                      2: Suppose you wanted to combine two files?  No editor command you
                      3: have learned so far will do that. The command 'r' is just what the doctor
                      4: ordered.  It reads in a file, without throwing away the existing buffer.
                      5: So, for example,
                      6:   ex para1
                      7:   r para2
                      8:   w both
                      9:   q
                     10: will edit "para1"; then read in "para2" at the end; and then
                     11: write the combined stuff on "both".  Try that, with those names,
                     12: in this directory.  Then type "ready".
                     13: #create Ref
                     14:    We say that matter is anything which occupies space and has
                     15: weight.  Matter possesses inertia, which is a resistance to change
                     16: of position or motion.  It may be acted on by forces which may set
                     17: it in motion, or change its motion.  While all these statements
                     18: are descriptive of matter, they do not provide us with a completely
                     19: satisfactory definition.  Scientists, with their great knowledge
                     20: of the properties and behavior of matter, are not yet able to
                     21: define it precisely.  Nature still holds many secrets to challenge
                     22: the minds of men.
                     23:    The quantity of matter which a body possesses is known as its
                     24: mass.
                     25:    When one end of a long glass tube that is open at both ends is
                     26: placed in water, forces cause the water to rise in the tube to a
                     27: certain height.  The finer the bore of the tube, the higher the
                     28: water rises.  A tube with a hairlike bore is called a capillary
                     29: tube and the liquid rise in it is called capillarity.  How could
                     30: you show that this rise is not due to atmospheric pressure?
                     31:    Seemingly, water rises in capillary tubes because the adhesive
                     32: forces between glass and water molecules are greater than the cohesive
                     33: forces between water molecules.
