But, instead of the terminal cell being filled with the usual densely crowded cluster of dark green granules constituting the rapidly forming spore, it contained hundreds of actively moving, nearly transparent zoospores, and nothing else. Not a single chlorophyl granule was to be seen.
What is true of the newt is true of every animal and of every plant; the acorn tends to build itself up again into a woodland giant such as that from whose twig it fell; the spore of the humblest lichen reproduces the green or brown incrustation which gave it birth; and at the other end of the scale of life, the child that resembled neither the paternal nor the maternal side of the house would be regarded as a kind of monster.
But the protoplasmic contents of some of the cells of which the plant is made up occasionally divide, by a method similar to that which effects the division of the contents of the Peronospora spore; and the severed portions are then set free as active monad-like zoospores. Each is oval and is provided at one extremity with two long active cilia.
C represents the mature plant, entirely emptied of its spore contents, there remaining inside only a few actively moving spermatia, which are slowly escaping. The spermatia differ from the spores and young plants in being smaller, and of possessing the power of moving and tumbling about rapidly, while the spores of young plants are larger and quiescent.
"Under the microscope, the germ of, say, tetanus is a minute bar with spore at the end like the head of a tadpole. Of what is this cell composed?" "Probably of a jelly-like substance with excessively minute filaments, but we don't know. We are at the limit of the microscope. We trace certain processes, we even dissect certain cells, but elemental composition of plasm remains a mystery."
These preventives only prove efficient on condition that they be used persistently. Let our vigilance be lacking for an instant, and the enemy will enter to work destruction, for it only requires a spore less than a hundredth of a millimeter in diameter to produce the most serious affections. Fortunately, and it is again to Mr.
Dawson's results are the more remarkable, as the numerous specimens of British coal, from various localities, which I have examined, tell one tale as to the predominance of the spore and sporangium element in their composition; and as it is exactly in the finest and purest coals, such as the "Better-Bed" coal of Lowmoor, that the spores and sporangia obviously constitute almost the entire mass of the deposit.
I could not deny it, nor that there was ill blood between the lads; and then young Brocas, who was later on Portsdown than we were, remembered high words, and had thought to himself that there would be a challenge. And next old Goody Spore recollects seeing Master Sedley and another soldier officer out on the Portsmouth road early that morning.
The bacteria clinging to the dry hair can grow but little, if at all, and those in pure water multiply very little. When dried as dust they are entirely dormant. But each individual bacterium or spore has the potential power of multiplication already noticed, and as soon as it by accident falls upon a place where there is food and moisture it will begin to multiply.
He added the notes that Maril had made for him, of Murgatroyd's pulse and blood-pressure after the injection of the same culture that produced fever and thirstiness in himself and later without contact with him or the culture in Maril. He put a professional comment at the end. "The culture seems to have retained its normal characteristics during long storage in the spore state.
