designates the species as homothallic and heterothallic, corres¬ 
ponding to monoecious and dioecious forms among the higher 
plants. Quoting again: In all species of both homo- and hete¬ 
rothallic groups the process of conjugation has been carefully 
followed, the swollen portions (progametes) from which the 
gametes are cut off do not grow toward each other, as currently 
believed, but arise as a result of the stimulus of contact between 
more or less differentiated hyphae (zygophores) and are from the 
outset always normally united. 
The Sphere of Bacteriology was the subject of a paper 
by Professor Edwin Oakes Jordan before the Section of Bacte¬ 
riology, International Congress of Arts and Science, Universal 
Exposition, St. Louis, published in Science, Nov. 18, 1904. The 
interesting and instructive address closes with these words: It 
is not possible to estimate the loss to literature, science and art 
since the dawn of intellectual life which must be laid at the door 
of the infectious diseases. The relations of bacteriology to public 
hygiene, if properly appreciated and cultivated, will lead to an 
improvement in the conditions of life which will enhance both the 
ideal and material welfare of the race and will give greater assur¬ 
ance that each man shall complete his span of life and be able to 
do the work that is in him.
