No matter, the compliment touched his heart. He resumed the letter:
"At three this morning we exhumed poor Sauvresy's body. I certainly deplore the frightful circumstances of this worthy man's death as much as anyone; but on the other hand, I cannot help rejoicing at this excellent opportunity to test the efficacy of my sensitive paper—"
"Confound these men of science," cried the indignant Plantat. "They are all alike!"
"Why so? I can very well comprehend the doctor's involuntary sensations.
Am I not ravished when I encounter a fine crime?"
And without waiting for his guest's reply, he continued reading the letter:
"The experiments promised to be all the more conclusive as aconitine is one of those drugs which conceal themselves most obstinately from analysis. I proceed thus: After heating the suspected substances in twice their weight of alcohol, I drop the liquid gently into a vase with edges a little elevated, at the bottom of which is a piece of paper on which I have placed my tests. If my paper retains its color, there is no poison; if it changes, the poison is there. In this case my paper was of a light yellow color, and if we were not mistaken, it ought either to become covered with brown spots, or completely brown. I explained this experiment beforehand to the judge of instruction and the experts who were assisting me. Ah, my friend, what a success I had! When the first drops of alcohol fell, the paper at once became a dark brown; your suspicions are thus proved to be quite correct. The substances which I submitted to the test were liberally saturated with aconitine. I never obtained more decisive results in my laboratory. I expect that my conclusions will be disputed in court; but I have means of verifying them, so that I shall surely confound all the chemists who oppose me. I think, my dear friend, that you will not be indifferent to the satisfaction I feel—"
M. Plantat lost patience.
"This is unheard-of!" cried he. "Incredible! Would you say, now, that this poison which he found in Sauvresy's body was stolen from his own laboratory? Why, that body is nothing more to him than 'suspected matter!' And he already imagines himself discussing the merits of his sensitive paper in court!"
"He has reason to look for antagonists in court."
"And meanwhile he makes his experiments, and analyzes with the coolest blood in the world; he continues his abominable cooking, boiling and filtering, and preparing his arguments—!"
