They relate to the development and strength software of Charles Babbage's calculating engines, significantly the variation Engine and the extra advanced Analytical Engine, which used to be to be programmed utilizing punched playing cards. The publication additionally contains correspondence with contributors of clinical societies, in addition to complaints, catalogues and drawings. incorporated is an entire catalogue of the drawings of the Analytical Engine.

Those who may desire to study the principles of the Jacquard-loom in the most effectual manner, viz. that of practical observation, have only to step into the Adelaide Gallery or the Polytechnic Institution. In each of these valuable repositories of scientific illustration, a weaver is constantly working at a Jacquard-loom, and is ready to give any information that may be desired as to the construction and modes of acting of his apparatus. The volume on the manufacture of silk, in Lardner's Cyclopaedia, contains a chapter on the Jacquardloom, which may also be consulted with advantage.

It holds a position wholly its own; and the considerations it suggests are most interesting in their nature. In enabling mechanism to combine together general symbols in successions of unlimited variety and extent, a uniting link is established between the operations of matter and the abstract mental processes of the most abstract branch of mathematical science. A new, a vast, and a powerful language is developed for the future use of analysis, in which to wield its truths so that these may become of more speedy and accurate practical application for the purposes of mankind than the means hitherto in our possession have rendered possible.
