Medici, in his panegyric of Galvani, which we shall have occasion to quote from more than once, gives a very pretty story of the doctor's wooing and marriage with Lucia Galeazzi, which we prefer to repeat in the naive simplicity with which it is related by the Italian panegyrist.
Galvani had been seriously thinking of matrimony for some time and had, it seems (strange as that might be considered in a rising young scientist in our day), even prayed for counsel in the matter. One of his favorite saints was St. Francis of Sales, the Archbishop of Geneva, the gentleman saint as he has been called, for whose charming personal character Galvani had a very devout admiration. One day while praying in one of the churches of Bologna before a statue of St. Francis of Sales he looked up after some moments of abstraction to find a young woman's face between him and the altar. The face proved to be that of Lucia. Galvani looked upon it as a sign from heaven of approval of some of his wishes, and applied for the hand of the fair Lucia. Anyone who has seen the offerings at the shrine of St. Anthony of Padua, not so far from Bologna, and has realized that the good patron of things lost seems also to be a special subject of recourse in cases of lost hearts among the northern Italians even at the present day, will realize that probably the story as told is the simple truth without any tincture of romance.
Galvani began original work of a high order very early in his medical career. His graduation thesis with regard to bones, treating specially their formation and development, attracted no little attention and is especially noteworthy because of the breadth of view in it, for it touches on the various questions relative to bones from the standpoint of physics and chemistry as well as medicine and surgery. It was sufficient to obtain for its author the place of lecturer in anatomy in the University of Bologna, besides the post of director of the teaching of anatomy in the Institute of Sciences, a subsidiary institution. From the very beginning his course was popular. Galvani was an easy, interesting talker, and he was one of the first who introduced experimental demonstrations into his lectures.
At this time the science of comparative anatomy was just beginning to attract widespread attention. John Hunter in London was doing a great work in this line which has placed him in the front rank of contributors to biology and collectors of important facts in all the sciences allied to anatomy and physiology. Galvani took up this work with enthusiasm and began the study particularly of birds. These animals, the farthest removed from man of the beings that have warm blood, present by that very fact many interesting contrasts and analogies, which furnish important suggestions for the explanation of difficult problems in human anatomy and physiology.
His experimental work in comparative anatomy, strange as it might appear and apparently not to be expected, led him into the domain of electricity through the observation of certain phenomena of animal electricity and the effect of electrical current on animals.
Like so many other great discoveries in science, his first and most important observations in electrical phenomena [{119}] were results of an accident. Of course, it is easy to talk of accidents in these cases. The fall of the apple for Newton, Laennec's observation of the little boys tapping on a log in the courtyard of the Louvre, from which he got his idea for the invention of the stethoscope, were apparently merest accidents. Without the inventive scientific genius ready to take advantage of them, however, these accidents would not have been raised to the higher planes of important incidents in history. They would have meant nothing. The phenomena had probably occurred under men's eyes hundreds of times before, but there was no great mind ready to receive the seeds of thought it suggested and go on to follow out the conclusions so obviously indicated. Galvani's observation of the twitching of the muscles of the frog under the influence of electricity may be called one of the happy accidents of scientific development, but it was Galvani's own genius that made the accident happy.
There are two stories told as to the method of the first observation in this matter. Both of them make his wife an important factor in the discovery. According to the more popular form of the history, Galvani was engaged in preparing some frog's legs as a special dainty for his wife, who was ill and who liked this delicacy very much. He thought so much of her that he was doing this himself in the hope that she would be thus more readily tempted to eat them. While so engaged he exposed the large nerve of the animals' hind legs and at the same time split the skin covering the muscles. In doing this he touched the nerve-muscle preparation, as this has come to be called, with the scalpel and little forceps simultaneously, with the result that twitchings occurred. While seeking for the cause of these twitchings the idea of animal electricity came to him.
The other form of the story of his original discovery is not [{120}] less interesting and is perhaps a little more authentic. One evening he was engaged in his laboratory in making some experiments while some friends and his wife were present. By chance some frogs, the hind legs of which had been stripped of skin, were placed upon the table not far from an apparatus for the generation of frictional electricity. They were not in contact with this apparatus at any point, however, though they were not far distant from the conductor. While the apparatus was being used to produce a series of sparks, a laboratory assistant, without thinking of any possible results, touched with the point of a scalpel the sciatic nerves of one of the animals. Just as soon as he did this all the muscles of this limb went into convulsive movement. It was Galvani's wife who noticed what had happened and who had the assistant use the scalpel once more with the same result.
She was herself a woman of well-developed intellect, and her association with her father and husband made her well acquainted with the anatomy and physiology of the day. She realized that what had occurred was quite out of the ordinary. Accordingly, she called the attention of her husband to the phenomena, and is even said to have suggested their possible connection with the presence and action of the electric apparatus. Husband and wife then together, by means of a series of observations, determined that whenever the apparatus was not in use the phenomenon of the conclusive movements of the frog's legs did not take place, notwithstanding irritation by the scalpel. Whenever the electric apparatus was working, however, then the phenomenon in question always took place. According to either form of the story it is clear that Madame Galvani had an important part in the discovery, and Galvani himself, far from making little of what she had accomplished, was always [{121}] glad to attribute his discovery, or at least the suggestive hint that led up to it, to his wife.
