P. S.

Did you not write a work on
the "plants of Wisconsin?" I would
like to have you send that also.

Can you make some exchanges
for fossils and fossil coal plants
of my locality? some fine
"Sigillaria" Picapteris, and
Lepidodendron, Calamites,
Productus Cora, P. Punctatis
Spirifer Cameratus etc etc

Send me a box of yours
and I will fill and return
