PLATE III. 

 Magnified 175 diameters. 



Description of the microscopic structure of the poison 

 gland of tiger snake (Hoplocephalus curtus). 



This is similar to that of a parotid gland. The 

 epithelium of the alveoli is tessellated ; the cells are 

 polyhedral, with comparatively large nuclei ; the nuclei 

 are granular. The coagulated contents of the alveoli 

 consist of ddbris of cells, nuclei, &c. 



The tubules are distinctly lined with columnar epi- 

 thelium, the nuclei being situated near the periphery 

 of the tubule.
