3d. Nitrogen, so essential to animals, which is not absorbed in 

 any other way than by the food received through the digestive 

 organs, exists in the glutinous part of this grain. 



4th. Starch, the matter which so readily undergoes transforma- 

 tions into other carbonaceous ingredients, exists in the corn, and is 

 one of the most nutritive ingredients, capable of being converted into 

 fat, or into any other matter having carbon, hydrogen and oxygen 

 for their elements. 



5th. The oil of corn is ready formed fat, requiring but little 

 change in the animal economy. 



7th. The peroxide of iron of corn, furnishes the red globules of 

 the blood with that important ingredient, the transporter of oxygen, 

 which gives the blood its renovating properties. 



These ingredients, common also to other cereal grains, explain 

 to us why they have been justly called the " staff of life." 



Analysis of the Raspberry Bush : 



Having noticed that the raspberry bush sprung up wherever 

 fields had been burnt over, and also by the side of decomposing 

 stone walls, Dr. J. was led to analyze it, with the expectation of 

 finding an unusual amount of potash. 



The following are the results of the analysis of the Rubus stri- 

 gosus : 1000 grains of the dry raspberry bushes were burnt in a 

 platina dish, in a muffle, and the ashes collected in this manner 

 were found to be burnt perfectly free from carbon. The amount 

 of ashes from 1000 grains of the bushes was 16.2 grains, or 1.62 

 per ct. It was easily melted, and flowed in the capsule. The 

 fused ashes, analyzed in the usual manner, yielded
