TECHNIQUE OF EYE DISSECTIONS 



tached to the processus zonuloe. This pigment 

 may be easily removed by scraping it off 

 with the sharp edge of the scalpel or by 

 brushing it off with a soft, wet tooth-brush. 



It is unwise to use alcohol as a preservative 

 because it produces an almost immediate 

 opaqueness and hardness which spoils the 

 specimen for further study. 



This description may give the impression 

 that the dissection is a lengthy one; however, 

 it can be done by an expert in two or three 

 minutes; by a beginner in five or six minutes. 



For purposes of demonstration or study the 

 specimen should be placed in a small bottle or 

 a vial containing a 5 per cent, solution of 

 formaldehyde. It can then be examined with 

 hand lens or microscope. (Fig. 7.)
