The temperature of venous blood is higher than that of arterial blood, and 

 its energy is of a negative character, consequently, by law of opposite attrac- 

 tions, its energy and heat are drawn toward the new field of action caused 

 by the molecular rean-angement of elements taking place in the lungs outside 

 the blood stream. It must be kept in mind that heat is a form of electro- 

 chemic energy, and the cooling, watery vapors of the lungs are a good con- 

 ductor for it. 



Draper, in "Medical Physics," page 234, says: "Chemical affinity, heat, 

 motion, magnetism, electricity and light are convertible one into another." 

 Massey, in his "Conservative Gynecology and Electro-Therapeutics," in a 

 foot-note on page 39, says: "Chemic affinity is now understood to be identical 

 with electric affinity." 



The negative oxygen elements of inspired air meet the positive carbon ele- 

 ments which are excreted by the lungs from venous blood. Through the 

 influence of heat molecular rearrangement ensues, and by the nature of the 

 elements rearranged positive electro-chemic energy results. 



It is a fundamental law of chemistry that molecular rearrangement, with 

 chemical union, always produces electro-chemic energy. By the action of 

 opposite attractions, and by the conductivity of oxygen elements the positive 

 energy of the new field is drawn to the negative blood. 



" Venous blood is distributed to the lungs by the pulmonary artery, whose 

 terminal branches form a plexus of capilliary vessels surrounding the air-cells. 

 The air and blood are thus brought into intimate relationship being separated 

 only by the delicate wall of the capillary. A capillary frequently passes 

 through an aperture in the cell wall but never becomes altogether free fr-om 

 it, and no blood escapes into the air-sac during its passage." — Gray's Anatomy. 



In the extremity of the bronchiac we also find non-insulation in the air-sac, 

 showing that Nature has prepared the way for the transmission of electro- 

 chemic energy. 



In Gray's Anatomy," it is said: "The mucous membrane of the trachea and 

 bronchial tubes is pierced by many excretory glands; it is also covered with 

 columnar epithelium." This epithelium acts as a complete insulation to the 

 escape of any electric energy produced within the tubes; but the terminal 

 bronchial tubes lose their epithelium and muscular coat at about one-eighth 

 of an inch from the most distant air-cells to which they may lead, and are 

 thus reduced to a single basement membrane. Thus it also becomes non- 

 insulated to facilitate the transmission of energy to the blood. 



Residual air of the lungs, with the saline, watery elements, plays an impor- 

 tant part in the conduction of electro-chemic energy to and from the blood. 

 Residual air being heavier than tidal air, is drawn back and forth to and from 

 the air-sac, transmitting the energy to and from the blood with perfect, ryth- 

 mic action, similar to the action of a to and fro current. Residual air of the
