Quote #25
The scent organ was playing a delightfully refreshing Herbal Capriccio—rippling arpeggios of thyme and lavender, of rosemary, basil, myrtle, tarragon; a series of daring modulations through the spice keys into ambergris; and a slow return through sandalwood, camphor, cedar and newmown hay (with occasional subtle touches of discord—a whiff of kidney pudding, the faintest suspicion of pig's dung) back to the simple aromatics with which the piece began. The final blast of thyme died away; there was a round of applause; the lights went up. In the synthetic music machine the sound-track roll began to unwind. It was a trio for hyper-violin, super-cello and oboe-surrogate that now filled the air with its agreeable languor. Thirty or forty bars—and then, against this instrumental background, a much more than human voice began to warble; now throaty, now from the head, now hollow as a flute, now charged with yearning harmonics, it effortlessly passed from Gaspard's Forster's low record on the very frontiers of musical tone to a trilled bat-note high above the highest C to which (in 1770, at the Ducal opera of Parma, and to the astonishment of Mozart) Lucrezia Ajugari, alone of all the singers in history, once piercingly gave utterance. (11.93)
Huxley makes it quite clear: technology is more capable than natural, human ability. The "scent organ" easily passes from the lowest note ever uttered by a human to the highest. On the other hand, the boundaries for high and low are still those that have been set by humans, very similar to the way science itself is bound by human invention.

"A New Theory of Biology" was the title of the paper which Mustapha Mond had just finished reading. He sat for some time, meditatively frowning, then picked up his pen and wrote across the title-page: "The author's mathematical treatment of the conception of purpose is novel and highly ingenious, but heretical and, so far as the present social order is concerned, dangerous and potentially subversive. Not to be published." He underlined the words. "The author will be kept under supervision. His transference to the Marine Biological Station of St. Helena may become necessary." A pity, he thought, as he signed his name. It was a masterly piece of work. But once you began admitting explanations in terms of purpose—well, you didn't know what the result might be. It was the sort of idea that might easily decondition the more unsettled minds among the higher castes—make them lose their faith in happiness as the Sovereign Good and take to believing, instead, that the goal was somewhere beyond, somewhere outside the present human sphere, that the purpose of life was not the maintenance of well-being, but some intensification and refining of consciousness, some enlargement of knowledge. Which was, the Controller reflected, quite possibly true. But not, in the present circumstance, admissible. He picked up his pen again, and under the words "Not to be published" drew a second line, thicker and blacker than the first; then sighed, "What fun it would be," he thought, "if one didn't have to think about happiness!" (12.39)
It's interesting that Mustapha thinks a discussion of purpose to be heretical. He worries that the idea of purpose will make people think about God, which means that his World State hasn't done a great job of satisfying man's larger questions, his grander curiosities. Thus, science has not been able to substitute religion. In this way, science has failed.
Quote #27
A V.P.S. treatment indeed! She would have laughed, if she hadn't been on the point of crying. As though she hadn't got enough V.P. of her own! She sighed profoundly as she refilled her syringe. "John," she murmured to herself, "John…" Then "My Ford," she wondered, "have I given this one its sleeping sickness injection, or haven't I?" She simply couldn't remember. In the end, she decided not to run the risk of letting it have a second dose, and moved down the line to the next bottle.
Twenty-two years, eight months, and four days from that moment, a promising young Alpha-Minus administrator at Mwanza-Mwanza was to die of trypanosomiasis—the first case for over half a century. (13.10-1)
This is a brilliant interruption to the rest of the story in Brave New World. We see that human life is utterly at the mercy of science. Of course, you could take a different point-of-view—even science is subject to the fallacies of human error.
