AT THE DOCTOR’S EXPENSE. 
Dr. Oliver Wendell Holmes calls the dissection room the 
“Anthropotomic laboratory.” . The word probably only applies to 
Boston. 
There is a rumor from Germany that a learned chemist has dis- 
covered a wonderful oil that will restore youth to old age, etc. It 
must be a species of O-live oil.— Philadelphia Bulletin. 
“There is nothing very brilliant about our Bremen dentists,” 
said a lady to a member of the profession in Berlin, “but they are 
very obliging. If you wish a tooth extracted with gas, they forth- 
with light the chandelier.” [Exc.] 
“Diaploma,” “diplomy,” ‘“diplomer,” “diplomah,” “diaplemy,” 
“diopluma,” “dipluma:” These are seven different ways, according 
to the files of their State Board of Health, in which Illinois doctors 
spell the name of the instrument which gives them authority to 
practice medicine. Let it be hoped that their slaughter may be con- 
fined to the Queen’s English.

Porassic IopIpDE FOR PRESERVING INFUsoRIA.—Mr. W. S. 
Kent has found potassic iodide to act in a manner almost identical 
with osmic acid, and in some instances even more efficiently. The 
medium possesses the additional advantage of yielding no deleter- 
ious exhalations, which have to be carefully guarded against in the 
use of osmic acid. The formula for preparation is as follows:— 
Prepare a saturated solution of potassic iodide in distilled water. 
Saturate this solution with iodine, filter, and dilute to a brown sherry 
color. 
A very small portion only of the fluid is to be added to that 
containing the infusoria.
