[105] The other day in a bookseller's catalogue of "Association Books" I found this item: "Florence Nightingale's _Notes on Lying-in Institutions_. Presentation copy, with autograph inscription, 'To His Excellency the Lord Napier, Madras, this little book, though on a most unsavoury subject, yet one which, entering into His Excellency's plans for the good of those under his enlightened rule, is not foreign to his thoughts--is offered by Florence Nightingale, London, Oct. 10, '71.'" A subject on which Miss Nightingale wrote both to Lord Napier and to Lord Mayo was the inquiry into cholera in India ordered by the Secretary of State in April 1869. She had made the proposition many months before. Indian medical officers were absorbed in propounding theories; Miss Nightingale wanted first an exhaustive inquiry into the facts. Even if such an inquiry did not establish any of the rival theories, it must lead, she thought, to much sanitary improvement. Sir Bartle Frere strongly supported the idea, and it was arranged that the War Office Sanitary Committee should make the suggestion and elaborate the scheme of procedure to be followed in India. The Committee meant for such a purpose Dr. Sutherland, and Dr. Sutherland meant in part Miss Nightingale. Sir Bartle Frere constantly wrote to her to know when the India Office might expect the Instructions, and Miss Nightingale as constantly applied the spur to Dr. Sutherland. On April 3 she delivered an ultimatum: "Unless the Cholera Instructions are sent to me to-day, I renounce work and go away." At last they arrived, and her friend received a withering note: "_April_ 13, 1869. I beg leave to remark that I found a letter of yours this morning dated early in Dec., which I mean to show you, in which, with the strongest objurgations of me, you told me that you could not come because you intended to get the Cholera Instructions through by _December_ 12, 1868. My dear soul, really Sir B. Frere could not have known the exhausting labour he has put you all to; to produce that in four months must prove fatal to all your constitutions! He is an ogre." Dr. Sutherland's Instructions are admirably exhaustive, and may well have taken some time to prepare. The remaining stages of the affair were quick, and the Secretary of State's dispatch went out to the Government of India on April 23, followed by private letters from Miss Nightingale. The Sanitary Blue-books of successive years contain copious reports and discussions upon this "Special Cholera Inquiry." It furnished much material for scientific discussion, by which Miss Nightingale sometimes feared that what she regarded as the essence of the matter was in danger of being overlaid. She and the Army Sanitary Committee took occasion more than once to point out that "whatever may be the origin of cholera, or whatever may ultimately be found to be its laws of movement, there is nothing in any
