Excerpt from An Account of Spina Bifida: With Remarks on a Method of Treatment, Proposed by Mr. Abernethy For a considerable space, and the opening will be found covered only by a very thin, tender skin, and so transparent, that the contents may be seen through it and this covering is doubtless a production of the duramatral coat of the medulla spinalis; but this will be noticed when the treatment of the disease comes under consideration. Sometimes, how ever, the common integuments are perfect, and of their naturai thickness and opacity.
