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.

"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.
"I dare say, so I'll keep my flesh on, thank you.

You are so busy you can't read to a fellow, I suppose ?" asked Mac, whose eyes were better, but still too weak for books.
"Don't you want to come and join my class?
Uncle explains it all to us, and you can take a look at the plates as they come along.
