detail of structure. Mr. Hanks had examined the cast closely with the 

 microscope, and could find no trace of charcoal. Nor can it be pos- 

 sible that the rock was hot, for had the cone been burned the fine stria- 

 tions could not have been so perfectly preserved. It is Mr. Hank's 

 intention to study these rocks microscopically, and report to the society 

 the results of his further researches. 



In view of the prominence given to the question of the discovery of 

 the microscope, and the celebration of the three hundredth anniversary 

 soon to take place in Antwerp, Mr. Riedy exhibited an old book by 

 Petro Barello, published at The Hague in 1655, entitled " A History 

 of the Telescope and the Microscope." This old book is remarkable 

 as being the first published work treating of the discovery. 



June 4^ i8gi. — After discussing the refreshments furnished and drink- 

 ing the success of the society, the audience was called to order by Pres- 

 ident Wickson, who called attention to the fact that the society had 

 reached its majority, having been founded June 4, 1870. He spoke 

 bjiefly of its career, alluded to its vicissitudes and pointed with pride 

 to its success. The Committee had prepared a list of sentiments which 

 he would proceed to announce. 



" The Birth of the Society" was responded toby Dr. S. M. Mouser, 

 who had watched over its early development and growth, from the time 

 it cast its swaddling clothes imtil its present vigorous maturity. 



"Our Coming of Age " was very happily treated by Colonel C. 

 Mason Kinne, who was one of the original six who met together ex- 

 actly twenty-one years before and laid the foundations. He regretted 

 that he alone of that number was present on this occasion. The early 

 members were poor but ambitious, and one object of those who origin- 

 ated the society was the purchase of a first-class microscope and acces- 

 sories, something the individuals could not aflibrd. 



"The Microscope in Medicine" was responded to by one of the 

 veterans — Dr. J. H. Wythe. He alluded to the fact that his first mi- 

 croscope was purchased fifty-five years ago, and that as a result of his 

 earlier investigations with the instrument, he had prepared a paper on 

 Bright's disease, which he read before a county medical society to 

 which he belonged in Central Pennsylvania. Some of the old physi- 

 cians who listened to it said they had always diagnosed diseases without 

 a microscope, and could see nothing to be gained by calling in its aid, 

 at the same time advising the young medico to " go slow." 



Dr. M. C. O'Toole responded to the sentiment of " Brass and Glass " 

 in a very witty little speech, which was received with every mark of 

 appreciation. 



The President next announced " The Microscope in Relation to the 

 Point in Dispute," which was responded to by ex- Judge Rearden. He 

 alluded to Cicero's words, where he speaks of the kinship existing be- 

 tween all professions, and how science has ever had the respect of the 

 legal fraternity. In courts of justice scientific experts always command 

 the respect of bench, bar, and jury. In view of the wonderful discov- 

 eries made by scientists, especially the discoveries of the past twenty 

 years, showing the intimate relations of micro-organisms and disease, 

 the Judge ventured to remark that coming generations might demon- 

 strate that all human impulses were controlled by the presence or ab- 

 sence of certain forms of bacilli. The ardent swain of the twentieth
