if they do take place, are owing to the presence of unstriped cutaneous 

 muscles. 



Muller next inquires into the existence of unstriped muscles in the 

 skin of the ear. He has occasionally found, on galvanising the cervical 

 sympathetic in cats, that a movement of the hairs growing upon the 

 skin at the entrance of the concha has taken place. This experiment 

 has, however, frequently failed both in cats and other animals. A 

 careful examination of the skin of the part did not give any indications 

 of unstriped muscles, but very distinct muscles were seen connected to 

 the hair follicles. He considers these experiments of interest, as they 

 appear to indicate whence the muscles of the hair follicles receive their 

 nerves. Owing to the movement of the hairs being limited to a very 

 small locality, during the irritation of the sympathetic, one must suppose 

 that only a very small part of the unstriped muscular apparatus of the 

 skin of the cat can be regulated by the cervical sympathetic.
