i got it from the school of tropical medicine in london. feed from me, it's a very slow feeder. and so i could follow the whole process of this insect in me, what happens. and the first time it had its mealfrom me — all these insects, just before they take their blood from you, they put in a tiny bit of their own saliva, this is what causes the trouble. anyway, the first bite that it had from me — no response at all. and that's what one would expect, because i ‘d never met it before. second bite, yes, a delayed response. and that got more and more, larger and larger every week, until my arm was, on the fifth bite, swollen for three days from the bite. and so by the eighth bite the question was, i was hoping i might be desensitised and nothing would happen, but to be absolutely certain i went into the side ward of the hospital to see what happened. it produced, i remember taking the cotton ball out, it ran down the test tube and began its meal. and then five or six minutes, the nurse who was my blood pressure said "the machine is broken". an
