Yet most unhappily, as both sun and tide mounted, Christine moved faster, just too fast for her mud-clogged boots. The aerial roots, pale wands hanging plumb-straight down from the upper tree, betrayed her, and she did indeed fall plump into that vile black stinking mud, angering the small fishes that skipped on its surface, the many kinds of crab, and the little mud-tortoises that preyed on both. Stephen lurched forward to heave her out - met with the same fate - and they wallowed painfully, slowly, on all fours to the extreme edge of the mangrove trees, where clean water and a fairly clean bottom allowed them to crawl ashore in a very distressing state of filth.
She gasped, begged his pardon, said, 'How I hope we did not disturb him - probably not - there is two hundred yards to go. Does nakedness worry you?'
'Not in the least. After all, we are both anatomists.'
'Very well,' said she. 'There is nothing for it. We must both strip and rid our clothes of mud, our bodies of leeches. We have clean water here, thanks be: and in my pocket there is salt for the leeches, in a corked bottle. May I give you a hand with your boots?' She did so; he did the same for her; and they stripped off their clothes without the least ceremony, floating the mud out of them, weighing them down with stones; and then they attended to the astonishingly numerous and avid leeches, each dealing with the other's back in a wholly impersonal manner.
Apart from some artists' models and nations that possessed no clothes at all, Stephen had never seen anyone so unconcerned with nudity: and on reflection he remembered her brother Edward, his intimate friend, telling him that he and she had bathed, naturalised and fished, wearing nothing at all, from small childhood to maturity, in the isolated lake that formed part of their family's park. Well before this, during his first visit, she and her black companion had wandered into his field of vision as he searched the farther shore of a mere for birds and he had admired not only their freedom but also the combination of green, black, white, and the whiter than white of an egret, yet as objectively as he watched duck and cormorants. But now her tall, graceful, willowy shape was emphasised by the thin vermilion streams that flowed from the leech-bites (it did not coagulate, the creatures injecting a substance that thinned the blood, turned it a fine vermilion and allowed them a much longer period of feeding) and these outlined the curve of her long, long legs with an extraordinarily pleasing effect; and now something of the scientist, something of the pure anatomist, began to leave him.
