sing circumstances of their incarceration, and the influence of the 

 unhealthy season of the year, quickly showed itself, and three months 

 after became more evident, when they found the chance of liberty 

 and reward more distant and uncertain. 



At this time nearly all the above prisoners became more or less 

 affected with Hemeralopia ; many of them could not see clearly 

 during the day, and as soon as the sun set and light diminished, they 

 became completely blind until the bright sun of the next morning 

 stimulated sufficiently the retina to action. The light of candles 

 and of the moon, was insufficient to enable them to see. Their 

 pupils were dilated, the retina pallid, and the iris sluggish. In all 

 these cases a generous diet with aperients and tonics quickly restored 

 their vision, and an improved scale of allowance quickly stopped the 

 disease in the jail. Dysentery appeared, with hot skin, quick pulse, 

 and white tongue, followed by cedematous swellings of the extremities, 

 and great debility. Their ears became painful and discharged pus. 

 The conjunctiva next became of a pinkish redness, especially round 

 the cornea ; and the eye became very painful, and sensible to light. 

 The cornea was dull and irregular in its surface, followed by ulcera- 

 tion round its edge. (See specific inflammation of the globe of the 

 eye.) These changed to a yellowish and pulpy slough. The com- 

 plications in some of these cases of hemeralopia were as follows :
