congenital spinal stenosis
stenosis of the vertebral canal present at birth; recorded in calves.

Next day the posters appeared in due course, and the public were informed, in all the colours of the rainbow, and in letters afflicted with every possible variation of spinal deformity, how that Mr Johnson would have the honour of making his last appearance that evening, and how that an early application for places was requested, in consequence of the extraordinary overflow attendant on his performances,--it being a remarkable fact in theatrical history, but one long since established beyond dispute, that it is a hopeless endeavour to attract people to a theatre unless they can be first brought to believe that they will never get into it.
A white ass, but not an albino, has been described without either spinal or shoulder-stripe; and these stripes are sometimes very obscure, or actually quite lost, in dark-coloured asses.
With respect to the horse, I have collected cases in England of the spinal stripe in horses of the most distinct breeds, and of all colours; transverse bars on the legs are not rare in duns, mouse-duns, and in one instance in a chestnut: a faint shoulder-stripe may sometimes be seen in duns, and I have seen a trace in a bay horse.

Instead of being hurt, denying, defending himself, begging forgiveness, instead of remaining indifferent even--anything would have been better than what he did do--his face utterly involuntarily (reflex spinal action, reflected Stepan Arkadyevitch, who was fond of physiology)--utterly involuntarily assumed its habitual, good-humored, and therefore idiotic smile.
Picture to yourself the unilateral development, the imminent danger of a spinal curvature.
James Torry could not think of taking Maggie as a nursery governess, even temporarily,--a young woman about whom "such things had been said," and about whom "gentlemen joked"; and Miss Kirke, who had a spinal complaint, and wanted a reader and companion, felt quite sure that Maggie's mind must be of a quality with which she, for her part, could not risk
