MR. BARLOW’S LETTER. 
I presume your choice has been deliberately made. Con- 
siderate reflection has convinced you of its suitability to 
your faculties, inclinations, and mental powers. You have 
weighed its advantages and disadvantages, and have hot, I 
trust, been lured by a love of ease, or those prismatic illusions 
which a vivid imagination too often presents to the mind of 
youth ; but each of you is contented to become a labourer in 
the field of science, and to co-operate with those who strive 
to develope its truths, and render them practically useful to 
mankind. Let nothing, then, cause you to relax in your 
determinations, nor interfere with your studies ; neither 
indulge in those deviations which too often lead to excess : 
and may the incentive of the poet to increased and sustained 
industry be yours : — 
“ Deeper, deeper will we toil 
In the mines of knowledge ; ; 
Nature’s wealth and learning’s spoil 
Win from school and college : 
Delve we there for richer gems 
Than the stars of diadems. 
“ Onward, onward will we press 
In the path of duty ; 
Virtue is true happiness. 
Excellence true beauty : 
Minds are of celestial birth, 
Make we them a heaven of earth.”

Dear Sir. — Mr. Mayhew^s letter in your last reminds me 
forcibly of his wonderful story regarding the heart, which 
appeared in ‘ The Veterinarian 9 some months ago. Both per- 
formances are matchless for reckless assumption, and as 
showing the wild vagaries committed by a morbid fancy. In 
your October number he has made statements along with 
insinuations, and has given interpretations of assumed facts 
in regard to myself and a Review, which are incorrect and 
unjust throughout. They are utterly erroneous from end to 
end, and are grounded on a false supposition that I am editor 
of a certain paper. I beg once, and for all, to] inform Mr. 
Mayhew, and his veracious informant (if such an one there 
be beyond his own imagination), that I am not Editor of
