from the instrument, whilst witli the one eye he looks at the object, and with the 

 other draws the figure. A very little reflection will convince anyone how unde- 

 sirable it is not to keep the nerves of the eye as nearly in their right position as 

 possible. An undue strain is caused if they are strained, and the sight is injured 

 if much work is done. Let us all, young and old microscopists, be very sceptical 

 at times as to what we think we see with the very highest powers. Without 

 wishing to detract an iota from the honesty of purpose and truth of my fellow- 

 students, I am sure that a good deal unintentionally has been said to have been 

 seen with the miscroscope which has never been seen at all. We set to work 

 longing to discover something newer than the last new thing. We hope to find it, 

 we begin to think we have found it, and we may go so far as to make ourselves 

 believe we verily did see it once. The event must be recorded ; we proclaim it, 

 and in so doing propagate error. The microscope, like the photographic 

 apparatus, has its defects. Let us enjoy seeing what glories there are in it, and 

 without hesitation use it for the best and purest purposes.
