'When, said he, 'the electrotype process first became known, it excited a very general interest; and although I was only a young student at Gottingen, under twenty years of age, who had just entered upon his practical career with a mechanical engineer, I joined my brother, Werner Siemens, then a young lieutenant of artillery in the Prussian service, in his endeavours to accomplish electro-gilding; the first impulse in this direction having been given by Professor C. Himly, then of Gottingen.
Although Schurig, Meckel, Himly, Taruffi, and others give bibliographic lists of diphallic terata, even in them erroneous references are common, and there is evidence to show that many cases have been duplicated under different names.
Were he attended the chemical lectures of Woehler, the discoverer of organic synthesis, and of Professor Himly, the well-known physicist, who was married to Siemens's eldest sister, Mathilde.
In 1848, when the war broke out with Denmark, he was sent to Kiel where, together with his brother-in-law, Professor C. Himly, he laid the first submarine mines, fired by electricity and thus protected the town of Kiel from the advance of the enemies' fleet.
The curious phenomena of colour-contrast illustrate momentary alterations of sensibility. These momentary modifications of sensibility are of no practical significance, being almost instantly corrected. Other modifications are more permanent. It was found by Himly that when the retina is overexcitable every stimulus is raised in the spectrum scale of colours. Thus, violet becomes red.
