SUMMARY OF CURRENT RESEARCHES. 
garin lard than in margarin butter. Pathogenic bacteria were not dis- 
covered in margarin or its products, and all the bacteria found were 
saprophytes. From margarin two bacilli were isolated — Margarin- 
bacillus a and /3. From margarin butter four hitherto undescribed 
microbes were obtained — Diplococcus capsulatus margarineus , Bacillus 
viscosus margarineus , B. rhizopodicus margarineus, and B. rosaceus 
margarineus. 
Vibrios and Spirilla of Liquid Manure.* — Herr Kutscher succeeded 
in isolating from liquid manure eight different species of curved bacteria. 
They were cultivated in the following way : With each 80 ccm. of the 
manure placed in Erlenmeyer’s flasks were mixed 8 ccm. of a 10 per 
cent, pej) ton-salt solution, and then the flasks incubated for 24 hours at 
28°. The flasks were then examined to see if any species of vibrio had 
increased. If this were the case several loopfuls were removed, and 
agar-plates inoculated with dilutions thereof. If no vibrios were found, 
the flasks were returned to the incubator until vibrios were discovered, 
though occasionally they were not. The different species were then 
isolated on agar-plates. Among these were four slightly bent species 
called vibrios, among them being one with all the characters of Spirillum 
serpens, and four strongly curved species called spirilla. Of the latter, 
No. 1 is a slender spirillum, which was isolated by the author also 
from swine’s excrement, and is identical with the delicate spirillum 
observed by Smith in pigs’ dung. No. 2 corresponds morphologically 
to Spirillum tenue, No. 3 to S. undula, and No. 4 to S. volutans.
