Extract

A few years ago the author's attention was drawn to a signed and dated quadrant which is in a private collection in California. Since the writer cannot claim to know much (let alone to understand the working) of astronomical instruments, it seemed logical to look around and offer its publication to an expert. Unfortunately, no one has so far expressed any enthusiasm or interest. But the quadrant bears the signature of a well-known astrolabist and is dated; its publication, therefore, seems desirable.
