This watering pot was invented by Dr. We-denbuch, of Wurtemberg. By the use of this, one part of manure to twenty parts of water, or charcoal powder at the same rate, is easily mixed by means of turning the spindle. The powder being perfectly mixed with the water has no time to settle before it is discharged where it is wanted. The effect of this manure is too well known to need mentioning here. It will be seen that the principle is somewhat like that of some churns. It has been much adopted in Germany.

By the use of charcoal powder the ammonia in the manure employed is absorbed and retained, and destructive properties are modified. - Deutcha Maganne, Stuttgard.

Dr. Hooker's beautiful Flora of Tasmania continues to appear with admirable punctuality.

Only the other day we announced the publication of the sixth part, with its charming figures of Tasmanian Orchids; and the seventh number is now before us, with a continuation of the Orchids and letter-press as far as the mosses, which have been entrusted to the care of Mr. Wilson, the learned muscologist. The drawings of Caladenia, an exquisite form of Australian Orchids, exceed in beauty anything which the work has yet produced.
