety 

 may be and often is involved as cause or 

 effect or coincident with other varieties — 

 exhaustion of the brain, of the spine, of 

 the stomach and digestive system — yet in 

 its full development it can be and should 

 be differentiated from hysteria, simple hy- 

 pochondria, insanity, and various organic 

 diseases of the nervous system, with all 

 of which it had until lately been con- 

 founded.'
