Small brown glass bottle with cork stopper and paper label. Containing approximately 1/4 ounce of Alypin. A substance as toxic as cocaine but reserved for use in surface application to mucous membranes. Its correct name is amydricaine. It is in the field of opthalmology in a 2-4% solution, but it does not produce midriasis or disturbance of accomodation. In nose and throat work a solution of 5-10% may be employed, and in neurology a 1-4% solution. Its exact uses are unknown - though it thought that it may be used to create a local aneasthetic reaction similar to other members of the 'caine' class of drugs.
