12 "fHE COMING OF MAN 



cobweb of cells and fibers enveloping the body. This is a 

 well-formed and slightly organized and molded tissue, we might 

 almost call it an- organ. 



We may safely say that the protozoa have developed cells, 

 the units of structure whose combination made possible the 

 rise of higher forms. The ccelenterates have developed these 

 cells farther, have differentiated them by division of labor; 

 have builded the two absolutely essential organs, and have 

 furnished some most important tissues whose grouping, com- 

 bination, arrangement and shaping will make the efficient or- 

 gans of higher types. 



Here again as in bacteria and protozoa we find a small 

 amount of realization and attainment, and a great bundle of 

 vast but vague possibilities; their vagueness is a symptom of 

 the far higher new achievements which they were to attain. 

 They paved the way to greater and swifter, or at least less 

 wearisomely slow, advance. Or one might say that they laid 

 deep and solid foundations, and gathered an abundance of 

 material, so that their descendants might erect a fortress- 

 palace of strength and beauty. Despise not the day of small 

 things, greater things will come in time; and our wealth of 

 time is inexhaustible. 



Worms. A wise old German professor used to say with 

 whimsical exaggeration: '^ Study worms. If you know them 

 thoroughly, you will understand the whole animal kingdom. 

 If you do not study them carefully, you will never know any- 

 thing about zoology." He was right. In worms the possi- 

 bilities of lower animal life begin to emerge from vagueness, to 

 unfold and take form. We used to say: '' All things are 

 possible with God and in Austria"; we might add ''and among 

 worms." Still they belong to the great apostolic succession 

 of layers of foundations. Most of their forms are buried 

 beyond hope of recovery. 



They do not form a well-marked type, kingdom or group; 

 they are an assemblage of relics of a lost past. The study 

 of the group is like looking into our grandmother's china closet
