a fossil and recent product utilized in varnish making. Note 
Chiga starch from the seed of Campsiandra comosa; and the 
characteristic wood in this family. 
Cases 61 and 62. — Various seeds of the Bean Family. Note 
the wide geographic range of the common Bean (Phaseolus vul-

daily with the variations in temperature within the case ; it 
solidifies entirely at 57° Fahrenheit. Note the rosary made of 
the dried “hips” of our common wild rose (Rosa canina) thus 
originating the name “Rosary”; the native candle made of the 
kernels of the Pigeon Plum (Chrysobalanus icaco) ; the pre- 
served rose petals and dried prune roll of Bulgaria.
