Black and white, carte de visite photograph of the feet of a boy aged seven years who was affected with myositis ossificans. The patient presented a series of lumps, apparently bony, along the margin of each latissimus dorsi, one in the left trapezius a little below the occiput, another in the right trapezius midway down the neck, and a third over the right supraspinous fossa. Another in the substance of the right triceps, reached from the posterior margin of the axilla nearly to the insertion of the deltoid. A saddle of bone covered the erector spinae on either side, and rendered the boy incapable of stooping. The right shoulder-joint was quite fixed, but there was a little movement in the left. There was no ossification of any of the muscles on the anterior surface of the trunk. There was no history of syphilis; parents healthy; grandparents on male side rheumatic. Photograph presented to the Museum by Thomas Sympson, Esq, surgeon to Lincoln County Hospital, Lincoln.
