" oxy-earbureted light," which has been success- fully used for lighting mines and large public places.

DUNBAR, Moses, soldier, b. in Plymouth, Conn.; d. in Hartford, Conn., 19 March, 1777. He was a resident of Bristol (or, as some say, of Water- Ijury), and was convicted by the superior court in January, 1777, of holding a captain's commission under Sir William Howe, and of enlisting men for the British army. While under sentence of death he knocked down the sentries and escaped, but was apprehended, and on the day appointed, after listen- ing to a sermon at the jail, from Rev. Abraham Jarvis, of Middletown, was hanged in presence of " a prodigious concourse of people." It is charged by Thomas Jones, in his " History of New York," that there was no existing law in the colony mak- ing Dunbar's offence punishable with death, and that he was condemned under an ex-post-facto law. His young wife is said to have been treated inhumanly, being compelled to ride in the cart with her husband to his execution, and afterward expelled from Middletown, where she had taken refuge in a loyalist family. Four exj)resses were sent to Howe by Dunbar's friends urging him to stop the execution by threatening retaliation, but he was inditferent to their appeals.

After the defeat of 9 July, Dunbar destroyed his remain- ing artillery, burned stores and baggage worth £100,000, pretending that it was done by Braddock's orders, and ignominiously retreated. Dunbar was made lieutenant-governor of Gibraltar in 1756, and promoted to lieutenant-general, 18 Dec, 1760.

He held important trusts under the Federal government, was a correspondent of Thomas Jefferson, Herschel, and Rittenhouse, and contributed numerous valu- able papers to the transactions of the American philosophical society of Philadelphia, of which he was a member.
