Hematology of the common Indian Frog Rana tigrina. II. Leucocytes.

A study extending over a period of two years has been made on Leucocytes differential count in common Indian frog R. tigrina. As the values of differential count are almost similar in males and females, the data obtained for the two sexes have been pooled together. A table is given to compare the values of different Leucocytes in R. tigrina with the values reported in other species of Rana. The month to month variation has been recorded in various counts and an inverse relationship is observed in the number of Lymphocytes and Neutrophils in different months of the year.
