274 A few Remarks on Dr. Bastian’s (yon ere 
ammonia had been applied to the liquid to arrest instantaneously 
all movement of Paramcecia, &c.* 
In Art. V., M. M. J., Jan., 1870, pp. 25, 26, are the details 
of an experiment with water passed through a piece of lint exposed 
to the air, in which monads were first apparent; and, Sept. 17th, 
monads, some active, others inclining to germ colour; Oct. 8th, 
a large deposit of green Chlorococcus. The following notes occur 
subsequently :-— 
Nov. 1.—Chlorococcus round ; many oval; smaller; a few large, 
with vacuole ; a few short tubules, as if soridia. No acuminated cells, 
as of Oscillatoria. 
Dec. 31.—Gonidia in clusters, tending to lines. No filaments. 
July 3.—Floating on surface a large number of filaments of 
Lyngbya, with Chlorococcus—Gonidia. 
This bottle was kept closed except at the periods of examina- 
tion. Care was taken to prevent the introduction of any foreign 
matter by the instruments used to remove the substance for 
examination. The conclusion, therefore, is that Lyngbya may be 
developed from Monas; and the opinion is supported by the follow- 
ing observations; and the argument deduced from it supports 
Buffon’s view, here reproduced, that all organic matter consists of 
basement cells having more or less hereditary tendency. 
But the following experiment shows also that similar forms of 
vegetal product are evolved from different plants :— 
June 4th, 1870.—I put a piece of Jungermania asplenoides, 
marked A; a few stalks of Polytrichum commune, marked B; a 
small quantity of Sphagnum palustre, marked C; and a few sprigs 
of Hypnum rutabulum, marked D, into 2-oz. bottles, filled with 
water and exposed to light and air. A and D were less vigorous than 
B and C, and had less root. 
June Tth.—No moving life visible. 
5, 8th.—Numerous Monads in B and C. No moving life in 
A and D. 
June 9th.—B, Monads very active ; a patch of green oval Gonidia. 
OC, Monads transparent; oval; very active. A and D, no moving life. 
June 11th.—One large Pseudo-gonidium from B. OC, a large 
number of transparent Monads ; some moving rapidly ; others slowly. 
A and D, no moving life. 
June 17th.—A, no moving life. B, green Gonidia, round. C, 
transparent, globular, moving cells. D, one transparent oval cell. 
June 25th.—A, one green Gonidium, still. B, large number of 
green Gonidia, still. OC, round and oval transparent cells, still; a 
large number of active Monads. 
July 3rd.—C, surface covered with green cells, round, of all sizes, 
to full-sized Chlorococeus; oval cells from small size to medium-
