seem to form a sort of chloragogenous gland with intracellular 
ducts. 
3. The funnel is many-lobed. The ciliated cells greatly sur- 
pass in number the ciliated funnel cells of Nephelis. 
4. The funnel seems to be threefold, 7. e.; the nephridial 
gland divides in its terminal portion into three parts, each of 
which bears a many-lobed funnel. 
5. The funnels are in communication with the nephridial 
gland. 
Concerning the terminal vesicles, I have nothing new to say ; 
but as Bolsius has contradicted my views in a letter, I have 
repeated my investigations and found the following : 
In Hirudo the terminal vesicle is spacious and lined with 
richly ciliated epithelium. The duct, connecting the vesicle 
with the exterior (terminal duct), enlarges into a secondary 
vesicle. 
This “terminal duct” is surrounded by circular muscle cells, 
the number of which is increased in two places: 1. at the open- 
ing of the terminal vesicle into the terminal duct; 2. near the 
communication of the latter with the exterior. 
In Aulastoma the terminal vesicle is very similar, except the 
circular muscle cells are confined to one place, at the opening of 
the vesicle into the terminal duct. 
In Nephelis there are no more circular muscle cells, but the 
whole vesicle seems to be provided with a feeble musculature. 
In Clepsine the vesicle is very small. The epithelium is not 
ciliated and there is not any trace of muscle cells.

The Secretary presented an invitation from the Congrés in- 
ternational des Americanistes, dixieme Session a Stockholm, 
August 3-8, 1894, for the Academy to appoint a delegate. It 
was moved and carried that the Academy accept the invitation 
and that the President and Secretary be appointed a committee 
to arrange if possible that some traveling member of the Acad- 
emy represent us at the session. 
Prof. D. 8. Martin then reported in behalf of the committee 
on standard sizes of trays, drawers, etc., and after considerable 
discussion the report was referred back to the committee to 
place the dimensions in the metric system.
