With this letter I send a good many bird skins; in the same box with them, there is a paper parcel containing pill boxes with insects.

The other pill boxes require no particular care.

You will see in two of these boxes some dried Planariae (terrestrial), the only method I have found of preserving them (they are exceedingly brittle).
By examining the white species I understand some little of the internal structure.

There are two small parcels of seeds.

There are some plants which I hope may interest you, or at least those from Patagonia where I collected every one in flower.
