The greatest desideratum of zoology is the power of examining 
some specimens of the genus Physeter, or Blackfish, as it is called 
by the whalers. There is not a bone, nor even a fragment of 
a bone, nor any part which can be proved to have belonged to a 
specimen of this gigantic animal to be seen in any museum in Euv-. 
rope. This is the more remarkable as the animal grows to the 
length of more than fifty feet, is mentioned under the name of the 
Blackfish in almost all the Whaling Voyages ; and two specimens 
ot it were examined by Sibbald, having occurred on the coast of 
Scotland. The only account which we have of the animal on which 
zoologists can place any reliance is that furnished by Sibbald in his 
‘ Little Tractate on Scotch Whales.’ 
Boyer, in the ‘ Nova Acta Naturze Curiosorum,’ describes a Whale 
found at Nice which has been thought to be a Blackfish, on ac- 
count of the position which he assigns to the blower; but the figure 
which he gives is so much like a bad design of a Spermaceti Whale 
(Catodon) in other respects, that it is doubtful to which genus it 
properly belongs. 
I am aware that in some catalogues of osteological specimens
