said to prevent apoplexy and palsy. The danger 
of suppressing an artificial drain from the nose by 
habitual use of snuffin apoplectic habits discussed. - 
I}lustrations given. Boyles report of absorption 
ef cataract by euphorbium, a powerful errhine, 
stated. The efficacy of these remedies in opthal- 
mia, stated. Sneezing as a critical occurrence in 
fevers and hydrocephalus, noticed; said to be 
favourable. This effect occurred in ten thousand 
men of Xenophon’s army on the Euxine sea, on

used by Loesecke in gutta serena with efficacy. 
The medicines just mentioned, with the vapour of 
spirit of sal-ammoniac, white hellebore, marjo- 
ram, lavender, orris-root, horse-chesnut, hedera 
terrestris and betony, are the chief subjects of this 
class. We have several indigenous plants which 
possess the same errhine property, as helenium, 
autumnale or sneeze-weed, sanguinaria canadensis, 
&c. Warm water snuffed up the nose acts as an 
errhine. The juice of common beet applied in the 
‘same way is slightly errhine. The-snufting of
