After describing a series of experiments made by removing the antennte 

 from various species of insects, the author says, " I do not see that my ex- 

 periments enable us to prove anything as to the nature of the function of 

 the antennas, except to indicate that the insect's brain is as it were pro- 

 jected into them, and that their nerves probably possess nucleated cellsi 

 homologous v.itli those of the ganglia from which the sense-nerves origi- 

 nate."
