Arthur Thomas Myers, Dictionary of National Biography… (1889)
“ Esdaile felt the imprudence of a hasty adoption of chloroform under all circumstances, inasmuch as there could be little doubt that occasionally its dangers were greater than those of mesmerism, and in India its results might be only a little more certain. He stayed on in Calcutta for three more years, neglecting his opportunities for making a large private practice, though he was still further promoted to be marine surgeon in 1850. His interest in mesmerism continued to be very keen. ”
