o PBOCEEDINGS OF THE 



March 3rd, 1904. 



Prof. Sydney H. Vines, P.E.S., President, in the Chair. 



The Minutes of the last Meeting were read and confirmed. 



Mr. George Herbert Powler, Rev. Henry Thomas Spuiford, 

 and Mr. James Hornell were elected Pellows of the Society. 



Mr. L. A. Boodle, P.L.S., exhibited photographic lantern-slides 

 demonstrating the formation of secondary wood in certain regions 

 of the stem of Psilotum triqueirum. In parts of the rhizome 

 immediately below the aerial stems, and at the base of the aerial 

 stems themselves, tracheides occur, often in considerable numbers, 

 outside the primary wood. These external tracheides are found 

 to be still in course of development, as shown by the imperfect 

 lignification of their walls, at a time when the primary wood has 

 long been completed ; in some cases the external elements of the 

 wood further show a distinct radial arrangement. These stems 

 thus exhibit distinct remains of the secondary vascular tissues 

 characteristic of the Palaeozoic Sphenophyllales, with which on 

 various grounds there is reason to believe the Psilotacese to be 

 allied. 



A discussion followed, in which Dr. D. H. Scott, Mr. C. B. 

 Clarke, and the President joined.
