Peterkin was not satisfied.

The chemist said that all he had done ought to have taken out the
salt. The theory remained the same, although the experiment had
failed. Perhaps a little starch would have some effect. If not, that
was all the time he could give. He should like to be paid, and go.
They were all much obliged to him, and willing to give him $1.37
1/2 in gold. Gold was now 2.69 3/4, so Mr. Peterkin found in the
newspaper. This gave Agamemnon a pretty little sum. He sat
himself down to do it. But there was the coffee! All sat and
thought awhile, till Elizabeth Eliza said, "Why don't we go to the
herb-woman?" Elizabeth Eliza was the only daughter. She was
named after her two aunts,­Elizabeth, from the sister of her father;
Eliza, from her mother's sister. Now, the herb-woman was an old
woman who came round to sell herbs, and knew a great deal.
They all shouted with joy at the idea of asking her, and Solomon
John and the younger children agreed to go and find her too. The
herb-woman lived down at the very end of the street; so the boys
put on their india-rubber boots again, and they set off. It was a
long walk through the village, but they came at last to the
herb-woman's house, at the foot of a high hill. They went through
her little garden. Here she had marigolds and hollyhocks, and old
maids and tall sunflowers, and all kinds of sweet-smelling herbs,
so that the air was full of tansy-tea and elder-blow. Over the porch
grew a hop-vine, and a brandy-cherry tree shaded the door, and a
luxuriant cranberry-vine flung its delicious fruit across the
window. They went into a small parlor, which smelt very spicy.
All around hung little bags full of catnip, and peppermint, and all
kinds of herbs; and dried stalks hung from the ceiling; and on the
shelves were jars of rhubarb, senna, manna, and the like.
