Alumni Association of the Detroit College of Medicine; Annual 

 Report, 1888. 



This is the first comprehensive report ever issued by the Alumni of 



this College, and v^ill do much to advance the interests of their alma 



mater, as it contains full records of the college work done during the 



past year. The interests of a college demand the interests of its alumni, 



and we hope its association will continue to feel the interest so fully 



shown in the report before us. 



To improvements in the construction of the microscope and its 

 use are due in a great measure the important advance in our 

 knowledge of the internal structure and development of plants and 

 their parts. — Western Druggist. 



CORRESPONDENCE AND QUERIES. 



To the Editors of The Microscope : 



In the April number of The Microscope, there appeared a part 

 of a personal report entitled " Note on a Fasoldt Test-Plate," by 

 R. H. Ward, M. D., of Troy, N. Y., member of the committee 

 appointed by the American Society of Microscopists to examine the 

 test-plate made and presented to the Society by the vsriter. Not 

 being in harmony with the assertions made in this report, I wish to 

 make some remarks regarding it. 



Ai the first examination. Dr. Ward, E. C. Fasoldt and myself 

 were present, and at the last and most important, the above 

 mentioned, and two gentlemen whom Dr. Ward brought with him, 

 and Dr. T. F. C. Van Allen. Of the latter gentleman Dr. Ward 

 makes no mention, but who, however resolved every band up to and 

 including the 200,000 lines per inch in the presence of Dr. Ward, 

 and who also accomplished it a number of times before. Dr. Ward 

 having told me on the first occasion that his eyes were ruined from 

 overwork, I asked Dr. Van Allen to be present at this final examina- 

 tion, to which he kindly consented. 



In the report it is said that my son, Ernest C, could see 130, 

 000 lines per inch, " and none beyond that." It is a grave mistake 

 for the Doctor to make such an assertion, as my son said, after he 

 had brought the lines in the field : '' Doctor, here are the 130,000."
