Following that atmospheric disturbance every member of my party, and even some of the Eskimos, had a pronounced attack of grip.

It was our opinion that the germs were brought to us by this storm, which was more than a local disturbance.
Aside from rheumatism and bronchial troubles, the Eskimos are fairly healthy; but the adults are subject to a peculiar nervous affection which they call _piblokto_--a form of hysteria.

I have never known a child to have _piblokto_; but some one among the adult Eskimos would have an attack every day or two, and one day there were five cases.

The immediate cause of this affection is hard to trace, though sometimes it seems to be the result of a brooding over absent or dead relatives, or a fear of the future.

The manifestations of this disorder are somewhat startling.
The patient, usually a woman, begins to scream and tear off and destroy her clothing.
