this earth, vizjfthe resurrection of the Saviour^ is established 

 by the testimony of the three intellectual senses. In the 

 gospel of the evangelist St. John, we read, " But Thomas, 

 one of the twelve, called Didyrnus, was not with them when 

 Jesus came. The other disciples therefore said unto him, we 

 have seen the Lord. But he said unto them, except I shall 

 see in his hands the print of the nails, and put my finger into 

 the print of the nails, and thrust my hand into his side, I will 

 not believe. And after eight days again his disciples were 

 within, and Thomas with them ; then came Jesus, the door 

 being shut, and stood in the midst, and said, peace be unto 

 you. Then saith he to Thomas, reach hither thy finger, and 

 behold my hands ; and reach hither thy hand, and thrust it 

 into my side; and be not faithless but believing. And 

 Thomas answered and said unto him, my Lord and my God. 

 Jesus saith unto him, Thomas, because thou hast seen me, 

 thon hast believed ; blessed are they that have not seen, and 

 yet have believed." Thus was the fact of the resurrection 

 established by the evidence of so many of the senses, as to 

 render deception impossible. 



21. In some instances the touch itself, is liable to error. 

 For example(if we roll a pea, or a bullet, between two fingers 

 crossed, we receive the impression of two distinct objects, 

 though we know there is only one ; and if we look at it, at 

 the same time, the illusion is not removed, though we see at 

 once that it is an illusion. }. The organs here are, however, 

 placed in an unnatural position. Another fallacy occurs 

 with respect to heat. If we place the hand in separate ves- 

 sels, the one containing warm, and the other very cold water, 

 and after some time withdraw the hands, and immediately 

 plunge them in the mixture of both waters, to the one hand 

 the mixture appears warm, and to the other cold. So in a 

 tropical country, if one person descends a high mountain 

 from the regions of perpetual snow, and meets at the middle, 

 another ascending from the hot valley below, he who is de- 

 scending will feel oppressed with heat, while the other is
