In Little Genesee, N. Y., at the residence of his son, J. A. Langworthy, on the 5th inst., Deacon John Langworthy, in the 81st year of his age. Deacon L. made his home habitually in Alfred, but had gone over to Genesee to visit his relatives, and while there died after an illness of only four or five days. He was a worthy man, a consistent Christian, and very highly esteemed by his large circle of friends. He was well known through a large portion of the Seventh-day Baptist denomination, and has always been regarded as one of the most efficient supporters of our cause. His end was peaceful, accompanied with a calm reliance upon Him who died for sinners.
