In order to ascertain the truth by a personal examina- tion, some scientific gentlemen were commissioned by the editor of the Lancet to conduct certain experiments on animals at the establishment of Mr. Langdale, of 72, Hatton-garden, who was the first manufacturer of the purified oil. Some investigations were hence entered upon by this commission on Wednesday, Nov. 26th last, with results which we proceed to describe. The animals experimented upon were a dog, a eat, and four rats. * * * " Experiment 1.—A young shepherd's dog was held whilst a drachm of Mr. Langdale's purified oil was poured down his throat. No convulsions were manifested, and the dog did not appear to lose consciousness. In less than a quarter of an hour the dog was free from any distressing inconvenience, and able to walk about as usual. " Experiment 2.—A rat was held whilst four drops of Langdale's Oil of Bitter Almonds wen dropped into the mouth. This dose appeared to have very trifling effect. * * * In a few tninntes ao person could have detected that it had been the subject of an experiment. - Kxtkuimknt 3.—A rat was held whilst four drops of the ordinary commercial Essential Oil of Almonds were given. Violent spasms ; died in six minutes and a half. I'.\1r.1; 1 m i n r 4.—To another rat, larger, four drops of ordinary commercial Oil of Almonds were given. * * * Spasmodically convulsed ; in fifteen minutes dead. - ExPEBI mi nt 5.—A cat was held whilst half a drachm of Langdale's oil was poured down its throat. In four minutes from the administration of the oil the cat had wholly recovered. ** * M The instances above cited have proved, that of Langdale's Purified Essential Oil of Almonds, one drachm administered to a middle-sized dog, half a drachm to a cat, and four drops to a rat, were incapable of destroying life ; whilst four drops of the ordinary Essential Oil of Almgndfl killed a rat in two instances. u Betides the invaluable advantage of having Langdale's Oil of Almonds pure, the flavour is far more delicate than that which is commonly sold in the shops as the Essential Oil of Almonds, it being free from the metal-like bitter taste which is imparted to the latter by
