Dr. Scott's Electric Hair Brush. — A good hair brush cannot be bought for 

 much less than the sum for which Dr. Scott's electric brush can be secured. 

 This brush, aside from the curative properties claimed for it, is a well made arti- 

 cle, handsome in appearance and first-class in every respect. It is not a metallic 

 brush, but is made of pure bristles. Its electrical qualities are very strong, and 

 will manifest themselves by causing the needle of a magnetic compass to vibrate 

 even with a thick book on the top of a table intervening. Violent vibrations of 

 the needle can be caused by passing the brush quickly back and forth within 

 four or five inches of the compass. It is claimed for this brush that its use will 

 cure headaches and neuralgia, will remove dandruff, and in most cases will pre- 

 vent the hair from falling or turning gray. In support of this claim many testi- 

 monials from responsible persons are adduced. Evidently its use would be of 

 great benefit wherever electricity would prove beneficial, and could not in any 

 event result in harm. — Boston Journal, May 28, 1881.
