"Let us go back to the death of Doctor-Professor Fontaine, at his apartments in the University of Wurzburg, on the 3rd of September, in the present year 1828.
"The poor man died of typhoid fever, as you know--and died in debt, through no extravagance on his own part, as you also know. He had outlived all his own relatives, and had no pecuniary hopes or expectations from anyone. Under these circumstances, he could only leave the written expression of his last wishes, in place of a will.
"This document committed his widow and child to the care of his widow's relations, in terms of respectful entreaty. Speaking next of himself, he directed that he should be buried with the strictest economy, so that he might cost the University as little as possible. Thirdly, and lastly, he appointed one of his brother professors to act as his sole executor, in disposing of those contents of his laboratory which were his own property at the time of his death.
"The written instructions to his executor are of such serious importance that I feel it my duty to copy them for you, word for word.
"Thus they begin:--
" 'I hereby appoint my dear old friend and colleague, Professor Stein--now absent for a while at Munich, on University business--to act as my sole representative in the disposal of the contents of my laboratory, after my death. The various objects used in my chemical investigations, which are my own private property, will be all found arranged on the long deal table that stands between the two windows. They are to be offered for sale to my successor, in the first instance. If he declines to purchase them, they can then be sent to Munich, to be sold separately by the manufacturer, as occasion may offer. The furniture of the laboratory, both movable and stationary, belongs entirely to the University, excepting the contents of an iron safe built into the south wall of the room. As to these, which are my own sole property, I seriously enjoin my executor and representative to follow my instructions to the letter:--
" '(1) Professor Stein will take care to be accompanied by a competent witness, when he opens the safe in the wall.
" '(2) The witness will take down in writing, from the dictation of Professor Stein, an exact list of the contents of the safe. These are:--Bottles containing drugs, tin cases containing powders, and a small medicine-chest, having six compartments, each occupied by a labeled bottle, holding a liquid preparation.
" '(3) The written list being complete, I desire Professor Stein to empty every one of the bottles and cases, including the bottles in the medicine-chest, into the laboratory sink, with his own hands. He is also to be especially careful to destroy the labels on the bottles in the medicine-chest. These things done, he will sign the list, stating that the work of destruction is accomplished; and the witness present will add his signature. The document, thus attested, is to be placed in the care of the Secretary to the University.
" 'My object in leaving these instructions is simply to prevent the dangerous results which might follow any meddling with my chemical preparations, after my death.
" 'In almost every instance, these preparations are of a poisonous nature. Having made this statement, let me add, in justice to myself, that the sole motive for my investigations has been the good of my fellow-creatures.
" 'I have been anxious, in the first place, to enlarge the list of curative medicines having poison for one of their ingredients. I have attempted, in the second place, to discover antidotes to the deadly action of those poisons, which (in cases of crime or accident) might be the means of saving life.
" 'If I had been spared for a few years longer, I should so far have completed my labors as to have ventured on leaving them to be introduced to the medical profession by my successor. As it is--excepting one instance, in which I ran the risk, and was happily enabled to preserve the life of a poisoned man--I have not had time so completely to verify my theories, by practical experiment, as to justify me in revealing my discoveries to the scientific world for the benefit of mankind.
" 'Under these circumstances, I am resigned to the sacrifice of my ambition--I only desire to do no harm. If any of my preparations, and more particularly those in the medicine-chest, fell into ignorant or wicked hands, I tremble when I think of the consequences which might follow. My one regret is, that I have not strength enough to rise from my bed, and do the good work of destruction myself. My friend and executor will take my place.
" 'The key of the laboratory door, and the key of the safe, will be secured this day in the presence of my medical attendant, in a small wooden box. The box will be sealed (before the same witness) with my own seal. I shall keep it under my pillow, to give it myself to Professor Stein, if I live until he returns from Munich.
" 'If I die while my executor is still absent, my beloved wife is the one person in the world whom I can implicitly trust to take charge of the sealed box. She will give it to Professor Stein, immediately on his return to Wurzburg; together with these instructions, which will be placed in the box along with the keys.'
"There are the instructions, friend Fritz! They are no secret now. The Professor has felt it his duty to make them public in a court of law, in consequence of the events which followed Doctor Fontaine's death. You are interested in those events, and you shall be made acquainted with them before I close my letter.
"Professor Stein returned from Munich too late to receive the box from the hands of his friend and colleague. It was presented to him by the Widow Fontaine, in accordance with her late husband's wishes.
"The Professor broke the seal. Having read his Instructions, he followed them to the letter, the same day.
"Accompanied by the Secretary to the University, as a witness, he opened the laboratory door. Leaving the sale of the objects on the table to be provided for at a later date, he proceeded at once to take the list of the bottles and cases, whose contents he was bound to destroy. On opening the safe, these objects were found as the Instructions led him to anticipate: the dust lying thick on them vouched for their having been left undisturbed. The list being completed, the contents of the bottles and cases were thereupon thrown away by the Professor's own hand.
"On looking next, however, for the medicine-chest, no such thing was to be discovered in the safe. The laboratory was searched from end to end, on the chance that some mistake had been made. Still no medicine-chest was to be found.
"Upon this the Widow Fontaine was questioned. Did she know what had become of the medicine-chest? She was not even aware that such a thing existed. Had she been careful to keep the sealed box so safely that no other person could get at it? Certainly! She had kept it locked in one of her drawers, and the key in her pocket.
"The lock of the drawer, and the locks of the laboratory door and the safe, were examined.
