Every science is involved, and theology has come into conflict with metaphysics, logic, astronomy, physics, chemistry, geology, zoology, biology, history and even economics and medicine.
The advances in stellar photography made by Paul and Prosper Henry and others suggested to him the magnificent idea of obtaining, through the collaboration of astronomers in all parts of the world, an autographic picture of the entire sphere containing more than fifty million stars, which should faithfully record in future ages the state of the sky at the end of the i 9th century.
From the astronomers the Stoics borrowed their picture of the universe - a plenum in the form of a series of layers or concentric rings, first the elements, then the planetary and stellar spheres, massed round the earth as centre - a picture which dominated the imagination of men from the days of Eudoxus down to those of Dante or even Copernicus.

Thus has arisen in recent times what we may regard as a third branch of astronomical science, known as Stellar Statistics.
The principal modification is that,up to the present time, stellar astronomy has not advanced so far that a computation of the perturbations in each case of a system of stars is either necessary or possible, except in exceptional cases.
Moreover, the absence of sensible parallaxes in the stellar heavens seemed inconsistent with its validity; and a mobile earth outraged deep-rooted prepossessions.

There ensued a general classification of the stars by Secchi into four leading types, distinguished by diversities of spectral pattern; and the recognition by Huggins of a considerable number of terrestrial elements as present in stellar atmospheres.
C. Vogel published a modification of Secchi's scheme of stellar diversities, and gave it organic meaning by connecting spectral differences with advance in " age."
