THE MICROSCOPE. 251 
the Executive Committee of the International Exhibition of Geo- 
graphical, Commercial and Industrial Botany at Antwerp in 1890. 
A retrospective exhibition will be got together from all available 
quarters, illustrating the history of the microscope, as well as an 
exhibition of the modern instruments of existing workers. A variety 
of conferences relating to technical and _ scientific questions 
connected with the microscope will be arranged. Already great 
interest is being expressed in the proposed exhibition. 
NEWS,AND NOTES. 
Dr. Pavt B. Barrincer, of Davidson College, N. C., has been 
elected to the chair of Physiology and Surgery at the University of 
Virginia. Dr. Ballinger is a well-known microscopist, and in his 
new field will undoubtedly be able to accomplish much in this de- 
partment of science. 
Dr. Frank L. James, in St. Louis Medical and Surgical Jour- 
nal, says: I believe that the Elder Spencer, who soon followed his 
friend Tolles to the silent land, was as good as Tolles. I believe 
further that his son Herbert Spencer, is second to no living optician. 
That Gundlach has produced and is producing objectives, the ex- 
cellence of which cannot be duplicated in Europe to-day, and that 
for certain grades of objectives, those of Bausch and Lomb are ab- 
solutely incomparable. American opticians have absolutely nothing 
to fear in competitive contests, so far as excellence of work goes, 
with any in the world. I have no patience with Americans who are 
sending abroad for microscopes and objectives. They can get better 
at home for the same expenditure of money. 
Dr. GaMALEIA is said to have offered to resume his former 
position as director of the Bacteriological Station at Odessa. The 
authorities have declined. 
From what has been accomplished recently in microscopy in 
revealing the hidden forces of nature, through all the imperceptible 
gradations of birth, development, life; and on the other hand the 
processes of retrograde metamorphosis, destruction, death; the 
dental profession preéminently has reason to congratulate itself 
upon the possession of so many skilled workers in this special field 
of study. The importance of the microscope in dentistry has never 
been felt so strongly as at present. The perfection of its machinery 
which enables a microscopist to confirm the truths of his patient re- 
search to a whole room-full of people at once, is a wonderful step in 
advance.—President’s address, Michigan Dental Association, 1889.
