made his work much more complete. For example: among the 
CUBE published by Philip Miller, in the eighth edition of his 
Dictionary gti are Malpighia nitida and M. incana. Of the 
former, which h een somewhat misunderstood by more than 
one author, rag are good specimens in the Banksian Herbarium.

interpreted this plant seems doubtful. His description agrees with 
the type, except in one or two minor particulars; but we have not

In this memoir, which is a continuation of one by the same 
wane noticed on p. 453 of this Journal for 1898, an attempt is 
btain a clear idea of the molecular constitution of struc- 
tures exhibiting the phenomena of irritability. In all these cases 
a the

maintained that the several phenomena may be explained on the 
supposition of a closely similar molecular constitution. The ultimate
