THE LOCOMOTION OF SERPENTS. 
To the Editor of The Journal of Science . 
Sir,— -It seems to me that the locomotion of serpents has not 
been sufficiently studied. Is it not probable that new light might 
be thrown on this subjedt by the use of the instantaneous photo- 
graphic revolver ? My reason for calling the attention of your 
readers to this matter is that a belief prevails in South Africa, 
and elsewhere, that certain snakes roll along like a hoop. A 
young man, just returned from the Orange Free State, tells me 
that he has witnessed this phenomenon ; but such a mode of 
travelling seems so unlikely that I am exceedingly sceptical, and 
should like further evidence. — I am, &c.,

ANTI-VIVISECTIONIST DOCTORS. 
To the Editor of the Journal of Science . 
Sir, — I should advise all medical and other scientific gentlemen 
who may find it their duty to watch or oppose the proceedings at 
Anti-Vivisedlion meetings to insist upon learning the qualifica- 
tions of “ dodtors ” brought forward to declare experiments upon 
animals useless. I have heard it hinted that some of these 
worthies hold diplomas not recognised in the United Kingdom. 
— I am, &c. 
Lynx.
