LECTURES, 25 
was not pleasant to hear that the germs of tetanus are so plentifully to 
be found in haystacks, or in the cobwebs with which the unwary 
sometimes poison the wounds which they try to stanch. Finally the 
lecturer gave some explanation of the process by which these deadly 
microbes kill us or are defeated in their attempt, and mentioned a 
theory which is now attracting some attention, though it cannot yet be 
said to be proved. ‘This is, that of the two kinds of corpuscules red 
and white, of which our blood is composed, the red is that on which 
the microbe preys, while the white is our defender, ever ready to 
enclose and kill and cast away the deadly enemy which attacks the 
frame, and that like any other soldier it may be drilled and disciplined 
by proper training to higher efficiency in coping with its foe. At the 
conclusion of the lecture the Principal thanked Mr. Shenstone for 
one of the most interesting lectures ever given to the Society, and in 
this feeling we are sure that all who heard it will cordially agree.
