 ALCOHOL. EXHAUSTION, 76-59 cm. 



' Axial colors very marked. ' Two hours later, small, perfect multiannular coronas are seen.

Axial colors not seen ; coronas very fleeting and not measurable. 

 2 Examined next day, the residual nuclei produced small but fine multiannular coronas. 



The table shows that the remarks already made for alcohol may be repeated here.
