　　If the old maxim that the customer is always right still has meaning, then the airlines thatply the world’s busiest air route between London and Paris have a flight on their hands.

　　The Eurostar train service linking the UK and French capitals via the Channel Tunnel iswinning customers in increasing numbers. In late May, it carried its one millionth passenger,having run only a limited service between London, Paris and Brussels since November 1994,starting with two trains a day in each direction to Paris and Brussels. By 1997, the companybelieves that it will be carrying ten million passengers a year, and continue to grow from there.

　　From July, Eurostar steps its service to nine trains each way between London and Paris, andfive between London and Brussels. Each train carries almost 800 passengers, 210 of them infirst class.

　　The airlines estimate that they will initially lose around 15%-20% of their London-Paristraffic to the railways once Eurostar starts a full service later this year ***1995***, with 15 trains aday each way. A similar service will start to Brussels. The damage will be limited, however, theairlines believe, with passenger numbers returning to previous levels within two to three years.

　　In the short term, the damage caused by the 1 million people-levels traveling betweenLondon and Paris and Brussels on Eurostar trains means that some air services are alreadysuffering. Some of the major carriers say that their passenger numbers are down by less than5% and point to their rivals-Particularly Air France-as having suffered the problems. On theBrussels route, the railway company had less success, and the airlines report anything fromaround a 5% drop to no visible decline in traffic.

　　The airlines’ optimism on returning traffic levels is based on historical precedent. BritishMidland, for example, points to its experience on Heathrow Leeds Bradford service which sawpassenger numbers fold by 15% when British Rail electrified and modernized the railway linebetween London and Yorkshire. Two years later, travel had risen between the two destinationsto the point where the airline was carrying record numbers of passengers.

　　Without regular supplies of some hormones our capacity to behave would be seriouslyimpaired; without others we would soon die. Tiny amounts of some hormones can modifymoods and actions, our inclination to eat or drink, our aggressiveness or submissiveness,and our reproductive and parental behavior. And hormones do more than influence adultbehavior; early in life they help to determine the development of bodily form and may evendetermine an individual’s behavioral capacities. Later in life the changing outputs of someendocrine glands and the body’s changing sensitivity to some hormones are essential aspectsof the phenomena of aging.

　　Communication within the body and the consequent integration of behavior wereconsidered the exclusive province of the nervous system up to the beginning of the presentcentury. The emergence of endocrinology as a separate discipline can probably be traced tothe experiments of Bayliss and Starling on the hormone secretion. This substance is secretedfrom cells in the intestinal walls when food enters the stomach; it travels through thebloodstream and stimulates the pancreas to liberate pancreatic juice, which aids indigestion. By showing that special cells secret chemical agents that are conveyed by thebloodstream and regulate distant target organs or tissues. Bayliss and starling demonstratedthat chemical integration could occur without participation of the nervous system.

　　The term “hormone” was first used with reference to secretion. Starling derived the termfrom the Greek hormone, meaning “to excite or set in motion. The term “endocrine” wasintroduced shortly thereafter “Endocrine” is used to refer to glands that secret products into thebloodstream. The term “endocrine” contrasts with “exocrine”, which is applied to glands thatsecret their products though ducts to the site of action. Examples of exocrine glands are thetear glands, the sweat glands, and the pancreas, which secrets pancreatic juice through aduct into the intestine. Exocrine glands are also called duct glands, while endocrine glands arecalled ductless.
