was obtained from living and adult animals. ‘The measurements of 
the nuclei were taken after their exposure, by the aid of dilute acetic 
acid on the corpuscles, which it is necessary to state, since I have 
elsewhere* shown that the form and dimensions of the’ nucleus are 
materially affected by different treatment.

4000 corpuscles is about twice that of 
3555 the corpuscles of the mother. The 
3200 corpuscles of the foetus contained 
distinct nuclei, much resembling 
sa lymph globules. The size only of 
2666 the nucleated corpuscles is above 
609 given ; there were several much 
smaller which presented no nuclei.
