ends, which give up the stain when treated by Gram's 

 method. Gelatine is rapidly liquefied. The plate-culture 

 shows in the centre of the liquefied colony a nodule of the 

 size of hemp-seed, with fringed edges. There develops a 

 thick greyish -white un wrinkled coating upon agar even in 

 one day. On potato a brownish-yellow layer forms. The 

 cultures generate ammonia and smell like decomposed 

 urine. This bacillus seems to be nearly akin to the Proteus 

 vulgaris (see p. 175). 



The Staphylococcus pyogenes albus and aureus are also 

 very often found in cystitis.
