102 CALORIMETERS FOR STUDYING RESPIRATORY EXCHANGE, ETC. 



A most excellent preservation of the record of the minor muscular move- 

 ments is obtained by dipping the smoked paper on the kymograph drum in 

 a solution of resin and alcohol. The lesser movements on the paper indi- 

 cate the respiration rate, but every minor muscular movement, such as 

 moving the arm or shifting the body in any way, is shown by a large deflec- 

 tion of the pointer out of the regular zone of vibration. These records of 

 the minor muscular activity are of great importance in interpreting the 

 results of the chemical and physical determinations.
