where it is spread before sowing, no advantage was secured as compared 

 with manuring the potato with sulphate of ammonia alone. 



For a more accurate interpretation of the results of these tests, it should 

 not be forgotten that the spring and the first half of the summer were 

 very dry. 



8()4 - Wild Oil Plants of Para, Brazil. — C7i«c«ms c Quintacs, Voi. xiii, No. 5, pp. 322-323- 

 S. Paulo, Ma J- 15, 191 6. 



Mr. C. PescE, of Cameta, Para, Brazil, has for several years been study- 

 ing the oil seeds of the forests and islands in the estuary of the Amazon. 

 He reports the following species, which he uses in his factory of vegetable 

 oils and soaps, and of which he exports jDart to Europe. This list j^roves that 

 Para is exceptionally rich in wild oil plants. 



Carapa procera (^C guyanensis) ("andiroba") ; its fruit furnishes an 

 oil used in the manufacture of soap, lubrication and lighting oils, but as it 

 contains a bitter principle it is not edible. 



Myristica {Virola) Bicuhyba (" ucuhuba ") furnishes a very thick tallow 

 containing a large proportion of stearin, suitable for the manufacture 

 of soap and candles, and, after purification, for food. 



Astrocaryum vulgare {" tucuma ") yields products similar to those of 

 Elaeis guineensis, namely a pericarp oil (" oleo de palma ") and a kernel 

 oil (" oleo de palmito "),but its fruits are 10 times bigger than those of the 

 oil palm. — Astrocaryum Jawary (" jawary ") also 3d elds a pericarp oil and 

 a kernel oil. On the other hand, A. Mumhaca (" mumbaca "), A. peru- 

 vianum (" huycungu "), and A. rostraium only furnish an oil extracted from 

 the kernel. 



Badris major (" maraja assti "), B. minor (" maraja ") and B. gocno- 

 moides {" marajary ") have an oily kernel. 



Oenocarpus distichus {" bacaba "), 0. minor {" bacobinha "), 0. mul- 

 ticaidis (" ciambo "), 0. Batana (" patana ") and Oenocarpus sp. n. (" ba- 

 cabao ") have seeds which yield a very fine edible oil much superior to that 

 of cotton seeds, but in small quantity only. 



Many species of Altai ea produce kernels which give very high percent- 

 ages of an edible oil, very sweet, resembling that of the coconut. 



Cocos Inajai (= C. eqitatorialis) (" jarena ") and C. Syagrus {" poro- 

 rema ") supply an oil almost equal to that of C. imcifera. 



Pentaclethra fdamcntosa (" pracaehy ") furnishes an edible oil in 

 abundance. 



Pachira aquatica {" mamorana ") yields a highly aromatic and 

 edible fat. 



Erisma calcaratnui (" caranuini " or " jaboty ") supplies a very thick 

 fatty substance. 



Lippia {Platonia) i)isignis (" bacury ") yields a somewhat resinous 

 fatty substance. 



Bcrtholleiia nobilis {—B. excclsa) ("castanha do Para") and Lecythis 

 usitata (" sapucaia ") produce an oil very similar to that of sweet almonds. 



Dipteryx odorafa {" cumarii ") sup])lies a very delicate aromatic oil in 

 abundance.
