PINUS ABIES. ORD. 1. Conifera, — 5 
THIS tree somewhat resembles the former in its general appear- 
ance: the leaves are short, solitary, pointed, somewhat quadrangular, 
and upon the older branches incline in opposite directions: the cones 
are almost cylindrical, bent downwards, larger, and of a darker colour 
than in the preceding species. . 
Ray and Hudson mention this tree as a native of Scotland ; but 
we are told in the Flora Scotica that the P.sylvestris is the only species 
of pine that grows wild in that country. 
Upon an incision being made into the bark of this tree, a clear 
tenacious fluid issues, which concretes into a resinous substance, 
known by the name of resina abietis. This, after being boiled in 
water, and strained through a linen cloth, is called in the Pharmaco- 
peeias Pix burgundica, or Burgundy pitch. But if the boiling of the 
native resin is continued till the water is wholly evaporated, and 
wine vinegar is at this time added, a substance named Colophonium 
is formed. 
Burgundy pitch, which is chiefly imported from Saxony, is of a 
solid consistence, yet somewhat soft, of a reddish brown colour, and 
not disagreeable in smell. It is entirely confined to external use, 
and. was formerly an ingredient in several ointments and _ plasters. 
In inveterate coughs, affections of the lungs, and other internal com- 
plaints, plasters of this resin, by acting as a topical stimulus, are 
frequently found of considerable service.
