a spoon; if in a small jar or vial, empty out 

 the fluid, then slide the specimen out on what-

 suspensory ligament in the Zone of Zinn. In- 

 sert the pointed end of the glass tube, close to 

 the lens, and blow gently until the canal shows 

 its sacculated construction by filling with air, 

 giving the appearance of a lot of little bubbles 

 surrounding the periphery of the lens. (Fig. 

 8.) It may be necessary to move the blow- 

 pipe in and out in order to find the canal, all 

 the while blowing steadily through the tube.
