HIGH ANGLES OR LOW ANGLES? 
We sent two objectives to a young physician who ‘ wanted 
one that would do the best work for an active physician who 
had no time to fuss but plenty of time to spend profitably.” 
One objective was a one-fourth of over a hundred degrees aper- 
ture and the other was a one fourth of about seventy-five de- 
grees. Our friend returned the one-fourth of one hundred 
degrees and retained the one of seventy-five. ‘The one I 
keep,” said he, “‘ has much the better working distance; shows 
the larger crystals of uric acid better, and defines the smallest 
oxalates just as well. You do not tell me which you think is 
the better glass, nor which is worth the more, but for a doctor I 
am sure I have chosen wisely.” But Dr. J. Edwards Smith 
would tell him, in all probability, that he was not competent to 
judge, and that after proper education and “ eye-training” he 
would see the error of his ways and would hasten to get a half 
inch mortar-objective with Butterfield screw.

A LIFE PRESERVATIVE. 
We understand that the well-known proprietor of a certain 
wonderful patent-medicine, made at Rochester, N. Y., is about 
to issue a circular which he will distribute to the members of 
the American Society at their first meeting. This circular wil 
state, among other things, that—‘ if you will take from four 
to six bottles during the next three or four months it will 
so fully invigorate the system you will be enabled to prolong 
your life sufficiently to see a printed copy of your proceedings 
for 1&84.”

one evening to a very attentive listener. He explained one 
peculiar feature after another with his usual flow of graceful
