The symptoms of this disease are frequent sneezing and shaking of the
head. Some drops of pectoral elixir in the infusion of speedwell, which
the sick birds must be made to take, appears to me to be the most
efficacious remedy. I have given fowls even twenty drops of the elixir
in a glass of the infusion.
When it is merely hoarseness, Dr. Handel, of Mayence, gave to his birds
for several days, as their only drink, a very diluted decoction of dry
figs, sweetened with a little sugar, and afterwards purged them for two
days following, with the juice of carrots.
