sufficient guarantee of the scientific spirit and energetic manage- 
ment of the new enterprise, which can scarcely fail, and ought not 
to fail, at the low subscription price of one dollar a year, to receive 
so general a support as to become self-sustaining and perma-

to show an adulterated form actually sold and used, will be 
awarded at the meeting of the American Society of Microscopists, 
next summer. The donor, Mr. E. H. Griffeth, will substitute for 
the medal promised an objective suitably engraved, if preferred 
by the winner. E
