NOTES. CXXV 



von Herru Koch, in Alabama gesamraeltcn fossilen Knochenreste seines Hy- 

 drachus (tUe Basilosaurus of Harlan, 1835 ; the Zeuglodon of Owen, 1839 ; 

 the Squalodon of Grateloup, 1840 ; the Dorndon of Gibbes, 1845), read in 

 the Royal Academy of Sciences at Berlin, April June 1847. These valuable 

 fossil remains of an animal of the ancient world, which were collected in the 

 state of Alabama (in Washington County, not far from Clarksville), have be- 

 come by the munificence of our King, since 1847 } the property of the 

 Zoological Museum at Berlin. Besides the remains found in Alabama and 

 South Carolina, parts of the Hydrachus have been found in Europe, at Leog- 

 nan near Bordeaux, not far from Linz on the Danube, and, in 1670, ia 

 Malta.

 Contest respecting priority relative to the knowledge of the earth's compres- 

 sion, in reference to a memoir read by Huygens, in 1669, before the Paris 

 \cademy, was first cleared up by Delambre, in his Hist, de 1'Astr. mod. T. i. 

 p. Iii. and T. ii. p. 558. Richer's return to Europe took place indeed in 1673, 

 but his work was not printed until 1679 ; and as Huygens left Paris in 

 1682, he did not write the Additamentum to the Memoir of 1669, the publi- 

 cation of which was very late, until the period when he had already before 

 his eyes the results of Richer's Pendulum Experiments, and of Newton's great 

 work, Philosophise Naturalis Principia Mathematica.
