EXPLANATION OF PLATE 31, 
Illustrating Mr. Gr. H. Drew’s paper on “ Some Points in the 
Physiology of Lamellibrauch Blood-Corpuscles.” 
Fig. 1. — Finely gi’anular eosinophil corpuscles in expansion and con- 
traction. Stained with eosin and methylene blue. X 750. 
Fig. 2. — Coarsely granular eosinophil corpuscles in expansion and 
conti'action. Stained with eosin and methylene blue. X 750. 
Fig. 3. — Basophil corpuscles in expansion and contraction. Stained 
with methylene blue. X 750. 
Fig. 4. — Agglutinated masses of corpiiscles adherent to strands of 
cotton fibre, showing thin coimecting bands of protoplasm, x 100. 
Fig. 5. — Later stage of fig. 4, showing thickening and contraction of 
the connecting bands of protoplasm. The cotton fibres have been 
drawn closer together by the contraction, x 100. 
Fig. 6. — Ingested bacteria in the corpuscles. X 750.
