B.cloacffi that pften interfers with the growth of B.coli in 

 fermentation tubes, frequently gains the upper hand. Er- 

 rors are likely to arise when an examination of river 

 water is made. Litmus lactose agar facilitates the sepa- 

 ration of B. coli especially if the plate be examined in 24 

 hours. 



Sporotrichum in Abscess. — Prof. L. Hektoen has ob- 

 tained it from a case of refractory abscess which started in 

 an abrasion of the left index finger caused by a blow with 

 a hammej. The fungus has tenatively been placed in the 

 genus Sporotrichum by Dr. Erwin F. Smith. It is the 

 Sporothrix of Schenck. The fungus grows well in ordin- 

 ary media. It has a separate branching mycelium and 

 bears clusters of five or six spores around the end of the 

 branch and single spores laterally. It is destroyed at 

 about 60 °C. 



Hybrid Coffees and Disease. — In the government 

 gardens at Mysore several new forms of coflfee have been 

 cultivated which appear to be hybrids. The hybrids com- 

 bine the characteristics of Coffea liberica and C. arabica. 

 The most remarkable thing about these hybrids is their 

 immunity from coffee leaf disease which has been so de- 

 structive in India. (Gard. Chron. III. 25 : 240.) 



Thermal Death Point of Sporotrichum Globulife- 

 RUM. — Duggar (Bot. Gazette 27 : 131), states that agar 

 cultures of this entomogeneous fungus are inhibited in 

 their growth when exposed for 24 hours to 35, 37.7 and 

 and 40.5"C., but a few hours after germination had start- 

 ed they could withstand considerable longer exposure to 

 these temperatures. Three hours exposure to tempera- 

 tures of 46.1 and 51.6 was sufficient to destroy nearly all 

 growths of spores. The mycelium of the fungus is quite 

 resistant.
