recent plants, wounds and pathological conditions frequently lead to the 
formation of unusually orientated and abnormal wood 1 . 
Such specimens as these wounded Calamites, reveal in a particularly 
striking fashion that we have in the fossil tissues the remains of plants 
which were once alive, combating with similar accidents in their environ- 
ment to those which assail the plants of to-day, and were stricken down and 
fossilized in the midst of their activities. This, as well as the great rarity 
of such structures in Calamites, must justify the present short note.

and associated secondary tissue cut off and isolated by (c) cambium, which has produced {a) additional 
tissue between the primary strands, and also (Y) inverted strands opposite them. Note the very wavy 
course of the cambium resulting from this.
