The movement against the practice of Vivisection is by no
means limited to England. The Pennsylvania Society for Prevention of Cruelty to Animals send us the history of their Bill " For the Prevention of Oruel and Unnecessary Experiments upon Animals," which was introduced into the Senate on February 23rd of the current year, and eventually lost at the third reading (in conse- quence of the opposition of the College of Physicians) by a majority of twenty-five to fifteen. The Society, we learn, highly approves of Lord Carnarvon's Bill now before the British Parliament, though they are of opinion that its provisions are scarcely sufficiently stringent. We trust they will succeed as they desire in passing a similar measure in Pennsylvania, extending the exemption clause to horses, asses, and mules.
