999, THE MIcROSCOPE. 
the important propositions in this paper are obnoxious to like 
criticism, and that the motto at the head of my communication 
may well apply to them. 
It certainly seems to me that if in legal tribunals testimony 
based upon such so-called scientific investigation as this should 
be received as evidence, that such a state of things would be 
fraught with grave danger, as it regards the ends of justice, and 
also to the reputation of those so-called scientists, who should 
so testify: “*The human red corpuscles willaverage much larger 
than those of any dog.” (Dr. Thad 8. Up De Graff, in The 
Microscope, and its relation to Medicine and Science, etc., Dec. 
1883, page 214.) 
In reply I give the following table, premising it with the 
remark that Drs. Woodward, Richardson, Treadwell, and many 
others, together with the French, German and English Observ- 
ers in this field, as far as I am informed, agree with the conclu- 
sion thus set forth in my table:

This table was made from the blood of puppies of different 
ages, varying from a few days to several weeks. I have found 
in a few cases the blood corpuscles of adult dogs, corresponding 
in size with the above. I adda table made from the blood of 
three infants: The first, two weeks; the second, one day; the 
third, two days old:
