When that night arrived, Mrs. Magruder pretended to have the "sewing circle" from the church in the parlor, while her husband went to sleep in the sitting-room with that vigilant relative of his on guard. About nine o'clock Mr. Magruder's brother was surprised to observe Mrs. Magruder softly stealing up stairs, with the members of the "sewing circle" following her noiselessly in single file. In her hand Mrs. Magruder carried a volume. If her brother-in-law had conceived the idea that the book might contain the tender strains of some sweet singer amid whose glowing imagery this woman reveled with the ecstasy of a sensitive nature, he would have been mistaken, for the work was entitled "Thompson on the Nervous System;" while those lines traced in a delicate female hand, upon the perfumed note-paper, and carried by Mrs. Magruder, so far from embodying an expression of the gentlest and most sacred emotions of her bosom, were merely a diagnosis of an aggravated case of fatty degeneration of the heart. [Illustration] I give the story literally as I received it from that eminent practitioner Jones. When the whole party had entered the room, Mrs. Magruder closed the door and applied chloroform to her husband's nose. As soon as he became completely insensible, the sewing in the hands of the ladies was quickly laid aside, and to Magruder's secreted brother was disclosed the alarming fact that this was a class of students from the college. If Dr. Jones is to be believed, Professor Magruder began her lecture with some very able remarks upon the nervous system; and in order to demonstrate her meaning more plainly, she attached a galvanic battery to her husband's toes, so that she might make him wriggle before the class. And he did wriggle. Mrs. Magruder gave him a dozen or two shocks and poked him with a ruler to make him jump around, while the students stood in a semi-circle, with note-books in their hands, and exclaimed, "How very interesting!" Magruder's brother thought it awful, but he was afraid to come out when he reflected that they might want _two_ skeletons at the college. Mrs. Magruder then said that she would pursue this branch of the investigation no further at that moment, because Mr. Magruder's system was somewhat debilitated in consequence of an overdose of chlorate of potash which she had administered in his coffee upon the previous day for the purpose of testing the strength of the drug. Mrs. Magruder then proceeded to "quiz" the class concerning the general construction of her husband. She said, for instance, that she had won what was called the heart of Mr. Magruder, and she asked the students what it was that she had really won. "Why, the cardia, of course," said the class; "it is an azygous muscle of an irregular pyramid shape, situated obliquely and a little to the left side of the chest, and it rests on the diaphragm." One fair young thing said that it didn't rest on the diaphragm.
