More often that which is transmitted from parent to offspring is a predisposition to the disease, the activity of which is augmented by exposure to infective conditions. An instance of congenital tuberculosis in the calf was recently reported by Ravenel, to the Pathologic Society of Philadelphia, and specimens from a further example of the same kind were exhibited by MacFadyen at a late meeting of the Pathological Society of London. As a rule the calves of tuberculous cows are born free from tuberculosis, and fetid infection is usually, if not always, associated with tuberculosis of the placenta or of the uterus. Dissemination takes place under these circumstances through the blood-stream, as indicated by the wide-spread and discrete distribution of the lesions.
