They rowed through the narrow canal skirting the garden out into the expanse before the Giudecca, and then struck across the lagoon towards Fusina, past the island-church of San Giorgio in Alga, whose beautiful tower has flushed and darkened in so many pictures of Venetian sunsets, and past the Austrian lagoon forts with their coronets of guns threatening every point, and the Croatian sentinels pacing to and fro on their walls.
The water is as transparent as rock crystal, but like that mineral slightly distorts the object unless the view is absolutely vertical. It is a lens perfect in its limpidity. Here is a buff-coloured block roughly in the shape of a mushroom with a flat top, irregular edges, and a bulbous stalk. Rich brown alga hangs from its edges in frills and flounces.
The greatest mortality is due to childbirth a strange fact, as in the East confinements are generally easy. The practice in use here has probably much to do with this unfavourable result. After her confinement the woman is placed upon an alga or small native bed; underneath which, fire with aromatic herbs is so arranged as almost to suffocate the newly-delivered woman.
And on the face of the matter there is no ground for refusing to admit that Heteromita may be related to Chlamydomonas, as the colourless fungus is to the green alga.
This process may be repeated ad infinitum, unless we get to true organic atoms, the true gemmules, whatever they may be, and they necessarily will be incapable of any process of spontaneous fission. It is remarkable that Mr. Darwin brings forward in support of gemmule fission, the observation that "Thuret has seen the zoospore of an alga divide itself, and both halves germinate."
And if there be any parasitism in the matter, it is by no means of the alga upon the animal, but of the animal, like the fungus, upon the alga. Such an association is far more complex than that of the fungus and alga in the lichen, and indeed stands unique in physiology as the highest development, not of parasitism, but of the reciprocity between the animal and vegetable kingdoms.
In due time carefully prick out, and the task so interesting to watch is performed. The Garden. By A.H. BRECKENFELD. Nearly a century ago, Vaucher, the celebrated Genevan botanist, described a fresh water filamentous alga which he named Ectosperma geminata, with a correctness that appears truly remarkable when the imperfect means of observation at his command are taken into consideration.
And so, after all, we do not think we have lost any greater thing in not seeing the sunset from the Gardens, where half a dozen artists are always painting it, or from the quay of the Zattere, where it is splendid over and under the island church of San Giorgio in Alga. It is only the English and the other tourist strangers who go by upon the Grand Canal during the day.
Great stress is laid by the materialists on the changeability of certain microscopic forms, and the startling metamorphoses they apparently undergo in different infusions, especially those forms having developmental tendencies towards fungi and certain low forms of algA|. They attribute their different modes of branching, articulation, segmentation of filaments, etc., both to intrinsic tendencies and extrinsic causes, the latter depending, no doubt, in a great measure upon the chemical changes constantly taking place in their respective infusions.
Thus Salisbury has indicated the palmella gemiasma, which is found with us in places perfectly free from malaria, while it is often wanting in malarious marshes in the center of Italy; Balestra, a species of alga which is as yet indeterminate; Bargellini, the palmogloea micrococca; Safford and Bartlett, the hydrogastrum granulatum; and Archer, the chitonoblastus oeruginosus.
