Passing the façade of the Alhambra Court, we arrive at the Fountains, which at this end of the Nave correspond to those of the south end in position, and generally with respect to the aquatic plants which live in the water of the long basin. The two fountains here are designed and executed by Monti the sculptor. The figures of Syrens, supporting the large shells, typify by their colour four races of men: the Caucasian, white; the Nubian, black; the North American Indian, red; and the Australian, olive. The smaller figures above these bear fruit indigenous to various soils. The design of the Fountains is most appropriate, and the entire composition very artistic. The bronze colour of these statues, and of many others in the building, is produced by means of the electrotype process, with signal success. In the water which surrounds this fountain many interesting plants will be found, in addition to the lilies and other varieties which adorn the basin of the Crystal Fountain at the south end of the Nave. The Papyrus plant will be recognised by its tall green stems topped with fibrous leaves. The manuscripts of the Egyptians and many ancient nations were inscribed upon sheets made from the stalks of this plant. Many of the Egyptian architectural ornaments are derived from the form of the Papyrus, which grows in large quantities along the banks of the Nile. Rice, sugar-canes, and other interesting plants, grow along the margin of the water; the most curious of which, as indeed it is one of the rarest in the whole collection, is the Lattice Plant. This specimen was but lately brought from Madagascar by the Rev. Mr. Ellis. The remarkable form of the plant, from which it is named, will ensure its easy recognition. The gold fish, of which there are many thousands in the fountain basins of the Nave, have all been bred there from a few fish which have now grown to a great size, and may often be noticed steadily sailing amongst their multitudinous progeny. The temperature of the water, which is heated by water pipes beneath the surface, is peculiarly favourable to the growth of these fish. THE NORTH TRANSEPT, AND TROPICAL END OF THE BUILDING. It has been found that the valuable collection of Palms and other specimens of Eastern vegetation, which have been collected in this Transept and beyond, could only be kept healthy by isolating the department devoted to them, and raising its temperature to a degree which would not be pleasant in all parts of the building, or favourable to the equable growth and seasonable cultivation of the other various botanical specimens. During the greater part of the season, a curtain divides this portion of the Palace from the more temperate regions. The temperature suits so well the plants that some, which on their arrival appeared not to grow well, have become quite acclimated, wearing a rich and luxuriant growth of verdure.
