afford a nearly certain remedy. I have found that an infusion of its dried leaves has little or no effect, but that a decoction has; from this, I suppose the active principle differs from tannin. Mr. Fitzgerald, of Wellington, offers a preparation of this useful plant, of which it is to be hoped the public will take advantage.

Rata (Metrosideros robusta).

The juice of the vine, obtained by cutting and inverting it, affords a strengthening, slightly astringent, beverage; very wholesome.

Pohutukawa (Metrosideros tomentosa).

The inner bark is reported to be useful for diarrhœa.

Rimu (Dacrydium cupressinum).

The gum of this tree is excessively astringent. The bark of the young tree was used by Maoris as a styptic, to stop the bleeding of wounds.

The capsules of Manuka (Leptospermum scoparium), and the gum of Cyathea medullaris (Punga), are also useful in attacks of diarrhœa.
