ually dart fromeach other, snapping the connecting fibre of sarcode in the middle,so that two perfect forms are set free, as in (\ and 7. This, in the course of from two to three minutes, is once morebegun and carried on in each half successively, so that there is anincrease of the form by this means in rapid geometric ratio. But this is an exhaustive process vitally, for after a period vary-ing from eight to ten days there always appear in the unalteredand unchanged field of observation normal forms, with a remarkableditlluent or amoeba-like envelope, as seen in figs, s and .».

MONAS 757 sometimes swim and sometimes creep, amoeba-like, by pseudopodia ;but directly the diffluent sarcode of one touches that of anotherthey at once melt together, as in dg. in, A. This leads to the rapidapproach of the oval bodies of the two organisms, as in fig. 11, B,resulting in their fusion, as in figs. 12, 13, 14, and a still conditionof the sac (fig. u) for a period of not less than six hours ; when itbursts, as seen in fig. 15, pouring out an immense host of exquisitelyminute H/I»,-I^. as shown in fig. i:>. These are opaque or semi-opaque,but by observation upon them at a temperature of 65° to 70° Fahr.,they in the course of thirty minutes become transparent, elongate,as in figs, id and 17, and. continuing to grow, assume the conditionsand sizes represented in figs, is and ID; and we were able to tracethem through all their changes of growth from the spore into theadult condition, as at fig. •_>
