not easily believe what is beyond our own knowledge, but faith in the claims of Keely as a discoverer, if not as an inventor, is steadily increasing. The following from a foreign publication about the Keely Motor will be of interest to all who have watched the progress of that enterprise. The correspondent writes:--"In the following brief article I purpose placing the latest aspect of Mr. Keely, perhaps the best abused man in America, and his investigations before the readers of Anglo-Austria;" continuing,-- "Under the heading of 'The Keely Motor Again,' Invention, of London, on October 19th, printed a communication, mentioning the leading scientist of America, Dr. Leidy, of the University of Pennsylvania, as supporting Mr. Keely's claims as a discoverer of an unknown force, as follows:--Dr. Leidy having expressed the wish that Professor Barker should again visit Mr. Keely and witness the experiments which had convinced himself that Keely had discovered a new force, has received the following letter:-- "909, Walnut Street, Philadelphia, October 4, 1889. "Dr. Leidy. Sir,--Referring to our conversation of a few days since, and the suggestion of another visit to the workshop of Mr. Keely, by Professor Barker, I would say that I have presented the matter to Mr. Keely and he acquiesces in what I stated to you. That is to say, if Dr. Barker desires to visit Mr. Keely's workshops again, and will make this known to him in writing or through yourself, for the purpose of further observation and of having confirmed or removed from his mind, as the case may be, the conclusions or impressions arrived at by him, and published in the columns of the Ledger, of this city, in 1878; and on condition that he will, if his further observations satisfy him that he did injustice to Mr. Keely, forthwith publish that fact through the same channel, the Ledger: he being, of course, at full liberty to confirm by further publication his previous condemnation, if satisfied with the correctness of that conclusion; then Dr. Barker will be cordially received by Mr. Keely, and a series of experiments will be conducted for him at an early day, say, Saturday, 12 inst. And in the event of the engagement being made, I shall request the pleasure of your presence, and that of Dr. McCook. I leave the matter in your hands for such action as you in your wise discretion may think proper to take. Very truly yours, "Charles B. Collier." Nothing could be fairer than Mr. Keely's proposal, and the result of Professor Barker's visit will be watched for with the keenest interest by all scientists on both sides of the Atlantic. [7]
