152 PHYSIOLOGY AT THE FARM. 



while the animal is neither eating nor ruminating, at the mo- 

 ment when a slight movement of the abdomen is perceived the 

 finger in the paunch is sensible of a contraction in it also ; and 

 if the finger is quickly transferred to the honeycomb, food is 

 discovered to be passing from the paunch into the honeycomb. 

 Moreover, if a substance be introduced on the left side of the 

 body of the animal into the paunch by the artificial aperture, 

 this substance, after a certain time, more or less altered, issues 

 by the artificial aperture in the honeycomb on the right side of 

 the animal. Thus not only does the aliment swallowed in the 

 first deglutition pass, some part into the paunch, some part 

 into the honeycomb, but the aliment also passes, with the aid 

 of the contraction of the abdominal muscles, at least from the 

 paunch into the honeycomb, if not also from the honeycomb 

 into the paunch, independently either of deglutition or rumina- 

 tion. 



But to proceed to what happens during the second degluti- 

 tion. When the finger is introduced into the paunch through 

 the artificial opening, during rumination, portions of the rum- 

 inated aliment are discovered at intervals to enter the paunch ; 

 and the same thing is observed with respect to the honeycomb 

 when the finger is transferred thither by the artificial aperture 

 belonging to it ; and when the margins of the aperture into the 

 honeycomb are held aside, a part of the ruminated aliment is 

 seen to take the course of the demi-canal of the gullet, and to 

 pass at once into the mariyplies. Thus, in the second deglu- 

 tition, while rumination is going on, the first and second 

 stomachs do receive a portion of the ruminated aliment, and 

 the rest of it passes at once by the demi-canal into the third 

 stomach. 



It appears to be a mistake to say that, in drinking, the 

 liquid passes at once in totality into the third stomach, and 

 so into the fourth. If there be an artificial aperture in the
