of Maize is, according to Roulin, very common in Colombia, and the use of it is 

 attended with a shed(hng of the hair, and even the teeth, of Ijoth man and l)east. 

 Mules fed on it lose their hoofs, and fowls lay eggs without shell. Its action upon the 

 uterus is as powerful as that of Rye ergot, or perhaps more so. The country name of 

 the Maize thus affected is Mais peladero. This statement however requires con- 

 firmation.

soil is sandy or chalky in character. AVhen its form is somewhat long, and it is of a very dark colour, 

 or if it has been gathered in plains or damp valleys, it is of inferior quality. On chemical analysis, 

 according to the experiments of Vauquelin, Wiggers, and others, it yields nearly half its weight in oil, 

 resin, wax. fatty matter and gum, all hydrogenous principles, and a little all)umen, and nitrogenous 

 extract. If the season has been a wet one, or if the Ergot has been gathered in moist places, these 

 principles lose their relative proportions ; and the spurred Rye, approaching nearer in quality to good 

 grain, contains but few oleo-resinous principles. It is worthy of remark, that this parasitic grain is 

 only met with on the finest plants of Rye in shady places, or towards the ends of fields recently cleared 

 of wood, and where the carbonic principles and a rich soil abound. — Chemical Gazette.
