One of the boys with him mentioned the brilliant colour of the red coats of the soldiers, but Dalton said that they looked the colour of grass. All the other boys laughed at him, and this made him think that his eyes differed from theirs. But he was not finally sure of this until he was twenty-six, when his attention was fixed on some flowers. Much later in life he gave this account of what he saw:I accidentally observed the colour of the flower of the geranium by candle-fight in the autumn of 1792. The flower was pink, but it appeared to me almost an exact sky-blue by day. In the candlelight, however, it was astonishingly changed, not having then any blue in it, but being what I called red. I supposed that the change of colour would be equal for all, and I requested some of my friends to observe it. But I was surprised to find that they all agreed that the colour was not much different from what it was by daylight.In another statement about his colour-blindness Dalton wrote: Pink appears by daylight to he sky-blue, a little faded(褪色的);by candle-light it has an orange or yellowish appearance.Crimson(深红色)appears a muddy( 泥土般的)blue by day, and crimson wool is much the same as dark blue. The defect(缺陷) in Dalton s eyesight led to an exchange of letters with one of his friends. Dalton had written: “I boldly state that pinks and roses are light blue by day, and a reddish yellow by night, and that crimson is bluish(带蓝色的)dark colour. His friend made fun of this: “I find by your accounts that you must have very imperfect ideas of the charms which causes beamy in the female. I mean that rosy blush(红润脸色)of the cheeks which you so admire for being light blue. The letter then continued that if Dalton knew of a girl with such an exceptional complexion(肤色), she would be “A fitter object for show than for a wife.1.

I wished that someday Id marry and have six children, and at Christmas my house would be full of energy and love. I found the man who shared my dream, but we had not expected the possibility of infertility(不能生育). So we applied for adoption(收养)and, within a year, he arrived. We called him our Christmas boy bemuse he came to us during that season of joy, when he was just six days old. Then nature surprised us again. In rapid succession(连续)we added two biological children to the family-not as many as we had hoped for, but compared with my quiet childhood, three made an entirely satisfactory crowd. As our Christmas boy grew, he made it clear that only he had the ability to select and decorate(装饰) the Christmas each year. He rushed the season, starting his gift list before we d even finished the Thanksgiving turkey(火鸡). He pressed us into singing carols(圣诞颂歌), our poor voices comparing with his musical gift of perfect voice. Each holiday he stirred us up, leading us through round of merry confusion. Our friends were right about adopted children not being the same. Through his own unique heredity(遗传), our Christmas boy brought color into our lives with his good cheer. He made us look and behave better than we were. Then on his 26th Christmas, he left us as unexpectedly as he had come. He was killed in a car accident on an icy Denvery street, on his way home to his young wife and three-month-old daughter. But first he had stopped to decorate our tree. His father and I sold our house, where memories filled every room. We moved to California leaving behind our friends and church.1.
