Read it through once

When I described Lucy’s symptoms--the same as before, but infinitely more marked--he looked very grave, but said nothing. He took with him a bag in which were many instruments and drugs, “the ghastly paraphernalia of our beneficial trade,” as he once called, in one of his lectures, the equipment of a professor of the healing craft. When we were shown in, Mrs. Westenra met us. She was alarmed, but not nearly so much as I expected to find her. Nature in one of her beneficent moods has ordained that even death has some antidote to its own terrors. Here, in a case where any shock may prove fatal, matters are so ordered that, from some cause or other, the things not personal--even the terrible change in her daughter to whom she is so attached--do not seem to reach her. It is something like the way Dame Nature gathers round a foreign body an envelope of some insensitive tissue which can protect from evil that which it would otherwise harm by contact. If this be an ordered selfishness, then we should pause before we condemn any one for the vice of egoism, for there may be deeper root for its causes than we have knowledge of.
