It has long been known that the leaves of these plants, and of several allied species, are attacked by a fungus, the mycelium of which spreads in the leaf passages, and gives rise to powdery masses of orange yellow spores, arranged in vertical rows beneath the stomata: these powdery masses of spores burst forth through the epidermis, but are not clothed by any covering, such as the Æcidia of Peridermium Pini, for instance.
Among his papers was found a Greek and Latin index to Hippocrates, more copious and exact than that of Pini, which he had finished only a year before his death.
Between the blisters are the minute spermogonia, b. It is thus seen that the fungus Peridermium Pini was regarded as a parasite of pines, and that it possessed two varieties, one inhabiting the leaves and the other the cortex: the "varieties" were so considered, because certain trivial differences were found in the minute structure of the Æcidia and Spermogonia.
In other words, the fungus growing in the cortex of the pine, and that parasitic on the leaves of the groundsel and its allies, are one and the same: it spends part of its life on the tree and the other part on the herb. A spore of Peridermium Pini germinating.
This work, by Pini, a naturalist of reputation, is instructive in the geology of the country between Modena and Florence, of the Campagna, and of part of Naples; there are also remarks on the antiquity and extent of the Italian Volcanoes. Viaggio da Milano ai tre Laghi Maggiore, di Lugano, e di Como. Del C. Amoretti. Milan, 1803. 4to.
It is the song which accompanied the famous Calumet dance in celebration of the peacemaking qualities of tobacco-smoking. Min-tin-go mi-ta-de pi-ni, pi-ni hé! Ninahani, &c, ongo; ninahani, &c, hoho; ninahani, &c. Mintingo mitade Pini pini hé! Atchicha lé machi mi nam ba miktande, Miktande pini pini hé!
Oersted first proved that the other part of its life is spent on the leaves of certain Rosaceæ, and his discovery has been repeatedly confirmed. I have myself observed the following confirmation of this. Many other well established cases of similar heteroecism could be quoted. But we must return to the Peridermium Pini.
Cylindrical bark-borers, which are little, round, weevil-like beetles, are now flying about fruit trees, to lay their eggs in the bark. Associated with the Pissodes, we may find in April the galleries of Tomicus pini, branching out from a common centre. They are filled up with fine sawdust, and, according to Dr.
This mountain, rising from the shore of the Bay of Baiæ, was suddenly formed in September 29th, 1538, and rises to a height of 440 feet above the sea-level. It is a crater-cone, and the depth of the crater has been determined by the Italian mineralogist Pini to be 421 English feet; its bottom is thus only 19 feet above the sea-level.
If we had gone ashore in this place, all my precious collections would have been inevitably lost; but we ourselves could have scrambled easily to land, and re-embarked with Senor Honorio, who had remained behind in the Pini, and would pass in the course of two or three days. When night came I lay down exhausted with watching and fatigue, and fell asleep, as my men had done sometime before.
