Another paper, by Dr. Barker, entitled “Continuous Creation versus Dar- 
winian Evolution,” evidently the result of much reading and thought, naturally 
excited a good deal of discussion, as it treats of a subject of the deepest 
interest, which at present engages the attention of some of the profoundest 
thinkers of the day. 
- Whatever opinion may be formed of the theory propounded by Mr. 
Darwin, most persons will agree that science is indebted to him for the facts 
which he has collected, and for the great amount of information which he 
brings to bear upon his subject, as well as for his candour and fairness in 
stating and supporting his views. 
We must always bear in mind that two classes of workers are necessary 
for the advancement of science, namely, those who collect facts and those who 
deduce general conclusions from those facts. It has often been said that fact 
is worth more than theory, and it is of course true that the value of theory 
depends on the extent to which it is founded on fact—but both have important 
uses in the elucidation of truth. An ingenious theory, though not altogether 
sound, may be the means of attracting and setting to work minds of different 
schools of thought, and by the help of the light thus let in from various 
sources, truths may be arrived at which otherwise might have remained long 
undiscovered. To quote the eloquent language of Sir John Herschel, in his 
“ Introduction to the Outlines of Astronomy,” “ No grand practical result of 
human industry, genius, or meditation, has sprung forth entire and complete 
from the master hand or mind of an individual designer, working straight to 
its object, and foreseeing and providing for all details. As in the building of a 
great city, so in every such project the historian has to record rude beginnings, 
circuitous and inadequate plans, frequent demolition, renewal, and rectification, 
the perpetual removal of much cumbrous and unsightly material and scaffold- 
ing, and constant opening out of wider and grander conceptions, till at length 
a unity and a nobility is Miine, little dreamed of in the imagination of the 
first projector. . * No man can rise from ignorance to 
anything deserving to be called a complete grasp of any considerable branch of 
science without receiving and discarding in succession many crude and incom- 
plete notions, which so far from injuring the truth in its ultimate reception, 
act as positive aids to its attainment by acquainting him with the symptoms 
of an insecure footing in his progress. To reach from the plain the loftiest 
summits of an alpine country many inferior eminences have to be scaled and 
relinquished ; but the labour is not lost. The region is unfolded in its closer 
recesses, and the grand panorama which opens from aloft is all the better 
understood and the more enjoyed for the very misconception in detail which it
