of the lower portion of the wound, then thrust through 

 the upper border of the tarsus and the tarso-orbital 

 fascia, as well as the skin at the upper portion. The 

 lateral needles are placed in the same manner. A good 

 needle-holder should be used in this operation, as well 

 as in all operations on the lids (Fig. 18).

Electrolysis is used with success in some cases to

 of hair. As soon as the contact is made a whitish foam 

 will appear about the entrance of the needle. The sponge
