Joseph Burner[77] and Anna Maria, his wife, were poor but intelligent persons, who were not merely respected but even looked up to for their probity and industry by their fellow-villagers of Illfurt. The family consisted of five children, the eldest son, Thiébaut, being born on 21 August, 1855, and the second, Joseph, on 29 April, 1857. They were quiet lads of average ability, who, when eight years old, were sent in the usual course to the local elementary school. In the autumn of 1864 both were seized with a mysterious illness which would not yield to the ordinary remedies. Dr. Levy, of Altkirch, who was called in to examine the case acknowledged himself completely baffled, and a number of other doctors who were afterwards consulted declared themselves unable to diagnose such extraordinary symptoms. From 25 September, 1865, the two boys displayed most abnormal phenomena. Whilst lying on their backs they spun suddenly round like whirling tops with the utmost rapidity. Convulsions seized them, twisting and distorting every limb with unparalleled mobility, or again their bodies would for hours together become absolutely rigid and motionless so that no joint could be bent, whilst they lay motionless as stocks or stones. Fearful fits of vomiting often concluded these attacks. Sometimes they were dumb for days and could only gibber and mow with blazing eyes and slabbering lips, sometimes they were deaf so that even a pistol fired close to their ears had not the slightest effect.[78] Often they became fantastically excited, gesticulating wildly and shouting incessantly. Their voices were, however, not their normal tones nor even those of children at all, but the strong, harsh, hoarse articulation of rough and savage men. For hours together they would blaspheme in the foulest terms, cursing and swearing, and bawling out such hideous obscenities that the neighbours took to flight in sheer terror at the horrible scenes, whilst the distracted parents knew not whence to turn for help or comfort. Not only did the sufferers use the filthy vocabulary of the lowest slums, but they likewise spoke with perfect correctness and answered fluently in different languages, in French, Latin, English, and even in most varied dialects of Spanish and Italian, which could by no possible means have been known to them in their normal state. Nor could they at any time have heard conversation in these languages and subconsciously assimilated it. A famous case is on record where a servant girl of mean education fell ill and during a delirium began to mutter and babble in a language which was recognized as Syriac. This was considered to be accounted for when it was discovered that formerly she had been in service in a house where there was lodging a theological student, who upon the eve of his examinations used to walk up and down stairs and pace his room saying aloud to himself Syriac roots and vocables, which she thus often
