In connexion with this matter it is to be noted that the sperm of one drone (her only mate) is retained in an internal sac or pouch, alive and active, in the queen bee, for some four or five years, and is used by her in successive seasons for fertilizing her eggs. Similarly it is recorded by the late Lord Avery that a queen ant kept by him for fourteen years, without access to a male ant, retained to the end of that period the power of producing eggs which developed into worker ants. He concluded that the sperm received fourteen years before by this queen from a male ant remained all this time alive and ready for use in her sperm-receptacle or sac, since it has been shown that unfertilized eggs in these and allied insects produce only drones (males).

Many strange and unwarranted beliefs persist because mankind prefers to accept an astonishing assertion as true rather than take the trouble to see whether it is so or not. Thus all antiquity and the later learned world wrangled about the very existence of Homer's city of Troy, until Schliemann said, "Don't talk! Dig!" and with childlike simplicity and directness uncovered ancient Troy. Thus the belief as to St. Swithin and his forty days of rain has been shown by the simple examination of the actual records of rainfall to be very far from the truth, since, though we often have a wet period in July and August, St. Swithin's Day is nearly as often free from rain in a wet season as the reverse. Forty days of rain very rarely indeed, in the South of England, have followed a wet St. Swithin's Day. The most amusing instance of the pricking of one of these bubbles of belief arose from the inquiry by some of the sham philosophers at the Court of King Charles II as to how it comes about that if a jar holding water be weighed, and then a live fish be placed therein without spilling any of the water, and the jar, with the fish and the water in it, be again weighed, there is found to be no increase in the observed weight. King Charles, it is said, made a bet that this was not so, and that there was nothing to explain. He referred the matter for decision to the newly founded "Royal Society for the Promotion of Natural Knowledge," which at other times he had asked to give him information as to the magic properties of the unicorn's horn and the cause of the movements of the recently imported "sensitive or humble plant." The believers in the marvellous disappearance of the weight of a fish placed in a bowl of water held forth at great length and gave ingenious reasons as to why this is so. But the King said, "Don't chatter; make trial!" And the weighing was done, in the King's presence, by some of the Fellows of the Royal Society. It was found that the weight of the jar with its contained water was increased when the fish was placed therein by exactly the number of ounces which the fish weighed when placed separately in the balance. So the King won his bet, and the sham philosophers were silenced. The whole spirit of science, as contrasted with that of superstition and ignorance, is summed up by the Royal Society's motto, "Nullius in verba" (on no man's assertion!), and the King's command, "Don't chatter; make trial!"


CHAPTER XLI
HOW TO PROMOTE SCIENTIFIC DISCOVERY
BY MONEY

THE fact that five years ago Mr. Otto Beit, the brother of the late Mr. Alfred Beit, not only carried out the latter's intention of giving £50,000 to the promotion of research in connexion with the study of disease and the mastery of its causes, but added £150,000 on his own account to the amount originally proposed, produced great satisfaction among scientific men, and also in that large body of the public which, at the present day, understands something of the importance to the community of the minute and thorough study of disease, of its mode of access to man, and of the possibilities, which every day become brighter and clearer, of getting rid of it altogether. All honour and gratitude are due to Mr. Beit for his generous gift and for his wise appreciation of the good which can be done by proper application of such a fund. I have reason to know and to value the large-minded interest in science which was shown by the late Mr. Alfred Beit, since he gave me £1000, some twelve years ago, towards the expenses of expeditions which I was organizing for the investigation of the natural history of Lake Tanganyika,—expeditions which have yielded important scientific results, and have but recently exhausted the fund then collected.

It has often occurred to me that wealthy men who wish to devote large sums of money to the promotion of scientific research find difficulty in carrying out their intentions, owing to the fact that they do not know enough about the methods and conditions of scientific discovery to enable them to form a definite independent judgment as to how to assign their money, so as to make sure that it shall really be employed in the most effective way towards the end they have in view—namely, the increase of scientific discovery. They naturally have some doubts as to whether the old (or even the new) Universities can help them as trustees of the money when they see the importance attached by the former to antiquated methods of teaching and examination and observe their traditional cultivation of certain favoured studies, with a minimum of activity in research and discovery. They mistrust special societies or individuals as advisers in the matter, and sometimes finally spend the money which they had destined to be the means of furthering scientific discovery upon a costly and ill-considered architectural monstrosity dedicated to science, but of little help to its progress.

In past times various schemes have been adopted by benevolent men for bequeathing or giving their money so as to promote scientific discovery. Very generally there has been a certain amount of confusion between two distinct purposes—namely, that of creating new knowledge (the discovery of previously unknown things and new processes), and that of spreading existing knowledge amongst an increased proportion of the community. An admirable endowment for the latter purpose is that of Mr. Smithson, a member of the family of the present Duke of Northumberland, which was refused by the British Government for peculiar reasons, and conveyed by that gentleman to trustees in the United States of America about a hundred years ago, where the Smithsonian Institution has vastly aided the spread of science. Another valuable endowment which has been administered by special trustees for a still longer period is that of the celebrated physician Radcliffe, to whom we owe the scientific and medical library, an astronomical observatory, and travelling fellowships in the University of Oxford. The greatest sum dedicated to scientific research in England of late years is the noble gift of a quarter of a million sterling made by Lord Iveagh to the Lister Institute of Preventive Medicine. There have been not a few generous donors of smaller sums for like purposes.

An inquiry was set on foot a few years ago in America in order to obtain the opinions of those who had experience of scientific research and the institutions intended to promote it in different countries, as to the best methods to adopt in order to effect such promotion. I do not know whether any report was published, but I remember that I was consulted on the subject by the late Professor Simon Newcomb, a foreign member of the Royal Society and one of the most distinguished scientific discoverers in the United States. I am quite sure that no general agreement or conclusion on the subject has been arrived at. So far as I can see, whenever any high-minded philanthropist desires to devote in this country a large sum of money to the promotion of scientific discovery, he is liable to come under the influence of highly respectable and eminent persons who, although they have no acquaintance with the nature of scientific discovery and the way in which it actually takes place, do not hesitate to fix up a scheme based on some antiquated and mistaken model, which is accepted with simple faith by the benevolent donor.
