I am inclined to attach some importance to the new system of manufacturing; and venture to throw it out with the hope of its receiving a full discussion among those who are most interestedin the subject.

The errors which arise from the absence of facts are far more numerous and more durable than those which result from unsound reasoning respecting true data.

There are few circumstances which so strongly distinguish the philosopher, as the calmness with which he can reply to criticisms he may think undeservedly severe.

As soon as an Analytical Engine exists, it will necessarily guide the future course of the science. Whenever any result is sought by its aid, the question will then arise — by what course of calculation can these results be arrived at by the machine in the shortest time?

Whenever the work is itself light, it becomes necessary, in order to economize time, to increase the velocity.

I wish to God these calculations had been executed by steam.

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.
