Sir Everard Home on the structure , &c. 
EXPLANATION OF PLATE II. 
It represents muscular fibres magnified in different 
degrees. 
Fig. 1. A fasciculus of fibres taken from the bullock’s neck, 
sufficiently dissected to show the separate fibres ; magnified 
100 diameters. 
Fig. 2. A portion of the same fasciculus, the fibres more 
unravelled ; magnified 200 diameters. 
Fig. 3. A portion of a fibre in its contracted state, con- 
sisting of five blood globules, and exactly one inch in length, 
taken from the bullock’s neck ; magnified 400 diameters. 
Fig. 4. The same length of fibre extended to its utmost, 
without giving way ; magnified 400 diameters. 
The calf was selected for this last purpose, the elastic 
medium between the globules being less brittle in the young 
than the full grown animal.
