most infinitely in consistence, in shape, in structure, and 

 in function. In consistence, it is sometimes so fluid as 

 to be capable of forming in drops ; sometimes semi- 

 fluid and gelatinous ; sometimes of considerable resist- 

 ance. In shape for to Strieker the cells are now pro- 

 toplasm we have club-shaped protoplasm, globe-shaped 

 protoplasm, cup-shaped protoplasm, bottle-shaped proto- 

 plasm, spindle-shaped protoplasm branched, threaded, 

 ciliated protoplasm, circle-headed protoplasm flat, 

 conical, cylindrical, longitudinal, prismatic, polyhedral, 

 and palisade-like protoplasm. In structure, again, it is 

 sometimes uniform and sometimes reticulated into inter- 

 spaces that contain fluid. In function, lastly and here 

 we have entered on the consideration of faculty or power 

 some protoplasm is vagrant (so to translate wan- 

 dernd), and of unknown use, like the colorless blood- 

 corpuscles. 



In reference to these, as strengthening the argument, 

 and throwing much light generally, I break off a mo- 

 ment to say that, very interesting as they are in them- 

 selves, and as Recklinghausen, in especial, has made 

 them, Mr. Huxley's theory of them disagrees consider- 

 ably with the prevalent German one. He speaks of 

 them as the source of the body in general, yet, in his 

 Physiology, he talks of the spleen, the lymphatics, and 

 even the liver -parts of the body as their source. 

 They are so few in number that, while Mr. Huxley is 

 thankful to be able to point to the inside of the lips as 

 a seat for them, they bear to the red corpuscles only 

 the proportion of i to 450. This disproportion, how- 

 ever, is no bar to Mr. Huxley's derivation of the latter 

 from the former. But the fact is questioned. The 

 Germans, generally, for their, part, describe the color-
