6. The first reports of hematopoietic neoplasms in reptiles 
[Cowan, D. F. J. Amer. Vet. Med. Assoc., 153 : 848-859, 
1968; Frank, W. & A. Schepky. Pathol. Vet., (i: 437-443, 
1969]. 
7. The only C-type virus in lower animals was discovered 
in a viper [Zeigel, R. F. & H. F. Clark. J. Natl. Cancer 
Inst., 43_: 1097-1102; 1969] and DNA polymerase activity 
is associated with this RNA virus [Hatanaka, M. e_t a 1 . 
Proc. Natl. Acad. Sci. USA, 67: 143-147; 1970]. 
8. Experimental studies on the epizootic hematopoietic 
neoplasms in northern pike (RTLA 112) and muskellunge 
(RTLA 808) suggests a viral etiology. 
9. Transplantable hematopoietic neoplasms in a Mexican 
axolotl (RTLA 506). 
10. Transplantable invasive neuroblastomas and imaginal 
disk neoplasms in insects (RTLA 381-383). 
11. Epizootic hematopoietic neoplasms in various oysters 
and mussels involving two cell types (RTLA 224, 225, 
235, 502). 
12. Papillomas and carcinomas in bullheads from selected 
Florida lakes (RTLA 288, 289, and numerous others in 
the collection). 
13. Papillomas in several populations of Australian 
oysters (RTLA 107, 151, 160-162, 215, 223). 
14. Discovery of a herpes virus in an oyster [Farley, 
C. A., W. G. Banfield, G. Kasnic, Jr., & W. S. 
Foster. Science, 178 : 659-760; 1972], 
15. The first discovery of adenomatous polyps of 
gastric mucosa in cold-blooded animals (RTLA 570, 
571). These tumors were found in trout which also 
had hepatomas. Aflatoxin was absent from the diet 
so some other carcinogen must have been involved. 
16. Papillomas (RTLA 550-553) and an ameloblastic odontoma 
(RTLA 675) in cunners. 
17. The first smooth muscle neoplasm (leiomyosarcoma) 
in a reptile (RTLA 560). 
18. Epizootic skin neoplasms in neotenic tiger 
salamanders in a sewage settling pond (RTLA 791, 
792) .
