THE CHALCICOMULA COLONY TEST. 



About the middle of June of 1905 a representative culture from this location 

 was introduced into a test location about a mile from the Chapultepec test, and 

 there thrived well and gave in the following generations a well-defined group, 

 that was constant in appearance. In figures 152 to 156 are shown the resulte

 parent location during the same period. In the original location the population
