Dmitry Mendeleev (1834-1907) throughout his life believed that his periodic table can be supplied with new elements not only from the further end of it but from the beginning as well. He made notes in 1870s-80s suggesting that there could be an element before hydrogen. By the end of 19th century when inert gases were discovered as a group this ideas became more topical. As a result this work was created. Although the
attempt of placing aether before hydrogen wasn’t successful Mendeleev managed to study rarefied gases and described the conditions of their conducts.
