agent in affecting the deterioration and decomposition of the other parts of 

 the egg with which it may be brought in contact. 



If, during the process of desiccation, the material to be desiccated is al- 

 lowed to rise in temperature above a certain j)oint, hereinafter indicated, 

 the oil of the egg contained in the more solid parts, or which is not in sus- 

 pension or emulsion, but is in more perfect combination with the other con- 

 stituents of the Qgg, particularly that in the yelk, and so in the batter com- 

 posed in the yelks and whites, is set free to a greater or less extent, accord- 

 ing to the freshness and vitality of the eggs used and the degree of such 

 heat. It has also been ascertained, by experiment, that the temperature at 

 which this result follows varies at different times. The causes apparently 

 depend upon barometric and other conditions of the atmosphere as well as 

 the state of the thermometer. Such a result has usually followed whenever 

 the material has been raised above 85° Fah. The highest temperature to 

 which Mr. W. 0. Stoddard, of New York city, who has made a special study 

 of this subject, has been able to subject the material without that result fol- 

 lowing was 92° Fall.; but that was under exceptional atmospheric condi- 

 tions,- and he considers a much lower temperature than 85°, and, if possible, 

 than 80°, very desirable for safety, and essential to commercial success in 

 the manufacture. Indeed, his own operations have been conducted at a 

 temperature not to exceed 80°. 



Mr. Stoddard has lately jDatented (May 8, 1877) a device, the object of 

 which is to regulate and control the temperature of the eggs, or parts of 

 eggs, or batter of eggs, or other material during the process of desiccation, 

 so as to prevent the development or freeing from the more solid part of 

 such material of the oil of the Qgg not held in suspension or emulsion, be- 

 ing much the larger part of all the oil contained in the Qgg^ and afterward 

 to eliminate from the product derived such small portions of the oil of the 

 Qgg as may have been held in suspension or emulsion, or may have been 

 set free in the process of manufacture. The granulated or mealy product 

 which is thus obtained will then, he claims, retain and protect its proper pro- 

 portion of the oil of the Qgg, even if exposed to a much higher temperature 

 than that above mentioned. 



To obtain the object thus substantially set forth while employing for the 

 process of desiccation a dr3^ing blast of warm air, he employs for the rota- 

 ting surface, on which such desiccation is produced, a hollow cylinder, cone, 

 frustrum of a cone, or other surtace which may be artificially cooled by 

 means of ventilation or evaporation in the interior while the material with- 

 in is actively agitated. — Scientific Americaji. 



LIGHT-EMITTING FLOWERS. 



The power of emitting light has been found to be possessed .by several 

 flowers. The daua^hter of the great Swedish naturalist, Llnnffius, was wont
