56 THE ORIGIN OF LIFE 



5, Fig. 25. The bodies shown in Fig. 2, which 

 I speak of as Fungus-germs, have been particu- 

 larly abundant in many of the yellow solution 

 tubes and only in them. They are spherical, and 

 often occurred in large masses, the heaps having 

 then a brownish colour. They are evidently quite 

 different from ordinary Torulse. 



In Plate 4, Fig. 20 A, there is shown a rudi- 

 mentary Penidllium, and in Fig. 21 a more de- 

 veloped form of such a Mould taken respectively 

 from tubes Nos. 99 and 98. 



Even a cursory examination of the Plates will 

 suffice to show that we have here to do with no 

 mere pseudo-organisms, such as have been de- 

 scribed of late years by many workers with un- 

 heated solutions containing silica and various 

 salts. 1 



Doubts have been previously expressed, however, 

 as to whether the organisms taken from my tubes 

 are really alive, and have actually developed 



1 A full account of such investigations will be found in the 

 works of Albert and Alexandre Mary, entitled Etudes experi- 

 mentales sur la generation primitive, 1909; and Evolution and 

 trans formisme, 1910, tome iv., pp. 305-325; as well as in a 

 work by Leduc of Nantes, entitled Theorie physico-chimique de 

 la vie et generations spontanees, 1910.
