100 Mr.T.S. Savage on the Termitide of West Africa. 
pany the labourers and are found with them in their covered ways 
along the sills, floors and roofs of our houses, differ palpably mm 
these respects from those of T. bellicosus. I made known my 
doubts on this point to my correspondent Mr. Westwood of 
London, proving the truth of my statement by specimens taken 
from my own dwellings, but, unfortunately, the bottles containing 
them were broken, and I failed of my object. I consider these 
house-eaters as the 7. arborum of Smeathman. One of their 
nests, indeed, I found in the roof of my office, and by them great 
damage was done to the building ; besides many books were de- 
stroyed, having been eaten through and through. Another nest 
also was found in a small out-building ; the insects of these two 
nests corresponded to those found in my dwellings, &c., while 
marked differences existed between the latter and 7. bellicosus. 
I regret exceedingly that the steps to prove this opinion have 
failed in the manner above stated. I hesitate not, however, to 
assert it, confirmed as it is by other observers.

The work was begun with three men at 20 minutes past 4 P.M., 
and required 24 hours to accomplish it. : 
The material was red clay, obtained about two feet below the 
surface-soil, the latter being a mixture of sand and decayed vege- 
table matter brought down from the surrounding hills. The 
surface was highly indurated, receiving a slight impression from 
a single blow of the mattock. 
The order first seen was the workers, who instantly retreated 
on exposure to the external air. They were succeeded by one 
and then another, and then many of the larger class of soldiers, 
who, rushing out in great rage with jaws extended, threatened 
vengeance on the intruders. 
The experiment of permitting them to bite was tried several 
times, when it was perceived that a drop of brownish fluid was 
exuded upon the part. The sensation was like that of a minute 
sharp-cutting instrument, the jaws moving in cross direction hke

On breaking several of the upward projections or “ turrets,” 
they were perceived to be hollow, leading into the “ dome,” and
