These observations relate chiefly to the colour, spicules, and sarcode substance of what is believed to be a new species of fresh- water sponge. Little is said of the reproductive bodies.

" I think, (says M. Lemaire), that the Infusoria so abun- dantly diffused in nature, and which have been proved to occup in the seminal fluid of almost all known animals, and in the male organs of nearly every plant, constitute the primum movens of the pheno- mena of fermentation, of germination, and of fecundation, but that, for their action to manifest itself, contact (reunion) with albuminoid matters seems indispensable."

M. Max Schultze differs from M. Brandt and Dr. Gray as to the nature of Hyalonema, which he regards as a true sponge, not a polype parasitic on sponges.
