the projection, answering to one given elevati(5n, be first determined by experi- 

 ment, which the method supposes, the amplitudes in all other cases, where the 

 elevations and velocities do not very much differ from the first, may be deter- 

 mined, by the proportions here laid down, to a sufficient degree of exactness : 

 because, in all such cases, the effects of the resistance will be nearly as the am- 

 plitudes themselves ; and were they accurately so, the proportions of the ampli- 

 tudes, at different elevations, would be exactly the same as in vacuo. 



Mr. S. then proceeds to explain his method in several problems and corollaries. 

 But it will be read to more advantage in the author's volume of Select Exercises, 

 first published in 1752, where it was inserted, very much enlarged and improved. 



The Case of Henry /Oxford, who after having been dumb Jbr Years, recovered the Use 



of his Tongue by means of a Frightful Dream. By the Rev. Mr. Archdeacon 



Squire, F.R.S. N^ 486, p. i48. 



Henry Axford, son of Henry Axford, of the Devizes in Wiltshire, an attor- 

 ney, when a child wa« subject to convulsion-fits, which followed him pretty fre- 

 quently till he was about 25 years of age. After this, his health became ex- 

 tremely good. At about 28 years old, he perceived a hoarseness coming on 

 him, which was soon after attended with all the symptoms of a common cold, 

 till, in about 6 days after his first seizure, he became quite speechless, not only 

 losing the articulate use of his tongue, but being scarcely able to make the least 

 noise with it. His cold soon went off in the usual manner, and he got quite as 

 well in health as ever he had been in his life ; but still contiimed absolutely 

 speechless. He had advice from all the neighbouring physicians, but to no pur- 

 pose ; for nothing they did could restore him to the former use of his tongue. 



He continued in this dumb way about 4 years ; till one day in the year 1741, 

 he got very much in liquor, so much, that on his return home at night to the 

 Devizes, he fell from his horse 3 or 4 times, and was at last taken up by a neigh- 

 bour, and put to bed in a house on the road. He soon fell asleep ; when 

 dreaming that he was fallen into a furnace of boiling wort, it put him into so 

 great an agony of fright, that struggling with all his might to call out for help, 

 he actually did call out aloud, and recovered the use of his tongue from that mo- 

 ment as effectually as ever he had it in his life, without the least hoarseness re- 

 maining, or alteration in the old sound of his voice, as near as can be discerned. 

 And so it continued ever after. 



Concerning the Hearing of Fish. By Mr. JVm. Arderon, F.R.S. N"486, p. 149. 

 Though fishes are not provided with organs for hearing, similar to those serv- 

 ing to that purpose in other animals, Mr. A. observes it would be too presump- 

 tuous to declare, without experiment, that they are unable to hear, by organs
