The Brain and Spinal Cord of the Rabbit. It will be found 

 helpful to have at hand a well-mounted skeleton of a cat or 

 rabbit. Note carefully (a) the cavity of the cranium, (b) the 

 cavity in the spinal column, and (c) the sides of each neural

 the sides of the backbone. This can be done rapidly by making 

 long, deep cuts with the cartilage knife along the sides of the 

 backbone, in the planes indicated in the accompanying figure.
