102 SUMMARY OF CURRENT RESEAUCHES RELATING TO 



(1) Bacillus argenteo-pliosphorescens liquefacicns, obtained from sea- 

 water at Boncli ; its cultures, liquefying gelatin, emit in the dark a 

 silvery light, which, however, is the weakest of the six kinds hitherto 

 found ; (2) Bacillus argentco-pliosphorescens II., derived from a luminous 

 piece of a small squid (Loligo), and, at the same time, from luminous 

 pieces of the Sydney gar-fish (Hemirhamphus intermedins Cant., H. 

 welanochir Cuv. and Val.) ; (3) Bacillus argenteu-phosphorescens III., from 

 the squid already mentioned. Neither of the latter micro-organisms 

 causes liquefaction of the gelatin. They give off in the dark a handsome 

 silver light, much more intense than that of the first-mentioned, but 

 resembling that of the previously exhibited Bacillus argenteo-phospho- 

 rescens (now to be designated I.). From this latter Nos. II. and III. 

 distinctly differ. 



Lectures on Bacteria.* — The second improved edition of Prof. A. 

 Do Bary's Lectures on Bacteria has been translated into English by 

 Mr. H. E. F. Garnsey, and revised by Prof. I. B. Balfour ; it will be 

 very useful as a general view of the subject to all who are interested in 

 these organisms.
