DESCRIPTION OF SFK< LES. 



5 n in width, singly, in pairs, and 

 in short chains, and filaments. 



Colonies throw out delicate 

 branches with a highly characteristic 

 appearance ; the gelatine slowly 

 liquefies, the nucleus of the colony 

 becomes yellow, and the periphery 

 iridescent. 



Inoculated in the depth of gela- 

 tine the bacilli form a cloudiness in 

 the track of the needle, and an 

 iridescent layer on the surface with 

 central depression of the gelatine 

 and commencing liquefaction. 

 Later the liquefaction produces 

 a funnel, and there is a yellow 

 deposit. 



On the surface of agar the layer 

 is a dirty orange colour. 



On potato the growth is orange 

 red with irregular protuberances, 

 and limited in growth. 



They oc*cur in water. 



Bacillus argenteo -phosphor es- 

 cens (Katz), No. I. Rods slightly 

 curved with pointed ends, 2'5 p. in 

 length, width one-third of their 

 length : singly, in pairs, and long 

 wavy filaments. 



Colonies circular ; at first trans- 

 parent droplets, later yellowish in 

 colour. 



On the surface of gelatine they 

 form a greenish-yellow film. 



In broth they produce turbidity, 

 and later a skin on the surface, and 

 on sterilised fish a pale-yellow sticky 

 growth. 



Cultures are photogenic. 



They were isolated from the sea 

 at Sydney. 



No. II. Rods with rounded ends 

 -21 n in length, '07 n in width, and 

 filaments. 



Colonies on gelatine are circular 

 with sharp contours and greyish- 

 yellow in colour : later they arc 

 irregular and granular. 



Inoculated in gelatine the bacilli 

 form a greyish-white filament in 

 the track of the needle, and a shining 

 patch on the surface. 



On the surface of obliquely solidi- 

 fied gelatine they form a blokh- 

 grey film. 



In broth they produce only 

 turbidity. 



Cultures are photogenic. 



They were isolated from ph<-ph< 

 rescent fi>h. 



No. III. Rods not so thick as 

 those of No. II., sin^lv. in pair-, and 

 filaments. They are motil. 



Colonies are white, scaly, and 

 wrinkled. 



On the surface of gelatine the 

 growth spreads over the im-dium 



On agar the growth 



In broth they produce tin I' 

 and a skin flotfcnfl on the MM- face. 



Cultures are photogenic at* 

 few days' growth. 



They were isolated from a \ > 

 of cuttle-hMi. 



Bacillus argenteo-phosphores

Colonies circular, pale In-own or 

 pale yellow and. after liquefaction, 

 with radiating processes extending 

 into the surrounding gelatine. 



Inoculated in the depth of gela- 

 tine there i- a <_ r n>wth in the track 

 of the needle, and near the surface 

 a cup-shaped area of liquefact: 



In broth they produce tnrl.; 

 and form a skin on the surface. 



On sterilised fish they form a 

 yellow layer. 



They are photogenic but not 

 markedly so. 



Bacillus aurantiacus (Frank 

 land). R

' lonies are prominent and pale
