of 50°C., and covered for 1 hour, were the only ones completely sterilized. It was found, 

 however, that enough HgCl2 solution remained on the surface of the tubers to exert a decided 

 antiseptic action. — Similar tests were also made with both Rhizoctonia solani and Spondylo- 

 cladium airovirens. — By running a large number of checks with treated and untreated seed, 

 it was found possible to measure the percentage of infection resulting from the presence of 

 Rhizoctonia and Actinomyces in the soil. — B. B. Higgins.

 191&: 1-22. Fig. 1-7. 1919. — Experiments on the control of club root {Plasnwdiophora

2129. Church, Margaret B. The relation of mosaic disease to pickling of cucumbers. 

 Phytopath. 11: 28-29. 1921. — Cucumbers visibly affected with mosaic disease do not make 

 good dill pickles. They do not clear up properly in the brine. — B. B. Higgins. 



2130. Reddick, D. Foot rot of tomato. Phytopathology 11 : 29. 1921.— The name "Foot 

 rot" for the tomato disease caused by Macrosporium solani is claimed to be preempted because 

 of previous use in connection with the disease caused by Phytophthora cryptogea. Use of 

 generic names of causal organisms as descriptive adjectives is proposed. — G. H. Coons.

 Union of South Africa 2: 133-136. Fig. 1-2. 1921. — A report on the presence of organisms 

 causing decay in fruit in cold storage rooms in Cape Town. It is stated that the condition

2132. Wagner, Esther A., and W. F. Monfort. Lactose broth for isolating Bacterium 

 coli from water. Amer. Jour. Public Health 11 : 203-208. 1921.— The authors advise a broth 

 containing 2 per cent peptone, 0.2 per cent lactose, and 0.001 per cent gentian violet, to be 

 used with an equal volume of water. It is claimed that the use of the gentian violet makes 

 possible sterilization of the medium by pasteurization in place of autoclaving, thus obviating 

 the hydrolysis of the sugar which occurs at autoclave temperatures. — C. A. Ludwig.
