CONTRIBUTIONS TO THE FOSSIL FLORA OF HALIFAX. PART IV. 
BY THOMAS HICK, B.A., B.Sc, AND WM. CASH, F.G.S. 
Since our last communication on the Fossil Flora of Halifax was 
read before this Society, the work of investigation has gone on as 
regularly as circumstances would permit, and results of greater or 
less value have been obtained. These results have been summarised 
in two reports, which in conjunction with Prof. Williamson, F.R.S., 
we have presented to the British Association. As these reports 
show, few striking novelties have been unearthed during the last 
two or three years, the specimens collected having added but few 
forms that were not previously known. Nevertheless the accumu- 
lation of specimens, even of well-known plants, has not been 
altogether without value, inasmuch as we have thereby obtained a 
clearer insight into the structure and affinities of these than we 
previously possessed. In this direction then, if in no other, some 
advances of importance have been made, and it is the object of this 
paper to refer to one or two points in connection therewith. 
Calamites. 
Of the numerous genera of fossil plants whose organization has 
been made out with any degree of satisfaction, one of the best 
known is that of Calamites. Nevertheless, owing to the fact that 
few specimens have been met with in which the cortical tissues are
