MICROSCOPIE IN GERMANY. 
to the left, the incisor teeth bore heavily on the chest in the 
region of the heart; his respiration was labored, the cervical 
muscles grew lax, and thus lie continued for perhaps ten minutes. 
Finally he stretched his nose out to the greatest limit, struggled 
once or twice, and was dead. The post mortem made eighteen 
hours after death revealed no disease of other organs than the 
heart and stomach. 
The former looked hypertrophied, but I did not weigh it. 
Both ventricles contained large amounts of clotted blood. When 
washed, the endocardium of both ventricles was striped as if 
painted, with bands of eccliymosis as wide as one of the lingers, 
from above downward, the spaces between being of a natural color. 
The valves were also blackened. Pericardium was apparently 
free from traces of disease. 
The peritoneal covering of the stomach was torn in a direction 
legnthwise with the stomach for about fourteen inches. There 
CJ 
was an aperture through the muscular coats of the stomach as 
large as a silver dollar, midway between the greater and lesser 
curvatures, and about equally distant from the orifices. 
DEVELOPMENT AND PRESENT STAND OF MICRO¬ 
SCOPIE IN GERMANY, 
By a Lady Friend of the “ Review.” 
(Continued f rom page 227.) 
Up to the present time most of the improvements in the com¬ 
pound microscope had been made in foreign lands, and it was , 
owing to their introduction into Germany that the German micro¬ 
scope has attained its present excellence. The most considerable 
improvement in the compound microscope was made by Hertel in 
the eighteenth century. He introduced reflected light through a 
mirror, and changed the microscope which up to this time had 
been horizontal, into a vertical one. 
It is a matter of surprise that twenty years should pass before 
these excellent improvements should come into general use. 
Hertel’s microscope was better than any that had preceded it in
