No other journal can match Anesthesia & Analgesia for its original and significant contributions to the anesthesiology field. Each monthly issue features peer-reviewed articles reporting on the latest advances in drugs, preoperative preparation, patient monitoring, pain management, pathophysiology, and many other timely topics. Backed by internationally-known authorities who serve on the Editorial Board and as Section Editors, Anesthesia &Analgesia is your gateway to everything that is happening in anesthesia and 14 related subspecialties: Analgesia; Ambulatory Anesthesia; Anesthetic Pharmacology; Cardiovascular Anesthesia; Critical Care and Trauma; Economics, Education, and Policy; Neurosurgical Anesthesia; Obstetric Anesthesia; Pain Mechanisms; Pain Medicine; Pediatric Anesthesia; Regional Anesthesia; Patient Safety; and Technology, Computing and Simulation.

It is known that the nearest point at which an object can be seen distinctly gradually recedes with advance in age and that this recession in the near point of distinct vision varies so regularly as one grows older that it may be used in determining the age of a person. Figures such as the following are reported in the literature: At 10 years of age the near point of distinct vision is 7 cm. ; at 20 years, 10 cm. ; at 30 years, 14 cm.; at 40 years, 22 cm.; at 50 years, 40 cm.; at 60 years, 100 cm., and at 70 years of age all power of accommodation has been lost. At 40 or 50 years of age this lengthening of the near point of distinct vision obtrudes itself on one in the use of the eyes for near objects, reading, for example, and it becomes necessary

1. The irritability of Mimosa pudica rises rapidly during the first part of the morning, remains high throughout the daylight hours, and falls gradually during the night to a minimum around daybreak. 2. If plants are kept under continuous illumination for 24 hours, irritability does not fall during the night period as normally occurs but remains at the high daytime level. 3. If plants are kept in the dark for 24 hours, irritability does not rise during the daytime period as normally occurs but remains at the low nighttime level. 4. It is concluded that the increase in irritability during the day is due primarily to the effect of light. 5. Other investigators have found contrary to our observations that the irritability of Mimosa is lowest in the daytime and highest in the night. This contradiction in results is attributed to the use by other observers of an improper criterion and method for determining irritability.
