One of the pieces of educational experiment apparatus used at The Fourth Higher School. This item is a sextant; a small device that measures the altitude of celestial bodies. It was used in chogaku (mechanics) for surveying education. These devices were used to determine the latitude and longitude of an observation point during a voyage. The outer arc has a scale of 0°-60°, and there is a fixing frame that connects it to the center part. The name sextant derives from the fact that the arc is one-sixth of a full circle. The fixing frame is positioned vertically, and the reflecting mirror is rotated while viewing the image of the horizon through a telescope using the light passing through the semi-transparent mirror. Light from a celestial body (star) is reflected by the reflecting mirror and semi-transparent mirror, entering the telescope and forming an image. When this image and the image of the horizon overlap, it means that the altitude of the celestial body is equal to twice the rotation angle. A detailed explanation can be found in Adolphe Ganot's physics book. This item was manufactured by Heath & Co. Ltd., London, UK.

Established in 1989 to preserve and utilize valuable materials handed down from the predecessor school when the university campus was relocated from Kanazawa Castle Site. Former teaching materials such as beautifully shaped physics experiment apparatus and mushroom moulage specimens that allow you to observe mushrooms as they were 100 years ago are fun-to-see natural museum materials in the museum's collection. The museum also holds many archive such as timetables that show the hard work of medical students 100 years ago, as well as archaeological materials excavated within the campus.
