1850), was a case in the Massachusetts Supreme Judicial Court that contributed to the "fellow servant rule".

Another employee, the superintendent of the plant, had been grossly negligent in instructing his subordinate, an overseer, who was in charge of the gas lighting.

As a result, gas filled the room in which the plaintiff was working so as to "throw her into spasmodic fits, and occasion her a very serious and lasting injury."

(The overseer was "hired and discharged by the superintendent, usually with the advice of the treasurer ... the overseers of the rooms hired and discharged the operatives employed in their respective rooms ... all these officers and operatives were paid for their services by the paymaster of the defendants, at their counting-room.")

It was admitted that the plaintiff received the injury "through the gross negligence and want of skill of the superintendent, in directing the person employed in the manufacture of the gas, with which the mill was lighted, to throw off all the weights from the gasometer, by means of which the gas was forced into the mill;" and it was admitted "that the management of lighting the mill, and manufacturing gas for the purpose, was a matter under the control of the superintendent."
