Here Is a picture In which yon are oui>puoel to bo 

 Fookin^at them from Plato. You will also see a little 

 Work of the imagination here; a little villnprr: is inter- 

 posed, probably the dwelling's of inhabitants of the 

 moon who were to have received religions instruction 

 from the earth, for you perceive there is a church there. 

 [Laughter.] 



We will have a picture brought on showing the won- 

 derful wny in which the moon is covercil with craters. 

 It is different from the appearance of craters and moun- 

 tains as we picture them to ourselves. When YOU look at 

 that you will begin lo think that there is some other op- 

 eration at work there than that which produces our 

 mountains and the few craters we have. You seem to 

 have an appearance produced by boiling over, or the 

 pouring down of some very heavy rain, as a heavy rain 

 on a muddy sur 'ace produces pits like these. As regards 

 Dr. Hook's explanation, I need hardly say that bubbles 

 would probably not be formed so large as that, aud no 

 forms of matter known to us would be coherent enough 

 to form these of miles in extent. Wo seem forced 

 to a theory very startling, that we had on the moon's 

 surface a pounding down of meteoric missiles, not 

 necessarily solid ones, but a falling down of meteors on 

 the plastic surface. It seems to me to be the only theory 

 left. At the present day it is estimated that over 

 400,000,000 meteors fall through the day, but the result is 

 very slight indeed. I have found that the 

 earth would require 40X000,003 years to 

 have her diameter increased a single inch 

 by them. When wo look back upon the p;ist history of 

 our system, we see signs that there was a time when 

 larger meteors and more splendid comets were at hand 

 to be absorbed in the solar system. While tha earth was 

 still in a lorm of vaporous matter the moon was rolling 

 on, still plastic, and these meteors falling down upon 

 her surface would produce th u pitted appearance. 



I will have the room lightened up again while the 

 email lantern is prepared, and then I will have three 

 pictures of the residue from boiling a calcareous solution. 

 You will see how very much line my pictures are those 

 of the moon. I will undertake to s:iy that all those who 

 are not acquainted with every nook and cranny of the 

 moon will be deceived by these, especially the third and 

 last one. You will notice that there appear in them 

 eeas which have terraces around them. 



I will now invite you to notice what was suggested to 

 me by Dr. Bernard of Columbia College, that wo have 

 in the solar system the signs of a beginning and of an 

 end. Jupiter and Saturn have made progress to a 

 further state than the sun, but are etill full of life and 

 energy. Then In the progression comes our earth, and 

 Mars, and Venn B, and Mercury, which have lost most of 

 their Inherent heat. In the moon wo have a body seem- 

 ing to have lost all its inherent neat, and to have neither 

 water norair. All those sitrns of progression seem to 

 point to the day of creation and teach us to look forward 

 to the time when tln.se proee^s'-s liej_':ui. We seem to 

 see signs of benlnning. Tin-re must have been a begin- 

 nitigof those processes which in the moon have come to an 

 end. Looking forward we see that our sun the youngest 

 as it were, so far as sitfns of passing on at old age is con- 



will one day lose heat, and nil the other rriPTni^rj 

 of the solar system will have lost their.*. There sc^ms 

 to be an end of our solar system, a beginning and an end 

 marked, and in that respect astronomy differs from 

 other sciences, which give us no such signs of a begin 

 Ding or end. 



CALCAREOUS RESIDUE LIKE M*)OX PHOTOGRAPH. 



In this picture of the residue of a calcareous solution 

 before you, notice the black region around the crater 

 and signs of terraces. You have in the next picture no 

 terraces visible. Ninety-nine observers of the moon out 

 of a hundred would not be able to tell me that this is not 

 a photograph of some part of the moon's surface. 



There is one point I intended to touch on more fully. I 

 snoke of the possibility of any planet only being in- 

 tended to be inhabited during a short time of the exist- 

 ence of the planet, millions of years before it was lit, 

 being followed by millions of years after it became un- 

 fit for habitation. Lotus have an illustration of that. 

 If it were known that some gentleman in Brooklyn 

 only intended to remain at homo ton minutes on a 

 given day, and you did not know whether it was 

 morning, noon, or evening, and you called at random, 

 you would bo surprised to find him at home. Take any 

 particular time in the same way, and consider the 

 chances that the planet is inhabited in it. Tlio 

 chances are small; much more in favor of the present 

 moment belonging to the millions of years before or tho 

 millions of years alter it becomes fit for habitation 

 Th.it is the case with tho moon, I feel tolerably certain. 

 That the moon has long since passed the time when it 

 was lit to be tho abode of life w is touched upon in tho 

 second lecture, and that Jupiter and Saturn have not 

 reached tho time when they are fit. But though wo 

 are much more likely to see a planet when It is not lit 

 for habitation, we must take tho immense number of 

 them into consideration. There are millions of stars 

 and millions whicn no telescope can rovoaJ. 

 Aud you have the chances reversed; and though for
