to avoid all metal fittings that might influence the

contained all sorts electrical measuring devices, including
several kinds galvanometers, Wheatstone bridges, and large
selection meters use the Edison lighting system.
Building was established the chemical laboratory. There
were also numerous condensers, induction coils, relays, and
electro-mechanical assemblies hand. It
was fitted with balance room and lined with shelves
containing bottles chemicals. The "galvanometer room" the early plans for the
lab was now made into separate building, completely dedicated
to electricity. was constructed deep foundation of
brick and cement that would dampen any shocks the delicate
electrical measuring equipment inside.
