    I had this clay, while visiting the collection in the Jarclin de3 Fig. 21. Fig. 24.—Fifth cervical vertebra with a congenital spDactylolysis lateralis s:nistra of the arch. a Posterior articular process b Inferior „ „ b' Posterior portion of the articular surface of the in- ferior articular process c Spine d Body e Interarticular portion f Transverse process x Spondylolysis of the fifth cervical vertebra. Plantes in Paris, the opportunity of personally examining the by Gruber (see Neugebauer, Archivjur Gyndkologie, Bd. xx., Heft 1, fig. 12), and the spondyloschiz:s lateralis sinistra of the Prague-Wurzburg pelvis. Nos. 77 and 78.—Fourth and fifth lumbar vertebrae with an extremely peculiar and unique form of spondylolysis. Whereas in general the fissure traverses the portio interarticnlaris of the arch, and the spine itself is generally divided into two parts, in this case the posterior span of the arch in both vertebras with the spine is perfectly developed, but the left inferior articular process of the fourth vertebra, and the left superior of the fifth, is formed of one single piece of bone. The condition of the sur- faces of separation of the central parts and the external appearance are direct evidence of a congenital condition. • The peripheral part3 of th's specimen, that is to say, the two isolated articular processes, have unfortunately teen destroyed. The fifth lumbar vertebra is depicted in fig. 25. No. 79.—Fifth lumbar vertebra of a child about ten years old, in which the posterior half of the arch cn the right side is an isolated piece of bone, united by ligamentary bands with the right interarticular portion, and with the pedicle of the spine on the left side. No. 80.—Fifth lumbar vertebra, with bilateral congenital interarticular fissure. Many of the last preparations are derived from the private stores of the servants of different anatomical institutions, where so many interesting specimens, carelessly thrown aside, are destined to be worked up into some heterogeneous skeleton or other. I also found some specimens among the vertebra in the collections of the Parisian dealers in natural history specimens. No. 81.—Bilateral interarticular spondyloschizis (the ongenital nature of which cannot be absolutely insisted on, because of some unfortunate fractures) in one of the lumbar verteb-a, which I found about three weeks ago during an inspection of the
