^{page 289 note 1} Carus has figured and given a description of confervæ growing on a dead salamander. (Nova Acta, vol. ii. p. 493.) I may here observe, that similar confervæ may be produced at will, by allowing frogs or gold fish to remain, after death, some time in water without changing it. In a few days they become covered with a white efflorescence, which, examined microscopically, is found to consist of long transparent tubes, jointed at regular intervals. I have frequently examined confervæ thus produced: they are different from those which grow on these animals during life.
