out success with all the most difficult 

 ones. In this work, especially relating 

 to ruled lines, he devised methods and 

 apparatus, much of which he constructed 

 himself, by which success was greatly 

 facilitated. None of his early devices 

 were published by him, but some have 

 been credited to other less modest inves- 

 tigators. 



His best known invention relating to 

 the resolution of tests was the plating of 

 micrometer lines with silver, by which 

 method the difficulty of resolution was 

 so much decreased that one of the best 

 known microscopists described the result 

 as " altogether too easy to be interesting." 

 By this method Dr. Rezner succeeded in 

 resolving the famous band of 120,000 

 lines to the inch, which resolution he was 

 the first to accomplish, and which he ex- 

 hibited at the Buffalo meeting of the 

 American Society of Microscopists, and 

 this method has since had extensive ap- 

 plication. Dr. Rezner devised and con- 

 structed a special traversing apparatus 

 for use in the resolution of lined tests, 

 and among other devices an improved 

 fitting with universal movements for the 

 Wenham reflex illuminator. He person- 

 ally constructed several different forms of 

 the Wenham reflex illuminator, numerous 

 solid oculars, immersion illuminators, and 

 various prisms and special fittings of 

 many kinds, for use in special investiga- 

 tions in which he was from time to time 

 engaged. His form of mechanical finger 

 is widely known and used, and is the 

 most generally available of any form yet 

 described. Various other forms of micro- 

 scopical apparatus in common use were 

 modified and improved upon by him, and 

 he had but lately constructed a spectro- 

 scope and spectroscopic apparatus, upon 

 which he contemplated still further im- 

 provement, when death cut short his use- 

 ful life. 



"But we mourn not only our president, 

 but also the loss of a faithful friend. His 

 cordial and genial manner endeared him 

 to all, and the remembrance of his 

 patient attention to all discussions and 

 suggestions, and the modest manner in 

 which he always presented the results of 

 his own ripe experience, will remain with 

 us as worthy of the man and of our imi- 

 tation. Notwithstanding his modest and 

 unassuming manner, he was a man of de- 

 cided views and firm convictions ; his 

 opinions, though not vaunted, were the 

 result of careful thought and were not 

 easily changed. Of deep religious con- 



victions and the most rigid and refined 

 integrity. Dr. Rezner, was, in social life, 

 the soul of wit and mirth, and was one 

 of the most enjoyable companions that 

 could be found. His circle of acquaint- 

 ance was unusually large, and he was so 

 universally esteemed by all who knew 

 him, that it may be truly said he had no 

 enemies, for his political adversaries, 

 while opposing, yet admired and respected 

 him. 



" In his professional life he was a warm 

 friend alike to his brethren and his 

 patients. He was ever ready with aid 

 and advice to the younger members of 

 the profession, many of whom he has 

 guided to a successful and honorable 

 career, and by even the most talented of 

 his brother physicians his advice was 

 sought and availed of. To his patients 

 he was endeared by all his noble quahties 

 of heart and mind so deeply, that many 

 homes besides his own now feel the deso- 

 lation of his removal. To his bereaved 

 family our stricken hearts go out in sym- 

 pathy, and with them we mourn in common 

 the loss of one not only endeared to us 

 by every memory, but who has proved to 

 us our chief dependence and stay. To 

 us, as to them, his loss is irreparable, and 

 we bow in sorrow to the manifestation of 

 that providence of Him whose will our 

 departed friend ever deemed his guide, 

 and whose protecting care and watchful 

 guidance we prayerfully invoke for them." 



To THE Editor : 



Dear Sir : — As a worker in micro- 

 scopy in my humble way, I wish to say a 

 few words on the matter of American and 

 German lists of objectives. Let us say, 

 I want a 2-inch glass. I, of course, want 

 a good glass; in fact, I want a perfect im- 

 age. I send to an American maker of 

 repute for his list. What do 1 find? 

 2-inch $25.00 or $30.00. I look at a Ger- 

 man list : I see a first class 2-inch, $7,00 

 or $8.00. Is it a wonder if reason is con- 

 founded? Why, if a first class 2-inch is 

 worth $25.00, this German maker is a fool 

 or a liar. But, no, he can be neither, see- 

 ing he is a maker of wide repute ; his 

 glasses must be good ! they are used in 

 some of the first institutions of learning in 

 the world ! Admited his 2-inch at $7.00 is 

 a good glass, what can it possibly be that 

 makes the American 2-inch worth $25.00? 

 What can a man see with a 2-inch to jus- 

 tify such an outlay? These are some of 

 the thoughts begotten by a survey of 

 these respective lists. 



Something is wrong here. What is it?
