SCIENCE AND PSEUDO-SCIENCE. 207 



On June 22d one satellite will be on the east of Jupiter, and the 

 other three on the west, all in a bunch, and close to the planet. 



Of course, since the motions of the satellites, particularly of the 

 inner ones, are very rapid, their positions are continually changing, 

 and their configurations are different every night. I have merely 

 indicated their places for a few evenings, in order that the observer 

 may be able to recognize the satellites when he sees them. If he has 

 any doubt about his identification of them, or thinks they may be 

 little stars, he has only to carefully note their position and then look 

 at them again the next evening. He may even notice their motion in 

 the course of a single evening, if he begins early and follows them for 

 three or four hours.

SCIENCE AND PSEUDO-SCIENCE. 



By Professor T. H. HUXLEY. 



IN the opening sentences of a contribution to the last number of 

 this Review, the Duke of Argyll has favored me with a lecture on 

 the proprieties of controversy, to which I should be disposed to listen 

 with more docility if his Grace's precepts appeared to me to be based 

 upon rational principles, or if his example were more exemplary. 



With respect to the latter point, the duke has thought fit to entitle 

 his article "Professor Huxley on Canon Liddon," and thus forces 

 into prominence an element of personality which those who read the 

 paper which is the object of the duke's animadversions will observe 

 I have endeavored, most carefully, to avoid. My criticisms dealt 

 with a report of a sermon, published in a newspaper, and thereby 

 addressed to all the world. Whether that sermon was preached by A 

 or B was not a matter of the smallest consequence ; and I went out 

 of my way to absolve the learned divine to whom the discourse was 

 attributed from the responsibility for statements which, for anything 

 I knew to the contrary, might contain imperfect, or inaccurate, repre- 

 sentations of his views. The assertion that I had the wish or was 

 beset by any " temptation to attack " Canon Liddon is simply contrary 

 to fact. 



But suppose that if, instead of sedulously avoiding even the ap- 

 pearance of such attack, I had thought fit to take a different course ; 

 suppose that, after satisfying myself that the eminent clergyman 

 whose name is paraded by the Duke of Argyll had really uttered the 

 words attributed to him from the pulpit of St. Paul's, what right 

 would any one have to find fault with my action on grounds either 

 of justice, expediency, or good taste ? 



Establishment has its duties as well as its rights. The clergy of 

 a state Church enjoy many advantages over those of unprivileged 

 and unendowed religious persuasions, but they lie under a correlative
