Extract published in its own right from the Opera Philosophica published in Amsterdam by Blaeu in 1668, appeared in 2 vols. divided into 8 parts, which were also sold separately. Here I am including all of the great physical and mathematical writings philosopher, less well known as a mathematician, constituting the first volume, composed late in life after his return to England [some when Hobbes was even eighty-four]. The edition was published in Holland out having been barred from appearing in England; and they are found mostly specimens [like this] grouping, academic writings or philosophical ones, in separate sections.

De Natura Aereis browned, but still good specimen. Zeitlinger, n. 1945 [il solo primo vol.].
