Dr. Jackson made another claim, resting on a more substantial basis, on which both scientific and general opinion have been and probably always will be divided. The question whether he or Dr. W. T. G. Morton was the real discoverer of anasthesia, will never be settled, and perhaps the only solution it will reach is that which gives both jointly the credit of the great discovery. A memorial was presented to Congress in 1852, signed by one hundred and forty-three physicians of Boston and vicinity, ascribing the discovery exclusively to Dr. Jackson. The French Academy of Science decreed a Montyon prize of 2,500 francs to Jackson for the discovery of etherization, and one of the same amount to Morton for the application of the discovery to surgical operations. Dr. Jackson received orders and decorations from the governments of France, Sweden, Prussia, Turkey and Sardinia, but what the final verdict of history, the court of last resort, will be, it is too early to say. Dr. Jackson was a man of broad and deep scientific learning, and in exploring the mysteries lying in the field of science he found so much that his frank and open nature would not permit him to conceal, that those who knew him were not surprised at the disputed claims which marked his career. He knew too much, and too many things for him to develop, and by his own labors to apply to practical use. His mind was like a garden so crowded with vegetation of his own planting that none or few reached perfect bloom and seed. But the passerby attracted by one or another, though ignorant of botany, would pluck a slip or a root, and setting it in his own grounds, by unremitting care nurse it into vigorous growth and a perfected life. Without the garden which the gardener had planted, the passerby would never have found the plant, and without the act of the passerby the plant would have died and the labors of the gardener would have been in vain. Thus it is true that one soweth another reapeth. Dr. Jackson married Susan Bridge of Charlestown, and died in 1880.
