Treatment of Foreign Bodies in the (Esophagus._ 
A horse had a pill given it which remained, as subsecpient ex¬ 
amination showed, wedged in the oesophagus. The administra¬ 
tion of 0,007 °f arecoline hydrobromicum. caused after 15 
minutes the foreign body’s passage into the stomach. Pilocarpin 
according to J., has a similar action. The author therefore 
recommends the administration of either or both of these 
remedies when occasion offers.— {Berl. Thierarzt. IVoch.) 
Hucain in Ophthaemoeogy. —Eucain is a new anaesthetic 5 
cheaper and less poisonous than cocaine and with less disturbino- 
properties than cocaine. The hydrochlorate of eucain dissolves 
in water, retaining its anaesthetic properties even after boilino- 
but, on the contrary, it is only partly soluble in 2 per cent, sub¬ 
limate solution. V. used it as he did cocaine in 5 per cent, solu¬ 
tion. The instillation of eucain causes much more burnino' 
than cocaine, each new instillation causing fresh smarting. The 
anaesthesia sets in in 2 to 3 minutes in the cornea and conjunc¬ 
tiva, diminishes gradually after 8 to 12' minutes and disappears 
entirely after 15 minutes. The following advantage claimed by 
the firm (Schering), viz., non-dilation of the pupil, absence of 
paresis of the muscles of accommodation, did not materialize to 
any marked extent. With cocaine one had been very lono- 
warned that it might cause unnatural dryness of the corneal 
epithelium owing to the diminution in lid activity caused by 
the cocaine ; eucain does the same to a more marked degree, 
robbing the cornea and conjunctiva of their protective covering 
by paresis of the lids and causing in time a total separation o! 
the corneal epithelium from its base. Even sewing the lids 
together won’t prevent this. Hence eucain can’t supplant co¬ 
caine.— {Berl. Thierarzt. Woch.)
