MEETING OF THE BIOLOGICAL CLUB. 
Orton Hall, March 2, 1903. 
Mr. Quiroga gave a paper on his native country, Argentina. 
It served to call the attention of those who heard it, to the fact 
that Argentina is not to be compared with such Latin- American 
countries as Venezuela and the Central American Republics. 
The facts given and the pictures exhibited showed very plainly 
that in prosperity and commercial advancement the country is on 
a level with the United States. The paper took up exhaustively 
the geographical relations, topography, geology, physical geo- 
graphy, climate, agriculture, transportation, industries and edu- 
cation. Whenever practicable tables were given showing com- 
parisons with the United States. In some respects, for example 
in the animal industries, the comparison was decidedly in favor 
of Argentina. 
Prof. Osborn stated that as he read the census reports he made 
out a better case for the United States than did Mr. Quiroga. 
The second paper was by Prof. Schaffner on “Mendel’s Law 
of Heredity. He gave a short history of Mendel’s work and 
explained the meaning of the law. In order to get the characters 
of only one of the parents in the offspring, the sex cells from which 
it comes must have been pure. If we believe that in the reduction 
division of the sex cells the division is longitudinal, there is no 
possibility of an unequal distribution of hereditary tendencies. 
But in a transverse division, segregation of characters is possible. 
In cytology there is nothing to indicate the percentage of hybrids 
being as Mendel found it. He thought that the ratio must be 
dependent rather on some balance of external conditions. He 
also questioned whether the statistical method was entirely 
reliable.

Notice to Subscribers. 
Beginning with the first issue of Volume IV the price of The 
Ohio Naturalist will be one dollar per volume instead of fifty 
cents as heretofore. At the present price the editors can not 
publish nearly all of the desirable material offered. At the 
increased subscription the management hope not only to publish 
more papers but to be able to publish longer papers and thus 
make the Naturalist of more value to those interested in 
special subjects. The new price applies to subscribers not mem- 
bers of the Biological Club of the Ohio State University.
