Gratiolet, L. P. Recherches sur Fanatomie de FHippopotame, 
publiees par les soins du Docteur Edmond Alix. Paris, 
1867. 4to, pp. 405, with 12 plates. 
Gratiolet left behind him a manuscript containing the detailed 
account of his researches into the anatomy of a Hippopotamus 
which had died shortly after its birth. We are indebted to Dr. 
Alix not only for the publication of this manuscript, but also for 
completing some portions, as the myology of the hind limb, the 
anatomy of the organs of generation, &c., by his own examination 
of another example which died at about the same age.

The author became the proprietor of a whale, 55 feet long, 
which was thrown ashore on the western coast of Sweden ; he 
took great care to preserve an accurate account of it by draw- 
ing up detailed descriptions and preparing photographs of the 
specimen in its fresh state as well as after he had succeeded in 
mounting its skin and skeleton. He has also paid some atten- 
tion to the principal parts of its internal anatomy. Finding 
some slight discrepancies from the European species known, he 
considered it to be an unknown species, which he named 
Malmska Hvalen or Balanoptera Carolina ; however, zoo- 
logists specially acquainted with whales regard it as a Phy- 
salus sibbaldii. The first of the two publications referred to 
contains merely a preliminary notice of it. In the publication 
of the second work the author was liberally supported by his 
Government, and thus enabled to bring it out in a magnificent 
style. It contains a most detailed account of all the circum- 
stances connected with the preparation of the specimen, of its 
external appearance, skeleton, etc.
