Spasm as in lock-jaw. Arms flexed at elbows.

Many eye symptoms were noted: steady and extreme oscillation of the eyeballs. Eyes distorted. Lids half closed. Dark bodies moving before eyes. вy open air (vertigo, convulsions). It is a popular custom to take children suffering from whooping-cough to breathe the air at a gas-works.
