no perceptible change has taken place in the waters of the North Sea, 

 and the unscientific observer asks, "What has become of the waters of 

 the Baltic ? The answer is probably to be found in a simultaneous 

 phenomenon apparent on the Swedish coast, the gradual elevation 

 of which has been satisfactorily proved by the personal observation 

 of Mr Lyelh Recent observation, however, would seem to shew that 

 this elevation does not proceed at any regular or fixed rate, but, if 

 he might use the expression, ///wZ/y at uncertain periods, and at a 

 rate far greater than was at first supposed. At the same meeting, 

 when Baron Berzelius drew the attention of the Swedish Academy 

 to the diminution of water in the Baltic, a communication was made 

 from an officer who had been employed on the south-west coast of 

 Sweden, in the Skargard of Bohuslan, north of Gottenburgh, giving 

 evidence of the recent elevation of that part of the coast, and stating, 

 thatduringthe present summer, fishermen had pointed out to him near 

 the Mai Strom, at Oroust, shoals which had never before been visible. 

 The elevation of the Swedish coast forms a striking contrast with the 

 unchanged position of the contiguous coast of Norway, which, as far 

 as observation has hitherto been extended, has suffered no change 

 within the period of history, although marine deposits, found upon 

 the Norwegian Hills, at very considerable elevations above the level 

 of the sea, prove that those parts were formerly submerged. More 

 accurate information, however, will, before long, be obtained on this 

 interesting point, as a commission has been appointed by the Nor- 

 wegian government to investigate the subject, and marks have been 

 set up on the coast which will, in a few years, afford the desired in- 

 formation ; meantime, the Scandinavian peninsula presents an ex- 

 traordinary phenomenon ; the western, or Norwegian side, remaining 

 stationary, while the south and east, or Swedish sides, are rising, and 

 that, as the author had endeavoured to shew, at no inconsiderable rate.

 By MM. Gruby and Delafond. — Physiologists and anatomists have 

 long since proved the existence of certain entozoa in the nutritive 

 fluid of cold-blooded animals, such as frogs and fishes. Among the 

 Mammifera, also, worms have been sometimes found in the blood ; 

 but it is probable that they found their way thither merely by per- 

 forating the organs in which they were developed. It is of great im-
