326 PROCEEDINGS OF SOCIETIES. [^ZV'Sll. May Eisef 
Sciences, January 26, W. W. Allport, D.D.S., was elected President; 
James Hankey, Vice-President; Henry E. Munroe, Esq., Treasurer. 
In stating the object of the meeting, the President said that the 
existence of a nucleus in blood corpuscles has been long a question 
with histologists. Such distinguished men as Drs. Carpenter, Dalton, 
Peasley, Wharton Jones, Kolliker, Bennett, Beale, and McDonald, 
have denied their existence. Virchow is the only author who has 
strongly inclined to the opinion of their existence, and he simply 
assumes the fact without clearly demonstrating it. Within the last 
twelvemonths Prof. Ereer has discovered in these corpuscles characters 
which have never before been mentioned by any author on human 
histology. In his recent visit to Europe, he exhibited their structure 
to Prof. Hughes Bennett, of Edinburgh, who subsequently stated to a 
physician of Chicago, that Prof. Ereer had presented to him characters 
in the blood cells which he had never before witnessed. Other pro- 
minent European histologists made the same frank acknowledgment. 
If what Dr. Ereer should exhibit shall prove to be the real nuclei of 
the blood cells, it Avill be sufficient to hand his name down in the 
history of medicine as the discoverer of what has long been sought, 
but never before found. 
Prof. Ereer, in presenting the subject of the evening, said that 
histologists acknowledge the existence of a nucleus in the reptilian 
blood-cells. He had always believed the blood cells of warm-blooded 
animals nucleated also. When viewed by transmitted light the 
structure is lost, and it is only when shown by reflected light as an 
opaque object — which he was able to do by the use of an illuminator, 
invented and patented by Prof. H. L. Smith, of Geneva, N.Y, — that 
the anatomical structure of the cell is truly exhibited. This shows 
the cell as a bi-concave disc, with the nucleus appearing as a promi- 
nence in the centre. He did not make this as a positive assertion, but 
exhibited the object, and left scientific men to draw their own infer- 
ences. 
Dr. S. J. Jones stated that he saw Prof. Bennett subsequently to 
his meeting with Prof. Ereer, and that Prof. Bennett expressed his 
high satisfaction with the presentation of the cells which Prof. Ereer 
made. 
The Club then proceeded to inspect the corpuscles, and, subse- 
quently, other interesting preparations made by Dr. W. C. Hunt. 
After a brief discussion of the points presented, and the adoption 
of a vote of thanks to Prof. Ereer and Dr. Hunt for the gratification 
received, the Club adjourned.
