Fig 1

(after Bolk)

Bolk illustrated his communication by four coloured figures which represent different ages in sequence. In fig. 1 one sees from below upwards, cartilage centres in the cervical vertebrae, separate on the two sides but connected together dorsally by a spinal membrane; above the vertebrae on each side one sees cartilage in a somewhat broad sheet forming-what appears to be the side of a foramen magnum, and connected together about their middle by a narrow bar of cartilage from which a small process ascends. Below this bar is an uncoloured area, Bolk’s spino-occipital membrane, which is continuous with the spinal membrane below and contains two small nodules of cartilage. Above the transverse bar above mentioned is a transversely placed separate mass of cartilage.
