MAMMALIA. 



Anchylosed Spine of Bull-Dog, — The enclosed note and illustration 

 are perhaps sufficiently interesting to publish. The photos show two 

 views of part of the spine of a Bull-Dog (female), said to be eight 



years old. Four of the lumbar vertebrae have become firmly anchylosed 

 together, the centra forming a single solid mass of bone ; yet the 

 articulation of the pre- and post-zygapophyses is quite normal, the 

 dry bones being quite separate there, as shown in the dorsal view. —
