Experiment 4. Fourteen Newts were collected and on April 30th 

 seven were placed 10 yards away at Z, and seven 5 yards away at Y. 



Result. No Newts had returned by the next day, but seven were 

 recovered on May 4th and four more on May 14th, making 11 out 

 of the 14. In this experiment I did not take the precaution of 

 making the two lots distinguishable when marking them, so that 

 I could not refer the animals recovered to their respective 

 batches. 



Experwient 5. Six natives were collected and set loose on 

 May 12th, 10 yai"ds away at Z. 



Result. None had returned on the 13th, three were recovered 

 on the 14th. On May 29th the fourth returned, and on June 1st 

 the fifth was taken. 



Experiment 6. On May 30th six natives were placed at X, 



5 yards from the pool. 



Result. On June 1st five were recovered. 



After this date the approach of summer weather maxie further 

 work for the year prejudicial to reliable results. 



Homing Experiments, 1911. 



I took the precaution of beginning earlier in the spring this 

 year, and the following few experiments which I was able to carry 

 out shew that a greater proportion of imported Newts was 

 recovered. 



Experiment 7. On March 26th six natives were set loose, 12 

 yards away from the pool along the incline at X. 



Result. Next day none had returned. Two were caught on 

 March 29th, one on March 30th, one more on April 5th, and the 

 fifth, and last to be recovered, on April 9th. 



Experiment 8. On April 2nd six natives were set loose along 

 the same incline but 24 yards from the pond. 



Result. The next day the only successful animal was recovered. 



Resuming with imported Newts, the following experiments 

 were made : — 



Experiment 9. On April 2nd six imported Newts were placed 



6 yards from the pond, along the incline at X, six more 12 yards 

 away along the same incline. 



Result. The next day none had returned. On April 7th one of 

 the 6-yards' lot was obtained and one more on the 12th. Three 

 of the 12-yards' batch were obtained, one on April 5th, one on 

 the 7th, and the third on the 12th. 



Experiment 10. On April 16th 24 imported Newts were set 

 loose in the neighbourhood of the pond in four Batches : — 



A. 6 were placed 5 yards along the incline X.
