After injecting with starch-mass through the right femoral vein it was found that the entire arterial system of the cat was filled with starch. Investigation showed the presence of good sized functional ductus venosus through which the arterial and venous systems communicated. The individual possessing this peculiarity was, in life, troubled with what is vulgarly called "fits," whatever that may have been in this particular case. I should be loath to admit any relation between "fits" and the presence of a functional ductus venosus without more extended data.
