Muh. ; C. vulpina, L., so exactly the European plant, that there 
can be no doubt of its correct determination in Ohio, and that the 
hesitation expressed by Dr. Boott in Richardson’s Arctic Expedi- 
tion, p. 466, is groundless, especially from any supposed resem- 
blance to C. stipata, Muh., as the two are vastly different; C. 
Davisii, Tor. ; C. longirostris, Tor. ; and C. recta, Boott. |

tents of very manifold characters, namely: 1. A peculiar, unt 
formly divided, granular mass. 2. This mass encompassed by 
small groups of an oval or fusiform shape. 3. Fusiform bodies, 
invested with a structureless membrane. 4. Developed psor0- 
spermatic corpuscles. ‘These different objects are found wholly 
or partially in one and the same cyst. The mature psorospel- 
mial corpuscles usually contain three to five baton-like or ellip- 
soid or globular diaphanous corpuscles which are structureless; 
they usually have also a rather large nucleus. The diaphanous 
corpuscles are seen moving and springing in their capsules, ana 
the nucleus is thereby moved about hither and thither. Such 
kidneys contain also free amcba-like corpuscles, and gregarilia 
like bodies largely nucleated,” rs 
These formations are by no means common,—our author hav- 
ing found them in four cases only out of a thousand specimess 
he has examined. 
But in other animals, and in other organs he has found similat 
formations, as have others, such as Miller, Gluge, Leydig, be 
im. In fact, these psorospermial forms occur in both a free 
and a cystic state in different tissues. eae 
The question is certainly a most interesting one: What signif 
a 
cation shall be put upon these singular animal-like forms? ” 
this is only one passage in the comprehensive question, What at 
most infusorial forms not evidently of a vegetable nature which 
every microscopist meets with perhaps daily in his studies? Th@ 
subject certainly is not yet ripe for decision, but we may allude 
it in a suggestive point of view. Both Kauffmann and Lieb i 
kihn, in watching these Psorospermia in glasses on their tables,
