Spondias mangifera.—The gam exudes instalactiform 
eces of a yellowish or reddish-brown colour and witha smooth 
ining surface. It forms a gelatinous mucilage with a large 
lume of water. The mucilage is precipitated by acetate of 
lead, gelatinized by the basic acetate and by ferric chloride, but 
not by borax. 
Poinciana regia yields a gum in irregular granular or 
rty tears of a yellowish or reddish brown- colour soluble in” 
water, forming a thick opalescent mucilage. The solution is 
latinized by basic acetate of lead and ferric chloride, but not 
the neutral acetate nor by borax. Fehling’s solution is

The surface of some of the tears is of an opaque

attempt to arrange themselves into bundles of acicular crystals.
