PROSTATE. 
What are the lesions of the prostate ? 
Tt may be hypertrophied from senile changes. The hypertrophy 
is due to an increase of muscular or glandular elements. The 
prostate may be atrophied as a result of injury or inflammation. The 
inflammation may be caused by gonorrheeal infection or by injuries, and 
may be of the acute exudative or of the chronic productive variety. 
The prostate also may be the seat of a tubercular inflammation. 
What tumors have been found in the prostate ?

THE BONES. 
Name the different classes of inflammation affecting bones. 
Pervostitis, affecting the periosteum. 
Osteitis, affecting the bony tissue. 
Osteomyelitis, affecting the marrow and bony tissue. 
Name the varieties of periostitis. 
Simple acute periostitis. 
Suppurative periostitis 
Fibrous periostitis. 
Ossifying periostitis. 
Tubercular and syphilitic periostitis. 
Describe simple acute and suppurative periostitis. 
In the simple acute form the periosteum is thickened, congested and 
mere or less infiltrated with leucocytes and serum, the connective-tissue 
fibres are swollen. The periosteum becomes more or less firmly 
adherent to the bone, and in the inner layer the cells are increased in 
number. This may terminate by resolution or may continue as a sup- 
purative inflammation. This form may begin as a purulent process. 
There may be a collection of pus between the periosteum and bone, or 
in the periosteum itself. The affected parts may break down and 
become gangrenous, or the pus may be absorbed or become dry or
