Holograph, signed.
Edmund Quincy sends a letter from Sydney H. Gay which explains why the imprint of last week's paper [the National Anti-Slavery Standard] remains unchanged. Arrangements should be made to have the Standard carried and delivered to Boston. Edmund Quincy sends a New York Express with "a rather rich account of the [New England] Convention." Edmund Quincy suggests a simple method of producing the tract on the origin of the 3rd party, about which Stephen S. Foster had spoken.
