Joly communicates to La Nature, from whichjournal we extract the accompanying engravings, the following interestingdetails regarding his in-vestigations into the phe-nomenon of accidentalcoloration or rather rube-faction of water in thesalt marshes of Ville-neuve, a few miles fromMontpelier, in liquid is of a stronglymarked red color, re-sembling blood, and aquantity taken from thesurface and examined with the microscope showed myriadsof little beings. Their bodies were oval and long, some-times cylindrical. While young, they are colorless, after-ward turning green, and finally red. The mouth is in theform of a conical prolongation, and is retractile. Noeyes could be recognized, nor could the stomach be dis-tinctly made out. By the aid of powerful lenses, two fla-gelliform prolongations, extending from the rear of theanimalcule, were found, by agitating which it propelled it-self in the drop of water on the slide of the Fig. 1.

Onfurther examining the animalculseafter death, they appear globular inform, and hence the mistake made indetermining their nature by previousinvestigators. A single drop of alcohol,or even of fresh water, in the liquid(on the slide) in which the monadsexist, causes them to become motion-less and globular, while the same re-sult takes place if they be cut off fromaccess to the atmosphere, as it appears that respirationis absolutely necessary to their existence.
