Note 7 — Chapter IX
Reading edition
Footnote 7: Since writing this opinion I think, perhaps, it will be well to pause till the results of Professor George Forbes', F.R.S., experiments with a new stereoscopic instrument in South Africa are to hand; he is there at present by request of Lord Kitchener with his new invention. For full report of this instrument I would refer to Professor Forbes' paper read at the Society of Arts, December 18th, 1901. It is sufficient now to say that the instrument folds up to 3 foot 6 inches in length, can be used by one observer only standing, kneeling, or lying down, has great accuracy and portability, and has received the support of Sir George Clarke and other authorities.[Back to Main Text]
