Roe-deer frequently bear twin fawns. My own observations in Northumberland during the past twenty years, however, led me at first to believe that single fawns were more usual in this part of the country. I was rather surprised, therefore, to learn that the Hancock Museum in Newcastle upon Tyne had received a number of roe fœtuses, during the early months of the past three years, all of which proved to be twins, in each case a male and a female.
