ANIMAL DISEASES 
thought, which has occurred to me, is that many 
surgical procedures developed for the treatment 
of congenital heart disease in man are done in 
normal animals. It would be very nice indeed for 
cardiac surgeons and others involved in this area 
to have truly anatomical replicas of what it is 
they're trying to correct, not only to develop the 
operations, but to test their efficacy.
