A GRAPHICAL STUDY OF THE BLOOD OF NORMAL FOXES
The fluctuations and trends of various cellular elements of normal fox blood are presented in graphical form. The graphs have been prepared from data obtained from a number of foxes of various ages and show the minimum, maximum and mean numbers of blood elements occurring in both males and females in each age group.The red blood cells, haemoglobin, and to a lesser extent the neutrophiles, on the one hand, have trends of a similar nature and appear to be related. On the other hand the total white blood cells, lymphocytes, monocytes and basophiles also appear to be closely related. A comprehensive picture of the field tends to divide the numbers of blood elements composing the blood of foxes into these two divisions.The trends and fluctuations, for the same age groups, of the total white blood cells and lymphocytes are almost identical. The monocytes and basophiles also show close similarity. A close similarity in general trend, with less marked fluctuations, exists in the four groups, total white blood cells, lymphocytes, monocytes and basophiles.
