NEW SUPPOSITORY INTRODUCER. THIS instrument is very simple in construction, being merely a solid vulcanite bar conveniently curved, and having a spoon-shaped recess at the apex just large enough to receive and hold firmly an ordinary suppository. Thus charged, it serves not only to introduce, but to maintain the
suppository in contact with the surface it is desired to affect during solution, and afterwards of absorption or continued application, as may be desired. The instrument has been made for me by Messrs. John Richardson and Co., Leicester, Limited, and answers perfectly. Mountsorrel, April,
