«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, b andc). 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 botan- 
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 of 
wood cut across the grain, are 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 
sample cards sent upon application. Address
