• anesthetic (none, for part of experiment, or 
entire experiment) [3]; 
• types of vertebrates (mammals— rodents, rab- 
bits, primates, carnivores, ungulates, and 
others— birds, reptiles, amphibians, and fish) 
[16); 
• neoplasia [4]; 
• infection and immunology [4]; 
• primary purpose (to study body function or 
structure, to develop or study the various 
products or chemicals, to develop transplant 
techniques) [15]; 
• toxicity tests [61; 
• experiments in response to domestic or for- 
eign legislation [14); and 
• use of particular painful techniques (such as 
eye irritation) [14]. 
These annual reports are compiled in detailed 
reports. Several tables from the 1984 report are 
included here. Table 16-3 shows the frequency 
with which various species are used in the United 
Kingdom, table 16-4 shows the primary purpose 
of the experiments, and table 16-5 shows the reg- 
istered institutions performing experiments. These 
tables represent only highlights of the consider- 
able data available.
