AZEREDO (Francisco de)
PÁRA-Raios: Estudo Theorico e Pratico. Porto: Typographia de António José da Silva Teixeira, 1895.
X, 194, 8 pp., 10 est.: il.; 235 mm.
A very interesting study on the lightning rod, published at a time when the development of the technique was apparently stagnant and there were several voices against its infallibility, at the same time that studies on electricity were multiplying. The work deals with placement techniques, scientific aspects, etc., and is illustrated separately with 10 prints. Very rare.
