Are Potatoes Fungi or Not? 
By ARTHUR M. EpwARDs, M. D. 
There comes now a discovery which makes potatoes 
fungi and not the root of the plant upon which they grow, 
which is so extraordinary, and withal is made by a com- 
petent botanist, that it makes us pause. It seems that 
M. Noel Bernard a perfectly competent botanist has made 
this discovery and it seems so rational that we are bound 
to believe it. He notes that potatoes gathered for plant- 
ing have a resting period of several months, after which 
the vegetation is resumed. Even when kept in cellars 
which are well-lighted and well-aired the part commonly 
and popularly known as “eyes” develops and from them 
stalks also appear. Oultivators are careful to allow this 
first developement to take place normally, for cultivation 
succeeds well when the sprouted eyes are planted. So
