D. P. YONRERMAN. 
pert be guided by this rule it seems to me that expert evidence 
will be far from the worthless tiling that some would affect to re¬ 
gard it. Always bear in mind that the truth is the object of all 
legal inquiry. In all expert evidence the witness must never for 
a moment transgress the limits of scientific accuracy nor with the 
warmth of a partisan, or the desire to do the best he can for his 
case, permits himself to color or distort, directly or indirectly, the 
hard, straight and inflexible lines of well attested scientific facts 
such as he would never dream of disputing, coloring or distorting 
before a learned society. 
A witness must not quote authorities in the witness-box, 
although there is sometimes a great temptation to do so. But he 
must remember that he is called to give his opinion and not to 
say who agrees or disagrees with him. No written or published 
opinion of a living authority can be quoted even by counsel, the 
law requiring that if the opinion of such authority be deemed 
necessary in the judgment of those conducting the case, the 
authority himself should be called to state his opinion on oath and 
be subject to cross-examination. 
And here I want to give you a word of practical advice. If 
a quotation from the works of a deceased authority is read to you 
in cross-examination, and you are asked how far you agree or 
disagree with the opinion expressed, never under any circum¬ 
stances accept the quotation as expressing the opinion of the au¬ 
thority in question; neither assent to nor dissent from the quota¬ 
tion until you have asked to be permitted to see the book from 
which the quotation is made, for a counsel may misrepresent the 
author wilfully or by mistake, as one sentence preceding or 
following the quotation read will often put an entirely new aspect 
on the quotation itself.
