Sutherland on a Friday, and she had commanded him to send in his notes "before Monday." But, as ill luck had it, the Doctor was busy "in working at the cholera bacillus with a beautiful Vienna microscope purchased with this object." That would occupy him on Friday and Saturday, and Sunday was Sunday; so "the Viceroy must wait." The reader who remembers an earlier chapter will be able to imagine Miss Nightingale's wrath. Notes and telegrams, now withering, now pleading, followed fast upon each other. "I did not know the bacillus was of more consequence than a Viceroy." "If you did a little on Sunday, the Recording Angel would drop not a tear but a smile." But Dr. Sutherland was not to be cajoled into abandoning either his science or his Sabbatarianism; and on the former point he put in a very good plea in mitigation of judgment. If Dr. Koch's cholera bacillus turned out well, the discovery would save many more lives than Lord Dufferin, however carefully instructed, was likely to do. Miss Nightingale did not believe in the bacillus but allowed herself to be appeased, especially as it turned out that Lord Dufferin was not leaving London till a day or two later than she had supposed. So, she and Dr. Sutherland collaborated in indoctrinating their fifth Viceroy in the truths of their Sanitary gospel. There is a formidable list in her hand of "Papers for Lord Dufferin." As he was as good as his word, he must have had a strenuous voyage. On starting he sent to her one of his pretty little letters:-- (_Lord Dufferin to Miss Nightingale._) S.S. "TASMANIA," _Nov._ 13 [1884]. MY DEAR MISS NIGHTINGALE--I duly received the papers you were good enough to send me, and you may be quite sure of my studying them with the attention they deserve. I well know how well entitled you are to speak with authority in reference to Indian questions, and I can well believe that you have thought out many conclusions which it would be of the greatest benefit to me to ponder over. I hope you will forgive me for adding that one of the pleasantest "sweets of office" I have yet tasted has been the privilege I acquired of coming to pay you that little visit. [210] They were ultimately passed with some amendment by Lord Ripon's successor.
