The left os innominatum was perfectly free from any 
unnatural appearance in every part, even to its junction 
at the fymphyfis of the pubis', but there the line was 
drawn, and difeafe immediately began to fhew itfelf 
through the whole of the right os innominatum , and to 
advance as it were from a fuperficial ulceration to ex- 
crefcences in the greatell: quantity. 
It is remarkable, that the cartilage connecting the 
ojja pubis fhould be fo complete a boundary to the 
difeafe; for though the external lamella was in all that 
part of the os pubis and ifchium (particularly at the ramus 
of the latter) which united forms the foramen ovale , not 
the leaft deficiency is to be obferved in the left os pubis. 
So interefting to the knowledge of the nature of this 
difeafe is it to obferve that the extent of the tumor, which 
terminated exactly at this part, Ihould likewife as exactly 
have limited its effects or confequences. ~ . r 
So far then as the external lamella of the os pubis 
and ifchium was deficient, fo far thefe bones prefented: 
that roughnefs and irregular lofs of fubftances which is 
commonly denominated ulceration or fuperficial caries. 
The bottom of the acetabulum had likewife fuffered in a 
fimilar manner: but over the whole of the ilium, both 
externally and internally, the lamella feemed very little 
injured, though covered by vaft quantities of boney
