distinct, not inerely from the Yorkshire whale, but from our 

 Sydney whale also ; which last, however, in this respect 

 agrees remarkably with the one described by Beale, so far at 

 least as we can make out from that author's description. In 

 all three whales I believe the foramen for the passage of 

 the spinal cord to be widest as it passes through the atlas 

 and other cervical vertebrae, from which it tapers away 

 until it terminates about the commencement of the caudal 

 vertebrae.
