Ophthalmologist Nathaniel L. MacBride discusses the various maladies of the eye - first published in 1897, this book offers insight into the history of ophthalmology and eye medicine. Beginning with an anatomical discussion of the cornea, iris and conjunctiva, the author goes on to discuss the various ailments afflicting the eye, such as glaucoma and conjunctivitis. The second part of the book details the physics of eyesight, and how one can discern disturbances to the eye's function, such as the appearance of cataracts. As this book dates to the late 19th century, the treatments described have long been obsoleted. The application of cocaine solution upon the eye for instance has no place in modern ophthalmology. The surgical techniques of the time were conducted manually and with metallic instruments; such methods are outdated in the modern day.

Today, air-to-surface vessel (ASV) radars, or more generally maritime surveillance radars, are installed on maritime reconnaissance aircraft for long-range detection, tracking and classification of surface ships (ASuW - Air to Surface Warfare) and for hunting submarines (ASW - anti-submarine warfare). Such radars were first developed in the UK during WWII as part of the response to the threat to shipping from German U-Boats. This book describes the ASV radars developed in the UK after WWII (1946-2000) and used by the RAF for long-range maritime surveillance.
