lung sick

As for “lung sick,” which is a dreadful form of pneumonia, very prevalent in this country, they [the oxen] had all been inoculated against it. This is done by cutting a slit in the tail of an ox, and binding in a piece of the diseased lung of an animal which had died of the sickness.

[…] a contagious disease broke out among my cattle; […] . Having shot one, the disease proved to be a contagious pleuro-pneumonia, similar to the ‘lung sick’ so prevalent in this neighborhood, affecting hips and shoulder-blades, causing lameness. […] we were surrounded by ‘lung-sick’ cattle dying near our encampment.

Lung sickness appeared at Toise River about this time. […] I certainly think that if affected animals with lung sick cannot be slaughtered on recovery they should be branded.
