a length of rather more than an inch, x 75.

Viburnum Lantana,x 2, Part of leaf of V. Lantana, x 75. 
Sambucus nigra, Linn. (Elder).—In the Elder the scales pro- 
tecting the bud are petioles. Externally are a pair of very smal 
brown scales; then a larger pair at right angles, then a pair muc 
more elongated, greenish, and with more or less developed leaves: 
In this respect they differ very much: sometimes there are three 
small points at the summit, sometimes a well-formed leaf, an 
every gradation between the two occurs. The two opposite 
leaves often differ considerably, and when one of the two has 1t8 
back to the main stem it is often much smaller than the outer 
one.
