1G7. Browne, Willi \m W. The isolation of bacteria from salt and salted foods. [Ab- 

 stract.] Absts. Bact. 4: 11-12. 1920. — Reddening of Baited fish is due to growth of 2 organ- 

 isms, a spirochete producing an opaque pink coloral ion and a bacillus producing a transparent 

 red coloration. They are intimately associated and arc difficult to separate in pure culture. 

 No growth occurs on media containing less than 16 per cent sea salt ; optimum concentration 

 seems to be saturation; optimum temperature, 50° to 55°C. Both are strictly aerobic, both 

 difficult to stain, and neither affected by sunlight (8 hours). Morphology of both organisms 

 depends on concent rat ion of salt, the largest forms (Mm) appearing on saturated solutions and 

 the shortest (2/j) on media of lS-per-cent concentration. — [From author's abst. of paper read

 Bact. 4: 19. 1920. — "In the course of routine diagnostic work it was observed that some of 

 the sera used for identifying typhoid failed to agglutinate certain strains. This fact seemed 

 to indicate that there might be types of typhoid bacilli. The strains used were from as widely 

 separates sources as possible; 5 were isolated in Kansas, 4 from Europe, 1 from California, 

 the others from various parts of the East and middle West. Culturally they were identical, 

 with the exception of 3 strains, which gave a deep blue color to litmus milk after a slight 

 initial acidity lasting 4 days; the others remained pink. — Representative strains were selected 

 and rabbits immunized. Cross agglutinations were made using all the organisms against 

 each serum. It was found that they readily fell into 4 groups. Groups I, II, and III are quite 

 distinct, while group IV is agglutinated by both type I and II sera." — [Author's abst. of paper

171. Eaton, Paul. A device for the rapid measurement of bacteria. [Abstract.] Absts. 

 Bact. 4: 4. 1920. — A mechanical stage the movement of which is brought about by the use 

 of a screw and nut, the screw being actuated by a rather large worm-wheel. The mechanical 

 motions which bring about movement of stage are recorded by a counter of the "mile-register" 

 type. [From author's absts. of paper read before Soc. Amer. Bact.] — D. Reddick.

 4: 6. 1920. — Four varieties of Azotobacter isolated from soil have been studied and are found 

 to have a very complex life cycle with extreme polymorphism. The various forms encountered 

 are briefly enumerated. [From author's abst. of paper read before Soc. Amer. Bact.] — D.

 [Abstract.] Absts. Bact. 4: 15. 1920. — Six species are recognized: Bact. dysenteriae (Shiga- 

 Kruse), Bact. ambiguum, Bact. flexneri, Bact. sonnei, Bact. dispar, and Bact. alkalescens. 

 The interrelationships and cultural differential characters are indicated in a table. [From
