by plants, to which he gives the general name of ( circumnutation.’ This 
term is employed to express the tendency of the different parts of plants in 
growth, to describe a series of irregular curves, loops, and zig-zags, by their 
movements successively towards all points of the compass. As we propose 
in the next number to have an article explanatory of Mr. Darwin’s views, 
we shall not attempt to discuss them in the space at our disposal here, 
The experiments recorded are of the most ingenious kind, and carried out 
with the utmost care, and with that attention to all minutiae which Mr. 
Darwin so well knows how to bestow upon the most complicated investiga- 
tions. Hundreds of figures, showing the tracks made by growing plumules 
and radicles, are reproduced in woodcuts, and we think that on inspecting 
them the reader will be rather surprised to find that Mr. Darwin has been 
able to evolve anything definite from such an apparent chaos.
