of groups of homologous vital substances, especially proteins, carbohydrates, 

 and fats of plants, are being studied, the results in every instance being in 

 entire support of the findings of the hemoglobin inquiry, and therefore tend- 

 ing to the establishment of a new and preeminently important law in biology. 

 At least another year of inquiry must elapse before the results of this re- 

 search will be ready for report in detail.
