On Vaucheria. — Professor Leidy recently made some remarks 

 before the Academy of Natural Sciences in Philadelphia on the 

 intra-cellular circulation of plants, as exemplified in the hairs of 

 the Mullein, the leaf cells of Vallisneria, &c. The moving streams 

 of protoplasm he likened to amgeboid movements, and expressed 

 tlie opinion that they were of the same character. In the common 

 Alga, Vaucheria, the filaments of which consist of very long cells, 

 comparable to those of Nitella or Chara, he had observed an ap- 

 parent motion of the cell contents, which is somewhat peculiar, 

 and, at least, is not generally mentioned by writers. The wall of 

 the cells is invested on the interior with a layer of tenacious proto- 

 plasm, containing the thinner liquid cell contents as nsual. The 

 parietal protoplasm is closely paved with green granules, and these 

 appear very slowly, but incessantly, to change their position in re- 

 lation with one another. The motion is so slow that it was a ques- 

 tion for some time whether it did actually occur, but it appears 

 sufficiently obvious if observed in relation with the lines of a mi- 

 crometer, and its existence was confirmed by several friends whose 

 attention was directed to it. — " American Naturalist," viii., 444. 



[Without calling in question the occurrence of '' Ameeboid 

 movements " in some Algse, it may be well to caution our readers 

 against the conclusion that therefore they are allied to Amceha. 

 This is the more necessary since so accomplished an observer as 

 Professor De Bary permitted himself to be mistaken as to certain 

 " Amseboid movements " in the Myxogastres, and but too hastily 

 declared their affinity with Amceba, a position from which he had 

 ultimately to withdraw. The term " ameboid " requires to be 

 accepted with a qualified interpretation. — Ed. Grev.]
