1896.] MR. HILL ON INHERITANCE OF ACQUIRED CHARACTERS. 785 
last-named animal he had never previously seen alive. It was 
generally black, with a white line at the angle of the mouth and 
slight white tips to the ears; nearly 3 feet in height at the 
shoulders. The curious long-haired, divaricated mane was slightly 
mixed with whitish hairs. There were also an adult pair of 
Cobus ellipsiprymnus, and two pairs of C. unctuosus, with a young 
one born in the Gardens. The Giraffe-house was unfortunately 
vacant. 
At The Hague Garden, Mr. Sclater had found little of interest 
except an example of Canis adustus, Sund., from South Africa. 
He doubted whether Dr. Mivart was correct in referring 
C. lateralis, Scl., of the Gaboon district, to the same species. 
At Rotterdam (Heer Van Bemmelen, Director) Mr. Sclater 
found a fine new Lion-house, a new set of Offices, and other 
buildings erected since his last visit. The beautiful specimen of 
Cephalophus sylvicultriz which had been figured in the ‘ Book of 
Antelopes’ (plate xii.) was still alive and in excellent condition. 
Mr. Sclater had also noticed a pair of Anoas (Bos depressicornis) 
and a young male Canis jubatus. The Heronry of Wild Herons 
in the Garden had this year contained 58 nests. 
Mr. P. Chalmers Mitchell, F.Z.S., made some remarks on a 
supposed case of Telegony, as shown by a Fox-terrier puppy which 
possessed Dachshund peculiarities, possibly due to a known earlier 
fertilization of its mother by a Dachshund. The puppy, which had 
been bred by Mr. O. H. Latter, F.Z.S., was exhibited. 
A discussion followed in which Sir Everett Millais, Mr. B. 
Tegetmeier, and others took part. The general opinion seemed to 
be adverse to the theory of Telegony. 
Mr. Leonard Hill, M.B., Lecturer on Physiology, London 
Hospital Medical College, and Grocers’ Company Research Scholar, 
gave the following account of some experiments on supposed cases 
of the inheritance of acquired characters which he had been 
carrying on :— : 
“Tt has been recorded by Brown-Sequard that after section of the 
cervical sympathetic nerve in Guinea-pigs, a droop of the upper 
eyelid is acquired, and that this droop is transmitted to the 
young. 
«This statement, at the request of the late Dr. Romanes, I have 
put to the test of thorough experimental observation. 
“In March 1895 I took six healthy normal Guinea-pigs, and in 
all divided the cervical sympathetic nerve on the left side. A droop 
of the upper eyelid was thus established, and this has persisted 
undiminished up to the present date. 
“These Guinea-pigs were allowed to interbreed. In none of their
