Sir Everard Home on the changes, 
Fig. 5. Three days after being spawned. At this period 
muscular motion is for the first time perceptible. The letter 
D shows the ovum laid open on one side ; magnified ten 
times, as in letter C. 
Fig. 6. Four days after being spawned. The letters cor- 
respond to these in Fig. 5. 
Plate VII. 
Fig. 1. Five days after being spawned. At this period the 
ova become separated, and the tadpoles begin to leave the 
ovum. A. Shows a tadpole in the act of extricating itself ; 
magnified five diameters. 
B. A back view of it ; magnified eight diameters. 
C. A belly view. 
D. A side view. 
E. A longitudinal section ; all the views magnified eight 
diameters. 
Fig. 2. Six days after being spawned, four different views ; 
magnified eight diameters, as in Fig. 1. 
Fig. 3. Eight days after being spawned ; all the views 
magnified eight diameters. 
Fig. 4. Twelve days after being spawned ; four views of 
the tadpole ; magnified eight diameters. 
The animal in twelve days had become so far advanced in 
its growth to make further progress in the investigation 
unnecessary, after the splendid figures that are before the 
public upon that subject in different publications.
