Galileo G. Dialogues concerning two new sciences

Translated by Henry Crew & Alfonso de Salvio, William Andrew Publishing, 300 pp.
This work (1638) is about Galileo's experiments in bodies and motion. The publisher is not wrong at all in calling this work the given title of ".Two New Sciences". If anything it is Galileo's and his original Publisher's fault for naming both works in such a similar fashion:"Dialogues Concerning Two." The biggest difference is in the last words of title.
