Seite 428 - That in the great majority of these mines night-work is a part of the ordinary system of labour, more or less regularly carried on according to the demand for coals, and one which the whole body of evidence shows to act most injuriously both on the physical and moral condition of the work-people, and more especially on that of the children and young persons.
Seite 494 - We are of opinion that if the result produced by such a combination is either a new article, or a better article, or a cheaper article to the public, than that produced before by the old method, that such combination is an invention or manufacture intended by the statute, and may well become the subject of a patent.
