the directorship of the Jardin d'Acclimatation, then just 

 founded in Paris, were due the abolition of the rule 

 which required that all visitors should be provided with 

 a fellow's order^ and the policy of admitting the public 

 on Mondays, and children at any time for sixpence each. 

 On Mr. Mitchell's retirement, Dr. Philip Lutley Sclater 

 was elected to the post of secretary, which he held until 

 1901. During the lengthy period that he held office 

 many changes were effected in the gardens, the most 

 important being the erection of the Antelope House 



office of secretary for a short period, but at the following 

 annual meeting, on a vote of the fellows, the present 

 secretary, Dr. P. Chalmers Mitchell, was elected to the 

 post. Just prior to the retirement of Dr. Sclater some 

 dissatisfaction had been expressed by a number of 

 fellows with the housing conditions in the gardens, and 

 the new secretary was soon at work, carrying out 

 various improvements which gave immediate satisfac- 

 tion to the fellows and public.

 1901 Dr. Sclater retired after serving the society for 

 forty-three years, a period during which the society 

 occupied a very high position in the scientific world. 

 On his retirement his son, Mr. W. L. Sclater, held the

with various small cages, and giving their inmates more 

 exercise, Dr. Chalmers Mitchell, in spite of some 

 opposition, insisted that many of the animals, which 

 hitherto had been confined all the year round in very 

 hot cages, should be given access to the open air. It 

 was then the general belief that most of the creatures 

 coming from the tropics should be kept very warm, 

 and consequently their housing conditions were deter- 

 mined almost solely by considerations of temperature. 

 Now visitors to the gardens in winter may see a host 

 of tropical animals in the open, a change of policy 

 which has had the effect of improving greatly the
