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



they passed solid oval frass like the furniture Termite 

 {Calofermcs domestic us). If picked up tliey discharged a 

 drop of muddy fluid from the anus, which under the 

 microscope was found to be literally crammed with 

 infusoria. 



"About December 16tli some of these Termites were 

 taken and placed in glass tubes plugged at the mouth 

 with cotton wool and kept in a closed box in the dark. 

 In some of the tubes 12 individuals and in others 24 

 were put. In a few days it was noticed that in two or 

 three of the tubes there were Termites without the 

 posterior end of their abdomen, they looked as if the 

 posterior half had been snipped off. They were alive and 

 on the wood. There was no evidence to support the 

 idea that they had been bitten. It is probable, how- 

 ever, that the condition was in some way the consequence 

 of insufficient food and moisture; for the wood that they 

 were on was too hard for them. 



''Many of the specimens preserved in spirit at this 

 time, or earlier, have compound eyes, are yellowish in 

 colour, and clearly are incipient neoteinic forms, un- 

 fortunately the exact dates at which the specimens were 

 put into spirit are not recorded on the tubes. 



" On January 2nd the following record of the tubes 

 was made : — 



" Tube 1. 19 individuals, without trace of winofs, but 

 varying in size; one is brown with brown compound 

 eyes; another is yellowish white, uniform in colour 

 except for the dark streak of the cardiac vessel, it is of 

 smaller size than the first, and its compound eyes are not 

 pigmented; the other 17 have no compound eyes, and 

 are white except where the brown colour of the intestines 

 shows through the cuticle. 



" Tube 2. 16 are alive and two are dead at the 

 bottom of the tube. They all seem to be in a bad way, 

 and to be starving, the wood appears to be too hard for 

 them. None of them have signs of compound eyes. 



" Tube 3. 18 individuals, none are yellowish or have 

 compound eyes. Their wood seems hard, but they are 

 healthy. 



" Tube 4. 11 individuals, healthy, none appear to 

 have compound eyes. 



"Tube 5. 7 individuals healthy, none appear to 

 have compound eyes.
