Question: CHAPTER XXIII 

Fischer, exactly one week after his nocturnal visit to Fourteenth Street, hurried out of the train at the Pennsylvania Station, almost tore the newspapers from the news stand, glanced through them one by one and threw them back. The attendant, open-mouthed, ventured upon a mild protest. Fischer threw him a dollar bill, caught up his handbag, and made for the entrance. He was the first passenger from the Washington Limited to reach the street and spring into a taxi. 

"The Plaza Hotel," he ordered. "Get along." 

They arrived at the Plaza in less than ten minutes. Mr. Fischer tipped the driver lavishly, suffered the hall porter to take his bag, returned his greeting mechanically, and walked with swift haste to the tape machine. He held up the strips with shaking fingers, dropped them again, hurried to the lift, and entered his rooms. Nikasti was in the sitting-room, arranging some flowers. Fischer did not even stop to reply to his reverential greeting. 

"Where's Mr. Van Teyl?" he demanded. 

"Mr. Van Teyl has gone away, sir," was the calm reply. "He left here the day before yesterday. There is a letter." 

Fischer took no notice. He was already gripping the telephone receiver. 

"982, Wall," he said--"an urgent call." 

He stood waiting, his face an epitome of breathless suspense. Soon a voice answered him. 

"That the office of Neville, Brooks and Van Teyl?" he demanded. "Yes! Put me through to Mr. Van Teyl. Urgent!"

Question: So ill he could not move, Wolfgang Amadeus Mozart supposedly sang parts of his final masterpiece, "Requiem," from his deathbed. Two centuries later, the exact cause of the Austrian composer's premature death, in December 1791 at age 35, is still a mystery. 

This portrait by painter Johann Georg Edlinger, showed Mozart not long before his mysterious death in 1791. 

Theories abound. It's known that his entire body was so swollen he couldn't turn over in bed; some say jealous rivals poisoned him, while others suggest scarlet fever, tuberculosis, or lethal trichinosis from undercooked pork. 

Now, new evidence points to an altogether different conclusion: Mozart may have died from kidney damage caused by a strep infection, possibly strep throat. Health.com: Can't stop coughing? 8 causes of chronic cough 

Dr. Richard H.C. Zegers of the University of Amsterdam and his colleagues analyzed data from Vienna's death registry. Researchers had not previously analyzed the daily death registry -- begun in handwritten script in 1607 and maintained until 1920 -- for clues to Mozart's death. 

Zegers and his team looked at information for 5,011 adults who died during three consecutive winters starting in 1790, as well as eyewitness accounts of Mozart's death, according to the study published this week in Annals of Internal Medicine. 

"By looking at the patterns of death during Mozart's time and combining them with the signs and symptoms of his final disease, we have not one but two pillars on which our theory is built," said Zegers. "Although we can't be 100 percent conclusive, I'm convinced that we have come very near the exact reason he died."  1. When did Vienna start their death registry?

Question: Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but the two are not equivalent. Frequency is an objective, scientific attribute that can be measured. Pitch is each person's subjective perception of a sound, which cannot be directly measured. However, this does not necessarily mean that most people won't agree on which notes are higher and lower. 

This creates a linear pitch space in which octaves have size 12, semitones (the distance between adjacent keys on the piano keyboard) have size 1, and A440 is assigned the number 69. (See Frequencies of notes.) Distance in this space corresponds to musical intervals as understood by musicians. An equal-tempered semitone is subdivided into 100 cents. The system is flexible enough to include "microtones" not found on standard piano keyboards. For example, the pitch halfway between C (60) and C♯ (61) can be labeled 60.5. 1. What is pitch?
