of these walls; neither has hoop iron been used in the house in the usual way, but the external angles being in concrete, we have inserted iron straps to unite these piers with the hexagon walls. Where the foundations can be depended upon, this bonding at the angles is all that is necessary, for, as you say, “it is almost impossible for a hexagon wall to fail if the foundation is good, and the tubes set in cement." Where, however, bond would be required, as in the case of uncertain foundation, holes are left in the hexagon tubes, that the hoop iron may pass through the concrete filling, thus making a far more effective bond than the mere laying in the joint, as usual in brickwork. The iron standards mentioned as occasionally introduced in the 4in. garden wall, are let into concrete (not into " granite ") blocks, and the filling-in of the tubes is of concrete made with Portland cement, and not with lime.

We would take this opportunity of mentioning that we have found this system to offer many advantages not noticed in the article. Besides being drier and lighter than brickwork, it is also stronger and more quickly erected ; walls of tubes and concrete preclude waste, and the use of rubbish. Such walls are also more durable, because about 75 per cent. of external wall surface is composed of the most indestructible materials, namely, concrete faced with flint, granite, &c., whilst the remaining 25 per cent. is a burnt clay almost equal to terra cotta. For these reasons this "combination of materials is well suited for facing seaside houses, and in all damp and exposed situations ; whilst for the construction of embankments or wharf walls, we have had an opportunity of practically testing its value. Previous to commencing the house Bickley we made numerous experiments, and satisfied ourselves as to the advantages we have indicated. These experiments were officially inspected by Mr. Vulliamy, the architect to the Metropolitan Board of Works, and upon applying for permission to adopt this system within the district we immediately received the formal sanction of the Board.

ON THE AURORA BOREALIS AS A

WEATHER PROGNOSTIC. SIR,--As a proof of the accuracy of the writer in the MECHANICS' MAGAZINE of September 18 last, who says that the aurora is a sign of south-westerly gales, I may mention that I observed one on the evening of October 19, 1865. There was an annular eclipse of the sun near sunset on the same evening. The light was very visible, streaming off from the surface of the moon, of a slightly yellow hue. The air was clear, but loaded with vapour on the point of condensing. I infer that the light was absorbed in the upper regions before it reached the surface of the earth. As the condensation proceeded, it became refracted, as a number of concentric arches of different hues, in the N.E. horizon, from which streams diverged towards the zenith, mostly of a brilliant red or crimson hue. Those which take place in spring, during the prevalence of the N.E. wind, present the appearance of an irregular bank of light. It was followed by violent south-westerly sweep across the Atlantic to Europe. As such driving bands is also reduced.
