余の考案せる新型額帯反射鏡について

　額帯反射鏡は吾科領域に於て最も重要な器具であるにも拘らず，今日迄著明な変化は見られない。本邦に於ては海江田式等があるが，余は視野の拡大，両眼視，眼精疲労の軽減等を念頭に置き，次の如ぎ額帯反射鏡を考案した。

MIYAO devises a new type of head-mirror which affords a greater visual field, bilateral in vision and avoidance of visual fatigue. It is provided with light from electric bulb using 10 V of current either alternating or direct; the mirror itself is constructed with a radius of 600mm and with convexity whose focal po-int is at 300mm.
