On Intestinal Rest and Movement. 



219 



It is thus that during a fasting condition, the sound being unrestrained, 

 the first part of the fistulous intestine is traversed rapidly ; but that 

 afterwards a marked diminution in speed occurs, whilst with a smaller 

 sound moving freely, or a larger sound restrained for a time, the rapid 

 initial peristalsis would not be observed. 



In illustration of this point I give the notes of an experiment. 



Experiment III, Chart II. Experiment VI, Chart V. 



'Experiment III (Chart II and Curve II).— 0'. Introduced large 

 oblong sound (metal capsule, weight 3"4 grams, 18 mm. long 

 by 9 mm. greatest breadth) into upper fistulous opening. 

 Sound allowed to travel, no traction being made upon it but 

 that occasioned by the weight of the pen (2 grams). 



Experiment III, Curve II. 



Reduced scale = -g^ths.
