So Ross and Mr. Mahomed Bux set to work to try to find once more the black-dotted circles in the stomachs of mosquitoes. Mr. Mahomed Bux sleuth-footed it about, among the sewers, the drains, the stinking tanks of Calcutta, catching gray mosquitoes and brindled mosquitoes and brown and green dappled-winged ones. They tried all kinds of mosquitoes (within the limits of Ronald Ross’s feeble knowledge of the existing kinds). And Mr. Mahomed Bux? He was a howling success. The mosquitoes seemed to like him, they would bite Hindus for this wizard of a Mahomed when Ross could not make them bite at all--Mahomed whispered things to his mosquitoes.... And a rascal? No. Mr. Mahomed Bux had just one little weakness--he faithfully got thoroughly drunk once a week on _Ganja_. But the experiments? They turned out as miserably as Mahomed turned out beautifully, and it was easy for Ross to wonder whether the heat was causing him to see things last year at Begumpett. Then the God of Gropers came to help Ronald Ross. Birds have malaria. The malaria microbe of birds looks very like the malaria microbe of men. Why not try birds? So Mr. Mahomed Bux went forth once more and cunningly snared live sparrows and larks and crows. They put them in cages, on beds, with mosquito bar over the cages, and Mahomed slept, with one eye open, on the floor between the beds to keep away the cats. On St. Patrick’s day of the year 1898, Ronald Ross let loose ten gray mosquitoes into a cage containing three larks, and the blood of those larks teemed with the germs of malaria. The ten mosquitoes bit those larks, and filled themselves with lark’s blood. Three days later Ronald Ross could shout: “The microbe of the malaria of birds grows in the wall of the stomach of the gray mosquito--just as the human microbe grew in the wall of the stomach of the brown spot-winged mosquito.” Then he wrote to Patrick Manson. This lunatic Ross became for a moment himself a malaria microbe! That night he wrote these strange words to Patrick Manson: “I find that I exist constantly in three out of four mosquitoes fed on bird-malaria parasites, and that I increase regularly in size from about a seven-thousandth of an inch after about thirty hours to about one seven-hundredth of an inch after about eighty-five hours.... I find myself in large numbers in about one out of two mosquitoes fed on two crows with blood parasites....” He thought he was himself a circle with those jet-black dots.... “What an ass I have been not to follow your advice before and work with birds!” Ross wrote to Manson. Heaven knows what Ronald Ross would have discovered without that persistent Patrick Manson. You would think that such a man as Ross, wild as the maddest of hatters, topsy-turvy as the dream of a hasheesh-eater, you would swear, I say, that he could do no accurate experiments. Wrong! For presently he was up to his ears in an experiment Pasteur would have been proud to do.
