NOTE.— In a btter to Nature, (vol. 25, p. 124), Prof, Wil- 
liamson, to whose encouragement and advice we are much indebted, 
suggests that the generic name, Myriophylloides, should be changed 
to Helophyton. This he does on two grounds : — 1st, that Myrio- 
phylloides is likely to suggest improbable affinities, and 2nd, that 
Unger has already employed a very similar name — Myriophyllites 
— for a genus of Tertiary plants. We are are not quite convinced 
of the advisability of the change on the grounds specified, but bow 
to the superior judgment and maturer knowledge of our kind and 
genial leader. 
The question of affinities to which Prof. Williamson incident - 
ally alludes, can only be settled by the study of additional speci- 
mens ; but we may point out that the structure of the axis of our 
interesting fossil is strongly suggestive of Dicotyledonous relation- 
ships. 
ON CERTAIN DISCOVERIES OF BRONZE IMPLEMENTS IN THE 
NEIGHBOURHOOD OF LEEDS. BY JOHN HOLMES. 
Is May last (1881), a labourer in digging a trench by the side of 
an ancient foot-path going from the Carr Moor side, Hunslet, to 
Beeston Churwell and Morley, near Leeds, at about 10 feet 
6 inches deep in clay, came upon a hoard of nine bronze implements. 
Eight are of the Palstave and one of the Socketed Celt types — all of 
which I fortunately obtained and now exhibit. 
In May, 1878, in tunneling under the River Aire at Thwaite 
Gate, Hunslet, about a mile S.E. of the preceeding, at about 
20 feet deep in sand, a well formed spear head was discovered. 
Again in May, 1846, a discovery of bronze weapons occurred, when
