“Very much, auntie! It's all so wonderful, and so nicely planned, you can hardly believe what you see. Just think, there are 600,000,000 air cells in one pair of lungs, and 2,000 pores to a square inch of surface; so you see what quantities of air we must have, and what care we should take of our skin so all the little doors will open and shut right. And brains, auntie, you've no idea how curious they are; I haven't got to them yet, but I long to, and uncle is going to show me a manikin that you can take to pieces. Just think how nice it will be to see all the organs in their places; I only wish they could be made to work as ours do.” It was funny to see Aunt Myra's face as Rose stood before her talking rapidly with one hand laid in the friendliest manner on the skeleton's shoulder. Every word both the Doctor and Rose uttered hit the good lady in her weakest spot, and as she looked and listened a long array of bottles and pill-boxes rose up before her, reproaching her with the “ignorance and want of thought” that made her what she was, a nervous, dyspeptic, unhappy old woman. “Well, I don't know but you may be right, Alec, only I wouldn't carry it too far. Women don't need much of this sort of knowledge, and are not fit for it. I couldn't bear to touch that ugly thing, and it gives me the creeps to hear about 'organs,'” said Aunt Myra, with a sigh and her hand on her side. “Wouldn't it be a comfort to know that your liver was on the right side, auntie, and not on the left!” asked Rose with a naughty laugh in her eyes, for she had lately learnt that Aunt Myra's liver complaint was not in the proper place. “It's a dying world, child, and it don't much matter where the pain is, for sooner or later we all drop off and are seen no more,” was Aunt Myra's cheerful reply. “Well, I intend to know what kills me if I can, and meantime, I'm going to enjoy myself in spite of a dying world. I wish you'd do so too, and come and study with uncle, it would do you good, I'm sure,” and Rose went back to counting vertebrae with such a happy face, that Aunt Myra had not the heart to say a word to dampen her ardour. “Perhaps it's as well to let her do what she likes the little while she is with us. But pray be careful of her, Alec, and not allow her to overwork,” she whispered as she went out. “That's exactly what I'm trying to do, ma'am, and rather a hard job I find it,” he added, as he shut the door, for the dear aunts were dreadfully in his way sometimes. Half an hour later came another interruption in the shape of Mac, who announced his arrival by the brief but elegant remark, “Hullo! what new game is this?” Rose explained, Mac gave a long whistle of surprise, and then took a promenade round the skeleton, observing gravely, “Brother Bones looks very jolly, but I can't say much for his beauty.” “You mustn't make fun of him, for he's a good old fellow, and you'd be just as ugly if your flesh was off,” said Rose, defending her new friend with warmth.
