Receding from the centre, the tissue increased in density, 
becoming more difficult to cut, and irregular edges of the 
softened bones were found under the scalpel, which might be 
considered as forming the transition between the alterations 
and the bonv tissue. 
The tumour, which obstructed the superior third of the 
nasal cavity, was a pedunculated one, adhering to the 
bony substance of the inferior turbinated bone. This surface 
of attachment was of an elliptic shape, the greatest diameter 
of which was six centimetres in length, and the smallest from 
two to three. The corresponding bony substance presented 
a greater density, particularly as compared with that of the 
other portion of the same bone. The mucous membrane 
formed an elevation round the root of the tumour, and was 
much injected. There were also numerous ulcers on its surface, 
but they were small and shallow, and of a white appearance. 
The polypus formed a mass weighing altogether 500 grammes. 
It was very dense, particularly towards the root. The sec¬ 
tion discovered a mixture of a white and gray substance, 
of a fibrous nature ; however, microscopic examination 
showed that it was composed of epithelial scales, the agglo¬ 
meration of which gave it this fibrous appearance. The 
tumour was not covered by the mucous membrane of the 
nasal cavity, which must have been ruptured by the disten¬ 
sion of it through the development of the polypus in the sub¬ 
mucous cellular tissue, which would explain the elevation of 
the mucous membrane around the root of the tumour. 
These were the lesions which were found by the author in 
this extraordinary case. At first, by their complexity, they 
would lead to the supposition of two distinct affections, viz., 
a polypus and osteo-sarcoma of the maxillary bone, but the 
microscopic examination which Mons. Aubenas was kind 
enough to make showed that the polypous tumour and the 
alteration of the osseous structure were the results of one and 
the same cause.
