ANATOMICAL. 213 



and multiplying by the number of divisions covering tlio 

 mass, we can accurately determine both size and number. 



Now we pass on to the most important part of all 

 tli at which the wise King of Israel called " the golden 

 bowl " (Eccles. xii. 6), the human brain. Let us suppose 

 we have before us a tolerably large slice, a horizontal 

 section, properly and delicately prepared with red injec- 

 tion, giving it all the appearance of life. It is from the 

 cerebrum, or front, or proper brain, that which constitutes 

 the intelligent part of the medium of rnind. It is covered 

 with an extremely fine network of capillaries, which, 

 having taken up the red injection, and which in the living 

 being would have been the channels taking blood-nourish- 

 ment to every cell of the brain, gives to this deeply inte- 

 resting object close resemblance to life, motion excepted. 



Have you ever thought of that wonderful property 

 which we call memory ? What is memory ? How is 

 it that, every particle of the human body bone, muscle, 

 skin, nail, and brain being changed once every four 

 years, now science thinks, but even should it be seven, 

 as it was said to be years ago, a man of seventy years 

 of age has had at least ten different bodies, and lost ten 

 different brains, which certainly have been the instruments 

 employed in recollection, how is it that he can better 

 remember some of the events which happened during the 

 life of brain number one than in brain number nine ? 



Our bodies change repeatedly, so remember that it is 

 literally as well as metaphorically true that we " die daily." 



Look at this slice of the human brain. It consists of 

 a countless number of very minute cells. Our magni- 

 fying glass, called a " sixth" with the strongest eyepiece, 

 called the " D," or fourth, will, with an extended draw- 

 tube, give us a power much beyond a million of times, 

 and yet are we far from success in detecting the structure
