SUPPLEMENT. 



CONTRIBUTION'S TO THE CINCINNATI MEDICAL NEWS. 



Inasmuch as the author's contributions during the past six 

 years to the pages of the Cincinnati Medical News, and also the 

 American Journal of Microscopy contain instructions more or 

 less interesting to those commencing the study of the micro- 

 scope, it is thought desirable to present them in this supplement. 

 It was however found on inquiry that the back numbers ot the 

 Cincinnati journal were not to be obtained. 



Dr. Blackham, of Dunkirk, N. Y., kindly placed his bound 

 volumes of the News in the hands of the writer, thus enabling 

 him to give the reader the following references, dates, etc., to 

 the several articles contained in the Medical News.
