Present, Dr. Girdwood, President, in the chair, Senator 
Murphy, Dr. Sterling, and Messrs. Stevenson, Geo. Sum- 
ner, Richards, Learmont, Chambers, Beaudry, Johnston, 
Gardner, Lovejoy, Shaw. The minutes of last meeting 
were read and confirmed. 
At the request of the President, Dr.Wyatt Johnston then 
read an exceedingly interesting paper, his subject being 
the ‘‘ Microscope in Medicine.” He began by saying that 
it was about 30 years since the microscope began to be used 
in the investigation of different diseases to which humanity 
was subject, and by its aid an immense amount of light had 
been thrown upon what was now termed the germ theory. 
In such diseases as tuberculosis, heart disease, la grippe and 
others, the bacilli in the sputum could be recognized by the 
aid of the microscope, and the practitioner was greatly as- 
sisted in diagnosing his case. Through the same instrumen- 
tality it had been proved that dysentery was caused by an 
intestinal parasite, and the discovery of the common bacillus 
of cholera was also due to its power. In the examination of 
blood it was shown to be invaluable; it not only revealed its 
condition, but often assisted the physician to locate disease 
when other methods failed. 
Great interest was manifested in the experiments which 
followed, as Dr. Johnston gave practical illustrations of the 
methods employed in the examination of blood. 
At the close of the lecture the members present joined in 
a general discussion of the subject, and before adjourning a 
very hearty vote of thanks was tendered to Dr. Johnston for 
his interesting lecture. 
The President then announced that the last lecture of the 
season would be delivered by J. B. McConnell, Esq., M.D., 
C.M., subject, “ Normal Histology of the Brain and Spinal 
Cord.” 
The meeting then adjourned.
