we make, but through it we derive much of our knowledge of the 

 external world. Through it we are also conscious of the varying 

 condition of the several parts of our body even when the muscles 

 are at rest ; the tired and especially the paralysed limb is said to 

 ' feel heavy.' In this way the state of our muscles and other 

 tissues largely determines our general feeling of health ~arrd 

 vigour, of weariness, ill health and feebleness. 



The fact that the Pacinian bodies are found around joints has 

 led to the suggestion that these serve as the terminal organs of 

 the muscular sense ; but especially bearing in mind what has just 

 been said, the argument which we used against considering the 

 touch corpuscles as the terminal organs of touch may, with 

 perhaps still greater force be applied against regarding the 

 Pacinian bodies as the terminal organs of the muscular sense.
