The reason why I could not go naked was, I could not bear the heat of the sun so well when quite naked as with some clothes on; nay, the very heat frequently blistered my skin: whereas, with a shirt on, the air itself made some motion, and whistling under the shirt, was twofold cooler than without it.
Ráadásul a nap tüzét is sokkal nehezebben viseltem így, mint olyankor, ha némi ruha volt rajtam. Ha pedig légmozgás támadt, és meglebbentette a rajtam lévő inget, az duplán enyhítette a meleget.
