 til the parts are healed over. This may necessitate 

 transplantation from other portions of the globe, or 

 horrow from a rabbit's eye. An adhesion, growing 

 together, of the lid margins, is Anchyloblepharon, com- 

 plete or partial. 



Treatment is division. (See. Fig. 21.) 

 Chalazion is obstruction of some of the follicles 



of the tarsus ■with re- 

 tention of its secretion. 

 The diagnostic point is 

 that the skin is freely 

 movable over it. Vary 

 in size, and are apt to

 Make the primary incision on the skin surface — -parallel 

 to the lid border. May open on the inside if it points 

 that way. This has a sac wall, remember, which must 

 he either removed or thoroughhj scraped, curetted, 

 spooned out. Cocaine will be the only ansesthetio 

 needed, dropping some of a 4 per cent, solution into 

 the conjunctival sac and hypodermically injecting some 

 alongside the tumor, which will render the operation 

 almost painless. May lightly touch with lunar caustic 

 to insure healing. All operations upon the lids are
