denied they possess, was admitted to be different from locombllon. 

 As Dr. Pricliard had not displaced forest trees, shrubs and //- 

 chens from the third day' s creation, although in strictness none 

 of ihem come under the description of " grass, seed-bearing 

 herbs, or fruit-bearing trees:" — "on the same principle," I 

 observed, " it maybe thought that zoophytes might be permitted 

 to remain in the fifth day's creation, being 7noi>ing creatures that 

 have life, although their motion does not precisely accord with 

 the idea which, in opposition to the received translation, Dr. 

 Prichard thinks the Septuagint and the original convey." So 

 ftir is this passage from containing any assertion of the locomo- 

 tion of zoophytes, that it contains two admissions of the con- 

 trary. First, it is admitted by inference, that they do not in 

 strictness come under the description of locomotive animals; 

 and afterwards it is acknowledged that their motio7i does not 

 precisely accord with the idea {of locomotion) which Dr. Pri- 

 chard thinks the original text of Genesis conveys." 



A subtle or complex argument may, in consequence of mis- 

 conception, be misrepresented ; but of the process by which a 

 simple assertion is converted into a declaration totally different, 

 I do not pretend to anticipate the explanation.

VI. On the Diving-Bell, as a Means for curing Deafness. By 

 Dr. Hamel, of St. Petersburgh. 



To Mr. Tilloch. 



Sir, — W HF.N visiting the harbour which is now building at 

 Howth, near Dublin, I wished to make myself acquainted with 

 the manner in which the diving-bell for constructing the mason- 

 work under water is used, and obtained permission to descend. 



When the mouth of the bell was about two feet under wa- 

 ter, I began to feel pain in both ears, occasioned by the pres- 

 sure of the condensed air against the membrana tympani ; the 

 air in the inner cavity of the ear being of less density. Fear- 

 ing that this pain might become troublesome at a considerable 

 depth, I made exertions to admit air through the Eustachian 

 tube into the ear. I happened to accomplish this at first only 

 on one side, the air rushed into the cavicv of the right ear, and 

 the pain ceased instantly. As the bell continued g^ing down, 

 the pain returned; but as I repeated my exertions to open the 

 Eustachian tube, the air at intervals found its way through it, 



and
