776 REPORT—1904. 
to be sense-organs, is sensitive to the pressure of the statoplasts; and we know 
from zoological evidence that heavy bodies resting on a sensitive surface can 
function as a sense-organ for gravitation. Finally, the experimental evidence, 
though not absolutely convincing, has not revealed any absolute bar to our belief 
in the statolith theory, and has brought to light a number of facts harmonising 
with it ina remarkable manner. It seems to me that the theory of Némec and 
Haberlandt may fairly hold the field until a better theory of graviperception and 
a better theory of the function of falling starch-grains are established.
