nation was claimed to be that of any animal, whose corpuscles 
are much smaller than those of man, and where the corpuscles 
found, as the result of such examination, were as large as the 
human. 
I object to the word “ restore,” as used by this writer. If 
he means by it that as the result of his manipulations, shrunken 
blood corpuscles are brought back to their original size in a 
given case, how can he say what their original size should be; 
or that by his enlarging process he does not carry them beyond 
their original or normal size? 
_Itis only from the fact that dried blood corpuscles do not 
undergo change of form or size in our manipulations with 
reference to measurement, that we can claim in any manner, to 
separate the corpuscles of one animal from that of another. It 
would seem further, that by the use of the term “ roundest,” by 
this author, in connection with the description of his *‘ restoring ” 
process, that he intended to convey the idea, that by this process, 
(like as by the action of certain reagents upon fresh blood), he 
was capable of changing the disc-like form of the dried blood 
corpuscle to the globular form. Or rather, perhaps, he means 
by “select the roundest,” on page 213, that we should select the 
“ circularest ” (Mr. Weller?) or those nearest to a circular form. 
On page 214, which follows this description of “ restoring ” blood 
corpuscles, which I did not notice until the above was written, 
he says: 
‘“The human corpuscle will expand to the rupturing point and 
collapse much sooner than will that of a dog, when treated precisely 
alike.” 
This fully justifies all that I have said above. 
If the human corpuscle wiil (for this is the state in which 
they are presented to us for examination in legal trials,) “ ex- 
pand to the rupturing point” by any process of “ restoration ” 
there must be a time in this expanding process when the 
corpuscle has not reached this point. It might be well to inquire 
at what time, while this process is going on, the corpuscle 
becomes of its normal size, and how we are to determine, when 
and where this point is reached? And further, we might ask, 
as to how, after this point is ascertained, we shall stop the 
process of expansion so as to measure the said corpuscles? I 
close by saying, that it seems fully evident to my mind that all
