Abstract
I HAVE handed to Prof. Judd the specimens of “blood-rain” dust collected by me in Sicily, as mentioned in your issue of March 28. It may be remembered that the dust was collected from three tables on the terrace of the hotel, and that I brought home that from the most favourably situated table in the wet state in which it was obtained. This has since been dried and weighed, with the result that, as I expected, the density of the fall was greatest on this table, being equivalent to 91/4 tons per square mile. The average given by the other two tables was 51/2 tons per square mile.
