""jrnlri/rnT^sm '] Jottings hy a Student of Heterogemj. 27 



Oct. 6th. — Wall in my garden, Chlorococcus with Lyngbya ; large 

 single oval cells, with terminal vacuole like large Euglena (see 

 Feb. 5, 1869— 31oss-ceUs). 



June Itli. — On the edge of a tumbler containing Mosses and Con- 

 fervje in water (one mouth) a green rim of distinct Chlorococcus. 



June 12th. — Chlorococcus in tumbler containing Confervfe. 



June 19th. — Water containing Conferva, resting sj)ores (Chloro- 

 coccus ?). 



Jail/ 2Sth. — On side next light of a bottle marked A, into which 

 some Conferva rivularis was put (Nov. 9, 1868) are masses of round, 

 green Chlorococcus. A floating film or fi-ond near the bottom consists 

 of smaller oval, green cells ; no moving life. The bottle has a ground 

 stopper in, and contains thi'ee-fourths water. 



July 31st. — Green film on side (A) ; Chlorococcus, mixed with a 

 few Mucedo filaments. 



Sept. 2nd. — Each cell of Chlorococcus (side A) has a centre nucleus. 



Sept. 5th. — The same. 



Nov. 15th. — Cells from side A nearly all oval, and nucleated. A 

 few straight, small-beaded filaments, as if still vibrions. 



The following observations refer to Palmella cruenta. (See 

 " Jottings," Aug. 20th, April 21st and 27th, and May 11th.) 



June 18//t. — On a damp wall, with every variety of green and red 

 patches intermixed. Palmella cruenta and Oscillatoria containing 

 red cells, monads, green, round, oval, and binucleated cells, congre- 

 gated round cells as Chlorococcus, rudimentary and perfect tubules 

 of Oscillatoria, larger green cells as of mosses inextricably intermixed 

 with red Palmella cells, branched moss cells and moss tubules with 

 vacuoles, containing nmnerous chlorophyll cells. 



July 23rcl. — Palmella cruenta, red and green cells inextricably 

 intermixed, single, double, multiple cells of Chlorococcus, tubules of 

 Lyngbya, with separate chlorophyll cells, larger moss cells, round, 

 oval, and oblong. 



Aug. 12th. — In stagnant water containing Conferva? is a red film, 

 very small red globules in patches. 



Sept. ord. — Similar observations. There are flat green Paramoecia, 

 green Gonidia, all sizes ; distinct Euglena. 



Oct. l-ith. — Palmella cruenta. Green and red patches inextri- 

 cably mixed, in red part mostly red cells, a few green Gonidia, round 

 and multiple ; some oval, oblong, and perfect Oscillatoria. In green 

 part larger Chlorococcus with oval cells; close to this is a perfect 

 patch of Oscillatoria in all stages, from round to oval, oval to oblong, 

 oblong to perfect tubules. 



In observations on Oscillatoria, see " Jottings," May 10th and 

 11th, and April 21st. 



Jan. Slst. — Green slime from canal bank, on moist mud, Euglena, 

 common, and with vacuole ; oval, elongated, and perfect tubes of 

 Oscillatoria. 



Jan. 31st. — Oscillatoria formerly Palmella cruenta, every stage
