...Koussevitzky's interpretation may be subject to personal criticism, but it is a warm, lyric approach that does full justice to the cyclical construction and almost earthy quality of the music. For, despite name, the Requiem is not sorrowful or morbid, but confident and reassuring. Particularly fine were the male voices in the great fortissimo, "Behold, all flesh . . . ," and Radcliffe attained equal stature in the flowing fourth section and the final fugue. The impassioned soprano solos of Miss Frances Yeend lent the note of high personal achievement needed to round out a very satisfying concert...
...Bird. The scrotum system does not work with birds, because it might cause supersonic disturbances during flight. Birds' testes must be "faired into" the neatly streamlined body. But many birds breed in warm weather, even though their blood may get hotter than 42° C (107.6° F). How do they do it? Have their spermatogenic cells learned to work at high temperatures...
...Cowles believes (with most zoologists) that warm blood is a key factor in evolution. Like diesels and steam engines, animal mechanisms are more efficient at high temperatures. This is one of the chief reasons why mammals and birds, both warm-blooded, dominate the earth...
...Warm-blooded animals get around this difficulty in various ways. Some of the more primitive creatures become cooler at certain seasons, so that their testes can manufacture sperm. In higher animals the testes, contained in the scrotum, outside the body, are cooled by the air to a temperature lower than the body...
...Cowles thinks not. Last year, while dissecting Brewer's blackbirds (Euphagus cyanocephalus) he discovered that their testes moved downward and backward during the warm spring breeding season. In the new position they were "enveloped between the two dorsal folds of the abdominal air sacs." Cooled by circulating air, they could function properly, though the general body temperature might be much too high for them...
