254 OF THE UNITY OP THE DEITY. 



ed according to the same laws, as the light of a candle. 

 The velocity of the light of the fixed stars, is also the same 

 as the velocity of the light of the sun, reflected from the sa- 

 tellites of Jupiter. The heat of the sun, in kind, differs 

 nothing from the heat of a coal fire. 



In our own globe the case is clearer. New countries are 

 continually discovered, but the old laws of nature are always 

 found in them: new plants, perhaps,, or animals, but al- 

 ways in company with plants and animals, which we al- 

 ready know : and always possessmg many of the same gen- 

 eral properties. We never get among sucii original, or to- 

 tally different, modes of existence, as to indicate, that we 

 are come into the province of a different Creator, or under 

 the direction of a different will. In truth, the same order 

 of things attends us, wherever we go. The elements act 

 upon one another, electricity operates, the tides rise and 

 fall, the magnetic needle elects its position, in one region 

 of the earth and sea, as well as in another. One atmos- 

 phere invests all parts of the globe, and connects all ; one 

 sun illuminates ; one moon exerts its specific attraction upon 

 all parts. If there be a variety in natural effects, as e. g. 

 in the tides of different seas, that very variety is the result 

 of the same cause, acting under different circumstances. 

 In many cases this is proved ; in all is probable. 



The inspection and comparison of Uvins[ forms add to 

 this argument examples without number. Of all large ter- 

 restrial animals the structure is very much alike. Their 

 senses nearly the same. Their natural functions and pas- 

 sions nearly the same. Their viscera nearly the same, both 

 in substance, shape, and office. Digestion, nutrition, cir- 

 culation, secretion, go on, in a similar manner, in all. The 

 great circulating fluid is the same : for, I think, no differ- 

 ence has been discovered in the proportion of hlood, from 

 whatever animal it be drawn. The experiment of transfu- 

 sion proves, that the blood of one animal will serve for an- 

 other. The skeletons also of the larger terrestrial animals, 

 show particular varieties, but still under a great general 

 affinity. The resemblance is somewhat less, yet sufficiently 

 evident between quadrupeds and birds. They are all alike 

 in five respects, for one in which they differ. 



Jnjisk, which belong to another department, as it were, 

 of nature, the points of comparison become fewer. But we 

 never lose sight of our analogy, e. g. we still meet with a 

 stomach, a liver, a spine ; with bile and blood ; with 

 teeth ; with eyes — which eyes are only slightly varied from 

 04ir own, and which variation, in truth demonstratesj net
