THE CELL 89 



in no way different from the other single cells leading a 

 single life in the water. That he is a very active animal 

 with organs of touch, locomotion, and a great number of 

 others to assist him in his life. Many male cells of plants 

 and animals swim about in the water for a long time and 

 long distances in se'arch of the female cell. It shows 

 clearly that at the start we are just what Prof. Drum- 

 mond stated, "Apparently no different from plants in- 

 sects, and animals." These tiny microscopic beings will 

 of their own free will go ahead and multiply into groups, 

 and tie and arrange themselves into the different shapes 

 and forms we afterwards call plants, animals or man. 



By this time, I think the reader must see that the cell 

 is the one who is at the base and is the cause of life that 

 we see, as in plants and animals. He is the cause of all 

 living structures. He multiplies by division, as heretofore 

 described, and with the building material at hand or fur- 

 nished by other cells, the work continues until the plant 

 or animal is completed. We see him move about from 

 place to place in search of food and material for his struc- 

 ture just as other animals do. 



We know that he requires food, air and water just as 

 we do. We know that he understands how to select the 

 right kind of material at the right time and with it, build 

 the most intricate and complicated structures. We know 

 this because we see him do it and from these facts, we 

 must naturally conclude that he acts in a similar manner 

 to other animals including man. We find that he acts for 

 a purpose. When man acts for a purpose, we say he is 

 intelligent. When a person is able to produce any struc- 

 ture by reason of being intelligent, we mean that he is 

 instructed or skillful in the particular work which he does. 

 When a large building is being constructed, it seems in
