Oh! my goodness! there was the prettiest little Easter daisy in the world, and flitting about it was a charming microscopical gnat.
He took a strong infusion of common cress, placed it in a flask, boiled it, and, while boiling, hermetically sealed it. He then heated it up in a digester to 270° F. It was kept for nine weeks and then opened, and, in his own language, on microscopical examination of the earliest drop "there appeared more than a dozen very active monads." He has fortunately measured and roughly drawn these.
Most of these had been seen by Harry and Philip many times before, so that Fred had a very long inspection of the microscopical wonders, and was greatly puzzled to understand how many hundreds of times any little object could be magnified; and, on afterwards looking beside the microscope at the speck upon the glass plate, which, when he looked through the instrument, had appeared to be of the most gorgeous tints, he could scarcely believe that both objects were the same; and he kept taking his eye from the instrument to look down the side, and then, with a wondering air, back again.
Of course the full force of this idea could only be appreciated in the light of later knowledge; but even at the time of its coming it sufficed to give a great impetus to that new medical knowledge, based on microscopical studies, which had but recently been made accessible by the inventions of the lens-makers.
The selection of material for the experiments planned, the watching and cultivating of the living forms in the laboratory tanks, the cutting of numberless filmy sections for microscopical examination these things, variously modified for each case, make up the work of the laboratory student of general biology.
Passing to speak of the microscopical character of the contents of the bowel, Dr. Koch said that owing to the sanguinolent and putrescent character of these in the cases first examined, no conclusion was arrived at for some time.
She learned to watch herself carefully, and when with him to preserve a discreet attitude that should not offend him. No curious looks, and no questions. But this was not always easy, so she asked leave to assist him in his work, and sometimes drew in larger size the designs that he made for his microscopical studies. In this way the time passed rapidly.
The white substance of brain and cord, apparently, is made up of such connecting fibres, thus bringing the different ganglion cells everywhere into communication one with another. In the attempt to trace the connecting nerve tracts through this white substance by either macroscopical or microscopical methods, most important aid is given by a method originated by Waller in 1852.
On November 23rd, 1664, the President of the Royal Society was "desired to sign a licence for printing of Mr. Hooke's microscopical book." At this time the book was mostly printed, but it was delayed, much to Hooke's disgust, by the examination of several Fellows of the Society.
To my surprise, however, on entering, I discovered Thorndyke himself just finishing the mounting of a microscopical specimen. "Did you know that there is some one below waiting to see you?" I asked. "Is it anyone you know?" he inquired. "No," I answered. "It is a red-nosed, sniggering fool in spectacles.
