 dently been perforated by the Tferedo (as some shells of these creatures were 

 found in the thickest part of the branch), before the barnacles took possession 

 of it. Barnacles are also found attached to other kinds of wood, particularly 

 to logs of mahogany, which from any accident have become adrift. The

" Remarks. In addition to the specific differences already given in p. 2105., 

 Professor Link (who calls this genus -4'bies) points out the following differ- 

 ences in the leaves, between it and the spruce fir : * The leaves do not grow 

 together, but are single, and have the usual form of single leaves ; the midrib 

 being only visible on the under side, and the upper side having a furrow down 

 the centre of the leaf. They are flat, and in two or more rows. In many 

 species, they are divided at the point. They are also of a very dark green 

 above, and have generally two strips of white on the under side, one on each 

 side of the midrib, which is not the case with the spruce.' (Abhand., &c., 

 p. 181.) 



" The Highland Society, in their list of premiums for 1 838, offer a medal 

 for the best account of the disease which has of late years attacked the stem, 

 larger branches, and occasionally the twigs, of the silver fir, somewhat re- 

 sembling the well-known rot of the larch ; with suggestions founded on expe- ,< . 

 rience, for checking the progress of the malady, or for preventing it. We had /s > 

 not before heard of this disease."
