592 Mr. G. D. Haviland and Dr. D. Sharp on 



''On March, 17th, 1895, they reached England and 

 were sometimes exposed for brief intervals to cold, once 

 to below 45 degrees F., when they were quite helpless, 

 but soon recovered ; generally they were kept warm 

 artificially. 



" On Marcli 30th there was only one tube of them left, 

 but that had a good number of individuals in it. It had 

 frequently produced winged individuals and continued 

 to do so at intervals, till there were but few left; these 

 images could not escape through the plug of cotton wool, 

 and did not seem to live many days after they had got 

 their wings. So far there was no neoteinic individual 

 recognized. 



" On December 5th, 1895, Dr. Sharp, who then had 

 charge of them, wrote : ' The colony is producing 

 winded forms and eorgrs : where the eg'S's came from I 

 have not ascertained, they are of comparatively large 

 size ; the Termites lift them in their mouths and carry 

 them about as ants do.' " 



The specimens of this species under my charge were 

 all contained in a test tube 6 inches long, |-inch in 

 diameter. The tube contained a large splinter of the 

 wood the Ccdotermes eats, and was closed by a plug of 

 cottonwool; the Termites never attempted to interfere 

 with this plug, but kept away from it ; occasionally it 

 was taken out and a minute quantity of water was added 

 to make the atmosphere damp. The intra-tubal arrange- 

 ments of the Termites were interfered with in no other 

 way ; the tube was placed in a small card-box, packed 

 with cotton wool to keep it steady, so that the Termites 

 were not exposed to light ; during the winter the box 

 was placed in a corner of one of the apartments of the 

 new museums at Cambridge (the Bird-room), under the 

 hot-water pipes, but, notwithstanding this, it was exposed 

 to great vicissitudes of temperature. The Termites, on 

 the whole, did well, and had there been more of them to 

 start with, it is, I think, probable that the association 

 might have been maintained for a long time, instead of 

 becoming extinct in October, 189G, after nearly two 

 years of this highly artificial kind of existence. At first 

 the colony produced numerous winged individuals, and this 

 process continued for about a year ; none of the winged 

 individuals were taken out of the tube, and I think they 

 all soon died. As a result, at the beginning of the
