DEATH OF JOHN JONES, ESQ. - The sudden death on MONDAY, of Mr. Jones, has been a great shock to the religious community of which he had long been an exemplary and active member, as well as to the large circle in which he was well known and esteemed. During last summer, Mr. Jones consulted Mr. Edmund Smith, of Norfolk street, one of the most eminent homeopathic practitioners in the country, and at that time Mr. Smith warned him that he was suffering from a disease of the heart. It appears, that on Monday, Mr. Jones was at his shop, in the Market place, and after writing a letter, about three in the afternoon, felt so ill, that he was but just able to go into the next room, where he sank upon a sofa. Mr. Radley, the chemist, was called in, and administered some stimulants. About half-past three, Mr. Smith arrived. Mr. Jones was then seated in a chair. Mr. Smith found that the right lower limb was paralysed, and recommended the removal of Mr. Jones to his house. Before this was done, Mr. J. Jones, Jun., introduced Dr. Kidley, who, after a careful examination of the symptoms, finding Mr. Jones in the care of his ordinary medical attendant, did not interfere, though he concurred with Mr. Smith in the opinion that the system had received a great shock, and that the object must be to arouse and support the vital powers. Mr. Jones bore the removal home well, and was put to bed, but the stroke of death was visible in his countenance, though his intellect continued perfectly calm and clear. External and internal stimulants were administered, suitable to check an attack of diarrhoea, which was one of the symptoms. This was accomplished, and the bowels remained in a quiet state from nine o'clock till twelve. In the course of the evening, however, Mr. Smith mentioned to the family his apprehension that internal bleeding was going on from one of the vessels of the heart, or of the spine. About twelve o'clock, another disturbance of the bowels took place. The pulse was then very slow and feeble, and the face, which had been cold and sunk, was still more so. Mr. Jones at this time spoke a few words as to the dangerous nature of the attack, but expressed his resignation, and conviction that all had been done for the best. A moment later, a deep inspiration, the cessation of the pulse, and two or three sobs, announced the termination of the struggle. The same night, Mr. Smith informed Dr. Kindley of the result, and requested that he would apply to Mr. Wm. Jackson, the senior medical practitioner in Sheffield, to make a post mortem examination of the body. This was done on the following day, by Messrs. Jackson and Son, in the presence of Dr. Kindlry and Mr. Smith. the cause of death was most distinctly traced to aneurism of the aorta, at a point remarkably near the heart. The disease was of long standing. The elastic coat of the artery had been absorbed, and there remained only the membranous sheath. This had at length given way, and the pericardium of the heart was found to be full of blood. The surprise of the medical gentlemen, when the state of things was disclosed, was not at the fatal result, but that Mr. Jones should have lived at all after the attack. The following is the conjecture by which it is accounted for :- The accelerated flow of blood, caused by some mental emotion, produced a very small rupture of the diseased blood vessel, and hence the first attack. But an interval of quietness may have allowed a coagulation of blood to have been formed over the rupture, and so retarded the bleeding. The disturbance of the bowels from time to time, would increase the evil. When the last disturbance took place, it is supposed to have extended the rupture, (which was found to be an inch in length) and a sudden rush of blood into the pericardium then proved immediately fatal. The friends of the deceased derive the melancholy satisfaction of knowing that no human help could have been of any avail.
