gums that exude from wounds made on various species. 
The Cyrilla Family {Cyrillacece) . 
Case 52. — A small family with but little of economic inter- 
est among its members. Note the wood of the Leatherwood 
(Cyrilla racemiflora) of the southern United States. 
The Bittersweet Family (Celastracece) . 
Case 52. — A family of vines or shrubs usually with bright- 
colored arillaceous fruits of which the Wax Work or Bitter- 
sweet Vine (Celastrus scandens) is a type. The root of this 
species is shown as used in medicine. Observe also the root- 
bark and trunk-bark of the Wahoo or Burning Bush (Euony- 
mils afro pur pur eus) and the fruits of the Bahamian Elceoden- 
dron xylocarpnim. 
The Maple Family (Aceracece) . 
Case 52. — Note the character of the woods of this family 
and the winged seeds of the several species. One of the im- 
portant utilizations of the period is exemplified in the wooden 
plates, so extensively used by pastry-cooks, market men, and 
for picnic purposes. Note Maple Sugar and syrup from the 
vernal sap of the Sugar Maple (Acer saccharum) . Note also 
the use of the wood in the manufacture of type and engraver’s 
blocks. 
The Laurel Family (Lauracece). 
Cases 53 and 54. — The principal products of this important 
family of mostly odorous plants are those exemplified in this 
installation. Observe the various products of the Camphor 
Tree of China and Japan (Cinnamonium camphora), and the 
method of securing this substance. Note that our common Sassa- 
fras belongs to the same natural grouping that includes Cinna- 
mon (Cinamomum seylanicum) , and Cassia Bark and Buds 
from Cinnamonium cassia. The principal edible fruit of the 
family is the tropic Alligator Pear (Persm gratissima). Note 
the various odorous substances yielding oils utilized in per- 
fumery: Puchuri or Sassafras Nuts of Brazil (Nectandra 
Ptichury-minor) , Benzoin from Laurus Benzoin and others.
