LEFT INFUSIONISM 154 INGERSOLL turnal exacerbations, lasting from four to eight days, sometimes complicated with bronchitis or even pneumonia. A form known as Spanish Influenza was epidemic in the United States and in many other countries in 1918 and 1919, and caused thousands of deaths. INFTJSIONISM, the doctrine that the human soul is an emanation from, or an influx of, the Divine Substance. It is akin to the teaching of Pythagoras and of the Stoics. Its defenders in Christian times have relied on Gen. ii: 7. Infu- sionism is opposed to Traducianism, and to Creationism, the doctrine accepted by the Eastern and Western Churches. INFUSORIA, the name first given by Otto Frederick Miiller to the mostly mi- croscopic animalculae developed in or- ganic infusions. A drop of water from a weedy or other pool or ditch, viewed by the microscope, contains them in count- less numbers. Pritchard divided them into Bacillaria, which were clearly vege- table, Phytozoa on the borderland be- tween animals and plants, and Protozoa, Rotatoria, or Rotifera, and Tardigrada, clearly animal. Professor Huxley ele- vated them into one of the eight primary groups into which he divided the animal kingdom. They have neither vessels nor nerves, but possess internal spherical cavities. They move by means of cilia or variable processes formed of the sub- stance of the body, true feet being ab- sent. They occur everywhere, in salt as v/ell as in fresh water. One, Noctiluca, is believed to take a great share in pro- ducing the phosphorescence of the ocean. INFUSORIAL EARTH, a siliceous deposit formed chiefly of the frustates of Diatoms. It is used as Tripoli pow- der for polishing purposes, and as an ab- sorbent of nitro-glycerine in making dy- namite.
