OF THE BLOOD.

are commonly slightly larger than when they are slowly dried, or than 

 when they have been swimming for a few minutes either in the liquor 

 sanguinis, in the serum, or in dilute watery solutions of neutral salts. 

 On the contrary, the red corpuscles of birds and reptiles are usually 

 rather smaller in the dried state, however quickly it may have been done, 

 than in the fluid blood. The chyle-corpuscles were obtained from the 

 thoracic duct while digestion was active; and the lymph-corpuscles 

 from the lymphatic glands, except when stated to the contrary. 



The measurements are all made in vulgar fractions of an English 

 inch ; but, for the sake of convenience, the numerator, being in- 

 variably 1, is omitted throughout, and the denominators only are 

 printed. The corpuscles were all measured as they appeared flat on 

 the object-plate, unless when a T indicates a measurement of their 

 thickness. By L. D. their long diameter, and by S. D. their short 

 diameter is denoted. 



Remarks on the shape or size of the blood-corpuscles are contained 

 in Notes xcv, xcvin, cv, cxvi, cxvn ; and on the corpuscles of chyle 

 and lymph, in Note cxxn.
