William Horton Lloj-d, Esq., in the Chair. 



A communication was read from George Gulliver, Esq., F.R.S. 

 &c., containing additional measurements of the Blood-corpuscles of 

 Mammalia and Birds. No. 3.* 



The measurements, as in all my former ones of the blood-corpuscles, 

 refer exclusively, unless othervvise mentioned, to the red particles or 

 discs. The diameters, as usual, are given in vulgar fractions of an 

 English inch; and as the numerator is always 1, it is left out, the 

 denominators only being printed. Other particulars are explained 

 at the head of my former Communications.

I do not know that the blood- 

 discs of any -vvhale have been 

 before measured. They are, likę 

 those of the porpoise, of the com- 

 mon circular form. Those of the 

 ■tt-hale are but slightly larger than 

 the human blood-corpuscles, and 

 decidedly smaller than those of 

 the elephant and sloth. 



The measurements were made 



from some rather imperfect spe- 

 cimens of the dried corpuscles, for 

 ■which I am indebted to that ex- 

 cellent anatomist Mr. J. Quekett.

 Blood from a prick of the lip 

 and from a vein of the ear of a 

 fine adult malė. The corpuscles 

 are smaller than those of the 

 mouflon and of the common sheep, 

 being most nearly allied in mi- 

 nuteness to the corpuscles of the
