EDITORIAL OBSERVATIONS. 
Who can set limits to onward progress — who can curb the 
Pegasus of science ? 
Mr. Morton notices, as instances of improvement, the 
diminished employment of venesection in our treatment of 
disease ; the substitute of the mylabris for the cantharis as a 
vesicatory; the advantages of the sandal, &c. &c. 
Professor Morton concludes his admirable — we may say 
friendly address to his young class, with the following well 
selected observations, to be retained and treasured up in 
minds — sanguine and ardent of success in their professional 
career : 
“The profession chosen by you, if rightly followed, is one 
that exalts man, and renders him esteemed by the right- 
thinking and the wise, because it contributes to the relief of 
the sufferings of those animals which, although placed lower 
in the scale of creation than man, equally with him constitute 
a part of the great chain, from which 
“ * whatever link you strike, 
Tenth or ten-thousandth breaks the chain alike.’ 
“ 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 not, 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 : 
but 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.’ ”
