THE SEVEN FACTORS OF LIFE 89 
conclusion we can reason out, will have to do, often in 
more ways than one, with one or more of the Seven 
Factors of Life, which may be tabulated conveniently 
as follows :— 
1. Respiration. 
2. Nutrition. Which are concerned with 
3. Growth. the Preservation of the 
4. Protection. Individual. 
5. Rest. 
6. Reproduction. ; ; : 
Whe care of the Which are concerned with the 
Children. Preservation of the Race. 
We must bear them in mind always in our work, 
and we must never forget for a single moment that the 
Scheme of Creation is founded, not upon self-seeking, 
but upon co-operation. 
Whether we study Nature in order to become a 
professor or merely as a recreation, we must recollect 
that as students our object is to become acquainted 
with the ways of Nature, to find out what our organism 
does, why it does it, and how. We must, whenever it 
is possible, see and do, or at any rate try to do, things 
for ourselves ; we must stick resolutely to one job at a 
time ; we must not be led away by side issues; and 
finally we must never undertake more than we can 
reasonably expect to be able to do properly.
