Fed upon the larva of the Three-horned Osmia or of the Blue Osmia, Anthrax sinuata, whether of handsome proportions or a dwarf, is still Anthrax sinuata; fed upon the allowance of the Anthidium of the empty Snail-shells, the Anthidium of the brambles, the Megachile or doubtless many others, the Burnt Zonitis is still the Burnt Zonitis.
The introduction of tame sheep early in the '80's was followed by a most destructive anthrax, which not only destroyed immense numbers of tame sheep, but also exterminated the wild ones, which appeared to be especially susceptible to this disease.
To leave the cell of which he has eaten the owner, the Anthrax becomes a perforating machine, a living tool from which our own industry might take a hint if it required new drills for boring rocks.
The radical of the germinating seed is no more persevering in its efforts to descend into the cool earth than is the Anthrax grub in creeping into the lump of mortar. What inspiration urges it towards its food at the bottom of the clod, what compass guides it? What does it know of those depths, of what lies therein or where? Nothing. What does the root know of the earth's fruitfulness?
And so when, with the aid of his laboratory associates Duclaux and Chamberland and Roux, he took up the mooted anthrax question the scientific world awaited the issue with bated breath.
It is seeking to combat disease in its centers of diffusion. Instead of attempting to quarantine against the Orient, it is aiding the Orient to overcome those conditions which do harm alike to Orient and Occident. Plague, anthrax, yellow fever, cannot exist in one country without harm to all.
Even so the initial form of the Anthrax might well continue, not in inactivity, but in stubborn attempts to overcome the thick bulwark. My young worms, when transferred with their provisions into tubes, remained stationary, on the average, for a couple of weeks.
Anthrax is one of the oldest animal diseases, and early in the history of the race it existed as a plague in Egypt. It most commonly affects cattle, sheep and horses. Man contracts the disease by handling wool and hides from animals that have died of anthrax, and by accidental inoculation in examining the carcass of animals that have died of the disease. Cause.
Let us resume the story of the wee animal, now recognized as the genuine origin of the Anthrax. It is a tiny worm about a millimeter long and almost as slender as a hair. It is very difficult to see because of its transparency. When tucked away in a fold of the skin of its fostering larva, an excessively fine skin, it remains undiscoverable to the lens.
Moreover, since, according to one of our recent Communications, anthrax is not recurrent, each of our attenuated anthrax microbes is, for the better-developed microbe, a vaccine that is to say, a virus producing a less-malignant malady.
