Although, in the two recorded cases, the disease existed in the lower part of the oesophagus, it is very proi)abIe that it also occurs in the mouth of birds, a location favorable for its development with most species of animals. The disease does not appear to be very common, although it might be quite frequent and still not be recognized, as but comi^aratively few investi- gators have given systematic attention to poultry dis- eases. Thrush can be distinguished from other dis- eases causing a similar deposit only bj' a microscopic examination. The mj-celium and spores of the fungus
