          the transcription will take time. Mrs. Perceval
being a pupil of Mr. Pursh, the manuscript
was given her as a favor, the authenticity
of which cannot be doubted. She further
hopes to accompany this catalogue by a
list of the plants she has been enabled herself
to collect in the course of one Summer around
Quebec, any specimens of which or the whole
are at Dr. Torrey's service if worth his acceptance.
The Fungi have given considerable
trouble from the circumstance of not
knowing how to preserve them best; but
to the whole of Cryptogamia Mrs. Perceval
will now bestow considerable attention, in
the hope of their being acceptable to Dr. Torrey.
