The period which has elapsed since the first planting, which 
is the one recorded in my former paper, varies from one to two 
years. 
1. MERISMOPEDIA FLAVA VARIANS. 
The morphology represents now a well packeted Sarcina in- 
stead of a Merismopedia and the gelatin is slowly liquefied, in 
one culture in 33 days, and in another made at the same time 
only in 50 days. The characters on the other media have not 
changed, except that nitrate is rather less quickly reduced, the 
full reduction not being obtained till 28 days. 
6. Micrococcus SIMILIS. 
The cultures are dead. 
3. MicrococcUs CEREUS AUREUS. 
The characters have not changed. 
12. MicrRococcUS CREMOIDES AUREUS. 
The cultures faded to the color of I. cremoides, but retained 
their growth characters. Fresh cultures with the normal orange 
color were readily obtained from the air. 
14. Micrococcts CREMOIDES ALBUS. 
The cultures were lost, but those of JZ. cremoides had faded 
to pure white, retaining their other characters. 
21. MERISMOPEDIA FRAGILIS. 
The cultures are dead. 
93. MERISMOPEDIA MOLLIS. 
Characters scarcely changed. The growth is less abundant 
than a year ago, the orange color most distinct in the condensa- 
tion water in the bottom of the tube. Lactose litmus agar is 
made blue. 
25. Micrococcus DISSIMILIS. 
Characters unchanged except that the cells were seen to be 
associated in pairs and fours as well as singly, thus representing 
a Merismopedia. 
33. MERISMOPEDIA MESENTERICUS CORRUGATUS. 
The growth characters are exactly the same, and in addition 
a slight pink tint was seen in the liquefied gelatin. Milk is af- 
fected exactly as by B. lactis erythrogenes, being apparently co- 
agulated, but on boiling the coagulum disappears. <A careful 
examination of the cells shows them to be slightly elongated, 
yet associated in pairs and fours. A second culture, also
