«American Woods, 
a publication relating to American woods, and in which each is represented — 
by actual and authentic specimens so prepared as to show transverse, radial and © 
tangential views of the grain (see figures a, ) and). The specimens are so thin — 
as to allow the transmission of light, and thus the characteristic structure of each — 
is beautifully shown. Accompanying text gives full information as to the dotan- 
ical characters, habitat, physical and medicinal properties, uses, etc. The speci-— 
mens and text are gathered together into neat cases resembling handsomely — 
bound octavo volumes, each one representing twenty-five species, having at least — 
seventy-five specimens, and selling at $5.00, expressage paid. 
PREPARATIONS OF WOODS FOR STEREOPTICON AND MICRO- 
SCOPE.—These are perfect in every way, elegantly prepared and accurately 
labeled. 
WOODEN CROSS-SECTION CARDS.—The toughness and ivory-like 
smoothness of these cards, especially when we consider that they are sections fe 
wood cut across the grain, ave a surprise to everyone. Being perfectly adapted to : 
printing, India ink work, painting, etc., they are very choice and valuable for — 
advertising cards, invitations, calling cards, dinner cards, etc. Circulars and
