and tingeing the hand like the celandine, or blood-wort, (sangui- 
nalis canadensis.) Hence the author names it Agaricus infector. 
Every part discharges this ichor, but it flows rather more copiously 
from the roots. In diflidence, however, it is added, this plant may 
possibly be passed over as the A. varius. The characters are, 
** Pileus—conical, one inch ocsasionally in diameter—pale gray, becoming 
ocherous, summit orange, flesh thin. 
“ Lamelle—fixed, white, four in a set, stained in places. 
“¢ Stipes—fistular, long, chestnut at the base, upwards pale brown ; root long, 
trailing, woolly.” 
At p. 378. we have a neat woed-cut of an agaric, which the au- 
thor has named A. surrectus, whose bulbous roots, and downy 
pileus, spring from the smooth summit of the Agaricus caseus, which 
has a uniform footstalk. The following characters are given to 
this new species : 
«* Pileus—convex, expanding, covered with a pile of short, white hair; centre 
depressed ; faintly tinted with yellow ; from one to three inches in diameter. 
“¢ Laminez—loose, irregular, generally four in a set, rather numerous, broad, 
white, changing to buff, and then pink. ; 
“¢ Stipes—solid, tapering upwards, rather thick immediately below the pileus, 
three inches high, thick as a reed, white, and often downy, wrapper at the base. 
“¢ Many of this species of singular plant,’’ continues the author, “ I found in 
October 1819, springing from a confluent mass of a. caseus. Bolton’s a. pulvi- 
natus is something like our plant; but he describes his under side as perfectly 
flat, and represents a singularity in the termination of his lamine, which is not 
observable in our a. surrectus.”’ 
The water-shrew, lately supposed by a correspondent in Lou- 
don’s Magazine to be an animal extremely rare in this country, 
appears to have been frequently seen by our author, though, with 
him, we strongly suspect that there are two species (Sorex fodiens, 
and S. Daubentonii) to be met with in England: one inhabiting 
clear fountains, and the other the fens in this gentleman’s neigh- 
bourhood, those of Lincolnshire, according to Pennant, and which 
we have seen on the moors of Lanarkshire. 

GEOGRAPHICAL COLLECTIONS. 
Voyage of the Astrolabe. 
We have had some difficulties to combat with, in the first number of these 
Collections, from the necessity of viewing travels in an historical light; for it is 
not with Geography as it is with Natural History, where the latest observations 
or facts may be immediately introduced under their separate heads. The travel- 
ler must be followed from the moment of his departure, through his toils and ex- 
ertions, to the end of his journey; and the results of his expedition must be care- 
fully analyzed, that the additions made to science, or to our knowledge of foreign 
_ parts, may be brought at once before our readers. They will not then be dis- 
satisfied if we refer to voyages which are now of some date; for though it will
