 do most of all dish'ke to be called upon to exercise. 

 To this kind of feeling Mr. Cook's lectures appeal, 

 and the peculiar character of his success seems to 

 show that he knows well how to deal with it. In 

 a moment of winning frankness he exclaims : " Do' 

 you suppose that I think that this audience can be 

 cheated ? I do not know where in America there 

 is another weekly audience with as many brains in 

 it ; at least, I do not know where, in New England 

 I should be so likely to be tripped up, if I were to 

 make an incorrect statement, as here." 1 After 

 this coaxing little dose, Mr. Cook proceeds to show 

 his respect for the learning of his audience in 

 some remarks on bathybius, which, as he conde- 

 scendingly explains, is a name derived from two 

 Greek words, meaning deep and sea ! I The pro- 

 found knowledge of Greek thus exhibited is quite 

 equalled by his account of bathybius from the 

 zoological point of view. He begins by telling his 

 hearers that, in a paper published in the " Micro- 

 scopical Journal " in 1868, Professor Huxley " an- 

 nounced his belief that the gelatinous substance 

 found in the ooze of the beds of the deep seas is a 

 sheet of living matter extending around the globe."
