So.— (28a) This is a sheet of plate glass 4 by 4 feet, bespattered with venom spat by a Black 

 Ringhals. For a week or two after capture, it sent a shower of venom at every visitor. There is 

 enough venom on glass to kill 100 men. (28B) The appearance of glass when free from venom. 

 Note how transparent it is. The accumulation of venom on glass in top picture is so great that, 

 although several snakes are on the stump of a tree behind, nothing can be seen of them. When 

 actually looking at the glass, the contents can be dimly discerned. This snake cage was in the 

 old Port Elizabeth Museum.
