cuticle of living leaves, each cell at length giving origin to a 
zoosporangium from which numerous zoospores eventually proceed 
and pierce the cuticle of fresh leaves and there reproduce 
zoosporangia. Zoosporangia set free by the decomposition of the 
tissues of the leaf.

(Read 13th January, 1876.) 
Last season I brought before the Club some particulars relating 
to this interesting district. The subject was not quite exhausted, 
though the leading features and much of the history were touched, 
some further discoveries have been made, and increased attention 
given to the remains that are still in process of discovery in the 
mining district. 
The Club has also visited the mining district in one of its ex- 
cursions, seen the Roman remains collected at the smelting mill 
_at Charter-house, and also examined the process of washing the 
lead, or rather the ancient slimes, which have been left by the 
Roman workers, who seem to have possessed themselves of all the 
ore near the surface, but have left not only in their smelting, but 
also in their washing, enough to render the re-smelting and re- 
washing remunerative.
