Summary
Emma and Leonard have scarlet fever.
Houstonia seems "a grand case"; J. T. Rothrock should publish his observations on the two pollens and the reciprocal action of two hermaphrodites.
Rhexia glandulosa offers nothing odd, but Heterocentron will turn out something marvellous like Lythrum.
Would like to know what AG thinks of last chapter of Orchids.
