Observations on this Case. 



1. The marked symptoms in this case, with the duration 

 of the disease, and the sudden return of vision so quickly 

 after inhaling a superoxygenated air, is a strong proof of the 

 efficacy of the means employed. 



2. These fits, with the blindness, arose from the gradual 

 deposition of water in the brain. 



3. The absorption was occasioned by the powerful action 

 of the v:r:I air on the absorbents, aided by other tonic me- 

 dicines. 



4. Under the other usual practices, this disease commonly 

 terminates in death ; and even when cured bv oxygenated 

 mercury leaves the constitution so enfeebled, that the patient 

 60on after falls a victim to some other disease. 



I remain, dear Sir, 



Your's trulv, 

 Robert John Thornton.
