A Median Incisor Tooth

Sir,?I would like to ask your readers for some reference to a case of a median incisor tooth if any of them are acquainted with one. Last year a prisoner in my jail was found to have what appeared to be one in the upper jaw. Situated between the two central incisors, which were very long and tush-like, and had their enamel worn away half way up, was a shorter rounded peg-like tooth which also had its enamel worn away for about half its length, and there were three upper molars on the right and only two on the leftside, but there were five, teeth in front of the canines. Below the teeth were normal except that there were only two molars on the right side. The man, a Kurmi, aged 40 years, said that the central tooth appeared after the two central incisors in boyhood. There was no family history of anything of the kind. In a female Ganjhoo (Kharwary), aged 17 years, 1 also found a conical tooth growing into the mouth from behind the left upper central incisor. The other incisors were normal. I can find no reference to a median incisor tooth in Quain's Anatomy or any other book at hand. I would like to mention that the commonly accepted notion of the teeth being more regularly arranged, and the wisdom teeth being less cramped and not so frequently absent in the lowor
