DISCUSSION 
Questioner (unidentified) : What kinds of 
research and development does your laboratory 
do? 
Dr. Wallin : A variety of research programs 
and contractual obligations ranging from the 
development of heart valves and membrane ox- 
ygenators to a variety of cardiac assist devices 
and total heart replacements. 
J. R. Held, NIH : You talked about the disad- 
vantage of the growth of calves which is one 
that we all recognize, and also you just touched 
on the subject of sheep. I wonder why you 
wouldn't consider sheep or goats as perhaps a 
more appropriate animal because of this. 
Dr. Wallin : We've had difficulty, I think as 
others have expressed, in getting sheep large 
enough for some of our studies. I think we've 
found, for many of our studies, animals in the 
250 to 300+ range have been most desirable,
