Mr dear Sir

I have taken out the enclosed figures from the set of Bills of Mortality in the British Museum. I do not know how it happened that I omitted them in my book[.]

Whooping-cough holds a somewhat peculiar place among the so-called Zynotic Diseases. As a cause of death It is now very [2] prominent (of course for infancy only), owing to the great reduction of other causes. But this is an epidemiological principle which may not perhaps come into the scope of your inquiry.

I remain, dear Sir | yours faithfully | C. Creighton¹ [signature]
