The proportion between the velocity with which men or animals move, and the weights they carry, is a matter of considerable importance, particularly in military affairs.

The economy of human time is the next advantage of machinery in manufactures.

Another mode of accumulating power arises from lifting a weight and then allowing it to fall.

In turning from the smaller instruments in frequent use to the larger and more important machines, the economy arising from the increase of velocity becomes more striking.

As soon as an Analytical Engine exists, it will neccessarily guide the future course of science.

Errors using inadequate data are much less than those using no data at all.

That a country, [England], eminently distinguished for its mechanical and manufacturing ingenuity, should be indifferent to the progress of inquiries which form the highest departments of that knowledge on whose more elementary truths its wealth and rank depend, is a fact which is well deserving the attention of those who shall inquire into the causes that influence the progress of nations.
