70 Occurrence of Bacteria (Bacilli) in Living Plants. 



This would give a proportionate amount of — 



Felspar, 2-1 ; Quartz, 1*6; RO Minerals, 1. 



This shows that such a compound as the above might, in 

 consolidation, crystallise in the form of one of the rocks 

 belonging to the Noyang group ; and a compound formed 

 by the fusion of different proportions of the igneous magma 

 and the sediments might produce any one of them. 



Such fusions have taken place in the Gippsland area, at 

 the close of the Silurian age, to an enormous extent, and 

 the influence of the absorbed sediments on the invading 

 igneous magmas cannot be overlooked. 



It seems to me that such possibilities, in the formation of 

 igneous rocks, have not yet been sufficiently regarded by 

 petrologists.

 Living Plants.

In these days of germ-theory and of research after bacteria 

 discoverable in the tissues of animals, and supposed to be 

 elements of disease in some form or condition, and when we 

 are called on to become familiar with such terms as these — 

 Sphsero - bacteria, Micro - bacteria, Desmo - bacteria, Filo- 

 bacteria, and Spiro-bacteria, Bacilli and Micro -cocci; and 

 then some of their results, as Bacteruria and Pathogenous- 

 bacteria, in relation to a whole host of maladies, and the 

 question of mutability of bacteria, it may not be without 

 interest to bring before the notice of the scientific mind that 

 bacillus (a sub-genus of bacterium) is to be detected in living 

 plants. 



A few years ago there was a notice in the Journal of the 

 Royal Microscopical Society of England to this effect, that 

 bacteria had been found in the crushed tissues or cells of 

 plants ; and the question was asked, as this had been noticed
