ductively from the facts of his science, demonstrated, as he 

 believed, the existence and immortality of the soul and 

 looked upon its seat; this, notwithstanding it has often 

 been said that wherever there are three physicians there 

 are two atheists. Such an awe FraunhofTer felt when 

 the sun first wrote in brilliant colors on the spectrum the 

 secrets of its elements and told what the stars are made 

 of. Such an awe Agassiz felt when in his microscopic la- 

 bors he traced life down through the embryo, the egg, the

but which are not for ears untutored to their mysterious 

 melodies. 



Such harmony is in immortal souls, 

 But whilst this muddy vesture of decay 

 Doth grossly close it in, we cannot hear it. 



There is " an electric chain wherewith we are darkly 

 bound." There is a border-land of science, a dim, mys- 

 terious and shadowy realm. Into it brave spirits are con- 

 stantly making incursions, and the line between the 

 known and the unknown, between fact and mystery, has
