Miscellanies. 349 



The arrangement of the Elements, prepared for the classes in 

 Yale College, is as follows : 



Volume I. 



I. Imponderable agents. 



Under this division are included light, heat, and attraction,* and 

 a general outline of galvanism. 



II. Ponderable bodies. 



1. Inorganic bodies. Section 1. Oxygen, as a simple support- 

 erf of combustion. Sec. 2. JVitrogen, and the atmosphere. Sec. 3. 

 Hydrogen and water, and the oxy-hydrogen or compound blow-pipe. 

 Then follow, 



The Alkalies, in the order : 



Sec. 1. Ammonia. 2. Potassa. 3. Soda. 4. Lithia; — with 

 the metallic bases of the three latter. 



The Earths, in the order: 



Sec. 1. Lime. 2. Baryta. 3. Strontia. 4. Magnesia. 5. 

 Silica. 6. Alumina. 7. Zirconia. 8, Glucina. 9. Yttria. 10. 

 Thorina, (added in an Appendix) with their respective bases, and a 

 notice of Glass, after Silica ; and of Porcelain, after Alumina. Next 

 come. 



The Simple Inflammables, in the order : 



Sec. 1. Hydrogen, (as it was before described, it is only niention- 

 ed here, in its natural order.) 



Sec. 2. Sulphur — its acids and salts ; sulphurets, hydrosulphu- 

 rets, he. 



Sec. 3. Carbon — carbonic acid, carbonates, carbonic oxide, car- 

 bufetted hydrogen, &:c. 



Sec. 4. Phosphorus — its acids and salts ; compounds, with com- 

 bustibles and bases, he. 



Sec. 5. JVitrogen, (not a combustible in the popular sense, but 

 sustaining relations to oxygen similar to those of combustible bodies) 

 — acids of nitrogen, oxides, salts, &c. 



* We know not what attraction is ; it is certainly an agent, and we cannot prove 

 that it is material, much less ponderable ; it stands therefore, correctly, under this 

 head. t Not supporters, as misprinted in the work.
