94 TRANSACTIONS OF THE [ FEB. 4, 
April 8th, 1888. This morning I have been studying the 
Termites (Hutermes), with the following results :—I watched 
their actions for forty-five minutes without intermission or 
abatement of interest, and, using a more powerful lens, I con- 
firmed many of my previous observations. I wished to-day to 
note whether the Hutermes would attack ants or other insects, 
or be much disturbed by their presence. So I made a break of 
about three-eighths of an inch in a gallery on a fence-post. 
None but those with the shiny black heads with beaks (nasuti 
soldiers) put in an appearance for at least fifteen minutes. So 
I caught a common black ant, killed it, and pinned it in the 
centre of the broken gailery. The nasuti soldiers approached 
it very cautiously with their feelers and seemed afraid of it. In 
a few moments a worker came with the prepared glue, barely 
touched it, then turned around and dropped a speck of glue, 
then another, and so on until six had done so; then some 
grains of sand were brought and placed on the ant, which was 
now securely glued down. I withdrew the pin, but the ant was 
fast and immovable, and they seemed to leave this work. In 
the meantime, I had broken other galleries, to which I was 
giving attention. One, a very small break, I noticed them clos- 
ing up without using any grains of sand, or but a very few. I 
watched this closely: some of the ejections were darker 
than others ; some were very profuse, while others were scarcely 
discernible, but all of about the same consistence. ‘he color 
at first was a light yellow, but in a moment or two of exposure 
to the sun it became very dark or brownish-black. The 
workers, when making this deposit, made a sweep with the ab- 
domen, spreading it along the edge of the gallery. While the 
aperture of the gallery was being closed, the black-heads— 
nasuti soldiers-—kept their heads and antenne over the edge, 
until finally there was only room for the antenne of one in the 
opening ; these were then pulled in,—another drop, and the 
world to them was shut out. While watching this operation I 
found that my little prisoner—the black ant—had been excluded 
from the gallery by building a curved portion around him, join- 
ing the ends of the former gallery,——just wonderful! (Fig. 4). 
May 3d. Yesterday I met our friends the Termites again, 
and found them more interesting than ever. I disturbed a> 
block of wood, of which they had entire possession, and turned 
it up edgewise. Jn doing this, their runs or galleries were 
broken, and several workers were wounded and crushed. ‘These 
were removed at once by other workers, and taken carefully into 
the galleries. ‘The order to do this seemed to me to be given by 
the soldiers, but in no case did they assist in their removal. I 
watched with interest their evident intention of connecting the
