Professor G. B. Grassi 



Professor Dr. G. B. Grassi, professor of comparative anatomy and 

 entomology in the University of Pome, and director of the institute of 

 comparative anatomy; a very famous man of many-sided accomplish- 

 ments, who, with Celli, studied the relations of malaria and the 

 Anopheles mosquito, and was the first to point out that while early 

 experiments with the carriage of malaria hy mosquitoes of the genus 

 Culex were negative, they might be successful with those of the genus 

 Anopheles, just as Boss in India failed with his initial work with Culex 

 and succeeded with the "dapple-winged" mosquitoes of the genus 

 Anopheles.
