Case 417. — Note the Lignum Vitae or Palo Santo (Bulnesia 
sarmienti) noted for its interlacing tissue, forming wood that is 
very hard indeed to split or splinter. 
Case 418. — Note the two beautiful red woods Cedro na Pyta 
(Trichilia canjerana) and Quebracho (Quebrachia balansce), the 
latter of which yields a very valuable tanning kino. 
Case 419. — Observe the peculiar form and structural beauty 
of the Ivira Pepe Colorado {Holocalyx balansce), a red dye- 
wood belonging to the Bean Family. 
Case 420. — Note the clear yellow wood of Rabo de Macaco, 
an unidentified member of the Bean Family and the rose colored, 
hard wood of Ivira Pyta {Peltophorum Vogelianum) , 
Case 421. — All the specimens in this case are of more than 
ordinary interest; the dye-wood Guayacan (Caesalpina melano- 
car pa), the clean, clear, yellow Abati Timbabi (Hymenaea stil- 
bocarpa), the dark striped red wood, Curupay (Piptadenia rigida) 
and the similarly marked and colored Curupay Ata (P. cebil). 
Case 422.— Note the two bright rose-pink woods Curupay Mi 
(Stryphnodendron sp.) and Curupay Na {Piptadenia rigida). 
Case 423.— Note the beautiful, clear white wood of the Palo 
Blanco (Calycophyllum multiflorum) and the two dark red Mes- 
quites: Algarobo negro {Prosopis nigra) and Algarobo rojo 
(Prosopis sp.). 
Case 424.— Note the clear, white, firm wood of the white Que- 
bracho {Aspidospermum quebracho-bianco) . 
Case 425. — The clear, clean, yellow wood of the White Lance- 
wood, Palo de Lanza Blanco {Myrsine Grisebachii) and the 
greenish-brown, hard and firm Lepacho Negro (Tabebuia flave- 
scens) are the most striking specimens in this case. 
Cases 426 and 427. — These cases contain several striking and 
interesting woods, among them the only South American willow 
{Salix Humboldtiana) ; the Southern Coconut {Cocos australis) 
and the Mora {Madura Mora) one of the valuable South Amer- 
ican dye-woods, similar to fustic. 
Cases 428 and 429. — These cases display several tree cross 
sections which illustrate the density and slowness of growth of 
several species. Notable in Case 428 is the peculiar cross section 
of the Ibira Pepe Morati {Holocalyx balansce) and the bright 
rose-colored wood of Quebracho Rubia, a form of Quebracho bal- 
ansce. In Case 429 are notable the wood of a great Elder tree
