The+Farewell

What


 * shows camaraderie that has developed between Helmholtz, Bernard, and John
 * explains why John must stay in London; Mustapha Mond wants “to go on with the experiment.”
 * the last appearances of Helmholtz and Bernard.
 * Illustrates how John feels about "civilization".

Why
 * shows beginnings of John’s self-harm/asceticism with induced vomiting
 * develops the Indians’ religious nature
 * describes a traditional Indian method to induce vomiting; mustard and warm water
 * further develops John’s disillusionment with BNW society

How
 * plot progression achieved mainly through dialogue between Helmholtz, Bernard, and John
 * ^^ therefore, in such a passage full of dialogue, the absence thereof, i.e. the silence between the three is effective in showing their bond, “There was a silence. In spite of their sadness – because of it, even; for their sadness was the symptom of their love for one another – the three young men were happy.”
 * John's method of purification by drinking warm water and mustard demonstrates his hate of civilization better than an explicit declaration.
