Mechanics’ Institutions were established in the hope of popularizing scientific knowledge, and incidentally making the workman better at his work. The latter motive at first received the chief emphasis. At Manchester, for example, the preamble declared that “this society was formed for the purpose of enabling Mechanics and Artizans of whatever trade they may be, to become acquainted with such branches of science AS [my emphasis] are of practical application in the exercise of that trade, that they may possess a more thorough knowledge of their business, acquire a greater degree of skill in the practice of it, and be qualified to make improvements and even new inventions in the Arts which they respectively profess.”

At Manchester, for example, the preamble declared that “this society was formed for the purpose of enabling Mechanics and Artizans ..., to become acquainted with branches of science such AS ??? are of practical application** in the exercise of that trade,...
2. Shouldn't that be 'so that' or 'in order that'? What's this problem called?
