WALL CREEPER. 
by Brlsson. In general, this bird is of a size 
between that of the Blackbird and of the 
'Sparrow. Total length, six inches and two- 
thirds : the bill, fourteen lines; and some- 
times twenty, according to Brlsson. The 
tongue is very pointed ; broader at the base, 
and terminated by two appendices. The tarsus 
is ten or twelve Hues ; the toes are disposed 
three before and one behind; the middle one 
nine or ten lines, the hind one eleven ; and the 
chord of the arc formed bv the nail alone is 
six lines. In general, all the nails are long, 
narrow, and hooked. The alai" extent is ten 
lines. The wing consists of twenty quills,

which is very short, and ought not to be 
reckoned a quill. The tall is twenty-one lines ; 
consisting of twelve nearly equal quills : it 
exceeds the wings six or seven lines.
