parchment. Until recently these pulvilli, 
which are furnished with innumerable 
hairs, were supposed to operate as suckers ; 
but the higher powers of the microscope 
have revealed, at the termination of each 
of the numerous hairs that cover the 
surface, a minute expansion, which is 
kept moist by a fluid exuding from the 
extremity; and the belief now prevails 
that, while each single hairlet serves as a 
sucking disk, the two pulvilli themselves 
act as cushions for the preservation of the 
larger hooks (which would otherwise be- 
come abraded), in a similar manner to 
the soft cushions that protect the sole of 
a cat’s foot, and enable it to tread so 
lightly. — ‘ Humble Creatures’ by James 
Samuelson and J. Braxton Hicks, M.D. 
ALEUCIS PICTARIA. 
When stars shine bright, though pale 
and cold, 
And rough winds, waiting at the 
birth 
Of Spring, the heir of Winter old, 
Dunce madly round about the earth ; 
Then, clad in suit of russet-grey, 
Piclaria sits upon the spray. 
When streams more musical do sound, 
Like joyous bells on New Year’s morn, 
Then merry men hie o’er the ground, 
With hearts all joy, like love new- 
born, 
To find, upon the blackthorn’s spray, 
Pictaria clad in russet-grey. 
Thou silent herald of long days, 
And flowers rich in every hue, 
And birds with all-expressive lays, 
To thee this visit is but due — 
Pictaria, clad in russet-grey, 
Sitting forlorn upon the spray.
