This is a reprint of Cohen's 1949 book. (Sansom wrote the foreward.) While amended in some respects by later work, there is a great deal here that is valuable and unique. Cohen provided much of the economic information for the U.S. Strategic Survey reports on Japan; this is much more detailed and comprehensive in most respects.

Having done a Ph.D. in optics, I have read quite some books on optics and out of curiocity I bought this book, but I am not very pleased with it. First, it is difficult to read because of the old English language and structure. For native English speakers this carries perhaps not so much weight, but for me it did. Second, because it is a collection of Newton's works, it contains of course also many not-so-interesting discussions which you have to 'consume' before realising it was not so interesting.

What is nice though, is that the book contains many so-called queries, which are possible explanations of various optical phenomena, explanations/assumptions Newton could not prove/disprove at the time. This is fascinating reading, because many of these turned out to be true (or false, but even then: still interesting to know what he thought).

Overall impression: if you are interested in the history of optics/Newton then it is a nice book. But just for browsing in the evening: no.
