It seems peculiar that glomerular capillary 
endothelial swelling has not been previously re- 
ported in an animal, particularly since research 
on non-human primates has increased so mark- 
edly in the last decade. The reversible character 
of the lesion is undoubtedly partially responsi- 
ble, along vi^ith the fact that good fixation and 
thin microscopic sections are necessary to ade- 
quately delineate the pathological changes. 
There appears to be no logical reason to assume 
that pre-eclampsia is confined to the human 
race. Percutaneous renal biopsies during the 
late stages of pregnancy in chimpar-^^^es and 
other non-human primates might v^^ell uncover 
additional examples of this disease. 
Essential Hypertension 
Although hypertension can be induced exper- 
imentally by a variety of methods in several 
species, there is at present no spontaneous or 
experimental animal model for essential hyper- 
tension in humans. We v^ere pleasantly sur- 
prised to discover cardiovascular changes sug- 
gesting essential hypertension in a chimpanzee.
