 two has now been traced. Working upwards 

 through the clay the biologist finds what he 

 took to be an organism of the clay leaving 

 his domain and passing into a world above

 themselves in ever attenuating forms in the clay 

 beneath. What is to be made of this discovery ? 

 Once more. Is it a Stigmaria or a Sigillaria
