"To nitrous oxide, chloroform gives way": Was Dr. W.J.A. DeLancey's poetic license in advertising…inspired?

Born in New Hampshire but raised in Massachusetts, 14-year-old William J.A. DeLancey became "the man of the house" after the accidental death of his father. Amiable and good humored, young DeLancey supported his widowed mother and his three sisters until the girls all reached maturity. After he married, DeLancey moved to Illinois and took up dentistry, eventually settling in Centralia. Following anesthesia training back east at Manhattan's Colton Dental Association, DeLancey returned to Centralia. There he practiced the Coltonian method of testing freshly made nitrous oxide upon himself before using the gas upon patients. Before his training at Colton Dental, DeLancey had advertised in Centralia newspapers only in prose. After he began administering laughing gas to his patients and to himself, DeLancey waxed poetic and began advertising in heroic couplets in local newspapers.
