Terms. — $3.00 per week for periods of 

 two weeks or less, $1.50 per week for 

 periods of three or four weeks, and $1.00 

 per week for all periods exceeding one 

 month. 



— At a meeting of the Iowa State Med- 

 ical Society a section of microscopy was 

 formed, with the understanding that if a 

 sufficient number of persons interested in 

 microscopy, who are not medical men, 

 should become interested in the matter, 

 to justify the organization of an indepen- 

 dent society, then the section of micro- 

 scopy would resolve itself into an inde- 

 pendent society. 



The next meeting of the Iowa State 

 Medical Society will be held in Dubuque, 

 commencing on the last Wednesday in 

 May, 1881, at 10 o'clock. All persons in- 

 terested in microscopy, whether medical 

 men or not, are hereby invited to come 

 and bring their microscopes, etc., with 

 them. Many men throughout the State 

 have microscopes, but, not considering 

 themselves microscopists, may leave their 

 instruments at hoine. We are all novices 

 in the work, but are trying to cultivate an 

 interest in microscopy. Bring what you 

 have. We wish to have all the micro- 

 scopes we can possibly collect.

MICROSCOPICAL SOCIETIES. 



ONEIDA COUNTY (N. Y.) 



A regular monthly meeting of this So- 

 ciety was held in its rooms, March 28th. 

 The paper of the evening was read by Mr. 

 Mallory. Subject : " The Selection of a 

 Microscope." The reader commenced by 

 saying that to recommend the stands of 

 any one maker, to the exclusion of others, 

 would be a most difficult and thankless 

 task ; not only because of the slight dif- 

 ference in point of excellence between the 

 stands of first-class makers, but also by 

 reason of the new forms of stands yearly 

 designed for special investigation. Then 

 followed a series of hints on the selection 

 of a stand. In regard to objectives, it 

 was, in the opinion of the readers, the 

 best economy to buy first-class objectives 

 at the outset. In conclusion, Mr. Mal- 

 lory advised to buy only the best when 

 you do buy, and take good care of it 

 when you have bought it. An animated 



discussion took place at the close of the 

 paper. Rev. Mr. Whitfield, a manu- 

 facturer of optical instruments, made a 

 few interesting remarks regarding objec- 

 tives, and also spoke of a very ingenious 

 stand he had seen at Troy, made entirely 

 of paper and wood ; he also described a 

 coarse adjustment he had seen at Mr. 

 ToUes in Boston, consisting of two wheels 

 with V-shaped peripherys, at a short dis- 

 tance apart on the same spindle, working 

 into two grooves. The motion communi- 

 cated was very delicate and uniform. 

 The speaker had never seen this adjust- 

 ment on any stand in the market. Dr. 

 Deeke, of the State Lunatic Asylum, de- 

 scribed the large stand now used by him 

 at the Asylum, which was furnished with 

 double rack and pinion, he claimed entire 

 freedom from lost motion, and great ease 

 of movement from this arrangement. 

 Prof. Chester gave a brief description of 

 the most desirable instrument of low 

 price now in the market. A vote of 

 thanks was tendered to Mr. W. H. 

 Walmsley, of Philadelphia, for a gift of 

 his unsurpassed mounted objects, which, 

 in the words of the donor, are intended as 

 the nucleus of a cabinet. Dr. Deeke was 

 appointed to read the next paper before 

 the Society.

FAIRFIELD (IOWA). 



On November 19th, 1880, six gentlemen 

 organized a Society in this city for the 

 study of microscopy, to be called " The 

 Fairfield Microscopical Club." A Con- 

 stitution and By-laws were adopted, and, 

 under the Presidency of Prof. Albert 

 McCala, of Parson's College, interesting 

 monthly meetings have been held. The 

 Club is quite prosperous. 



At the March meeting a number of 

 visitors were present. Prof. Wm. Lighton 

 opened the evening with a selection from 

 Chopin on the piano. After the usual 

 business was transacted, a paper on " The 

 Relation of Microscopy to the Study and 

 Practice of Medicine," was read by Dr. 

 R. J. Mohr. 



A number of objects, mounted by Dr. 

 Mohr, were then exhibited on the various 

 stands, in illustration of the paper of the 

 evening. 



Dr. Mohr also exhibited a Bulloch's 

 Congress Stand.
