-The code excerpt presented above uses the mirror to //introspect// on an object and uses the ''listSlots'' meta-method. The result is a table of the slots (fields and methods) provided by this object. Notice that fields are represented as a combination of an accessor and a mutator method, conforming to the Uniform Access Principle as discussed in chapter 5. Also note that the object has a field called ''super'', although this field was not explicitly defined. In AmbientTalk, ''super'' is defined implicitly for every object.

 The code excerpt below shows how one can add and remove slots to and from an object, and how one can explicitly access values and invoke methods upon an object, reflectively:

-This part of the tutorial has provided a basic feeling of how AmbientTalk's default mirrors can be created and the kind of power they offer. The default mirrors offer a much wider range of capabilities than those presented in this section, however. A complete overview of all meta-operations will be presented in the final chapter of this tutorial.
+This part of the tutorial has provided a basic feeling of how AmbientTalk's default mirrors can be created and the kind of power they offer. The default mirrors offer a much wider range of capabilities than those presented in this section, however. To get a complete overview, try to inspect AmbientTalk's prototypical mirror, named ''defaultMirror'', e.g. by using introspection:
+<code>
+defaultMirror.listSlots.map: { |slot| slot.name }
+</code>
+A complete overview of all meta-operations will be presented near the end of this chapter.
