This observation together with his own interest in science led him, in September of his first year, to institute a series of lectures for the benefit of the servants and employes of the mission compound “in hopes of waking up their dormant minds and accustom them to think, and so be a little benefitted by the preaching on the Sabbaths; as well as to impart useful information and to set before them the great proof of the existence and wisdom of the Creator, a fundamental truth all Buddhists deny.” The doctor was to furnish the outlines and perform the experiments while Mr. Caswell, experienced in the language, was to do the talking. There was a fair equipment at hand: chemicals, a magnetic machine, a globe, a set of physiological and hygienic charts and a skeleton.
The first lecture was on the digestion of food and the effects of alcohol on the stomach. The audience showed their attention and interest by responding with questions. After the lectures on physiology came several on astronomical topics such as the eclipse of the moon, phases of the moon and relation to the tides; then followed several on the gases. On the occasion of the first lecture on the gases, it so happened that Godata, a priest from Chao Fah Yai’s watt, happened to call on Mr. Caswell and was invited to witness the experiment. The demonstration opened a new world for him. What he saw was too wonderful to keep to himself; he spread abroad his report and the effect was immediate.
The first to respond was Prince Ammaruk, the favourite son of the king, who requested the privilege of watching the doctor create the wonderful “winds.” On the day appointed for the special experiment, Chao Fah Yai sent a request for Dr. House to accompany him that evening to call upon a brother prince who was quite ill. In reply the doctor explained his engagement for the evening, but offered to make the call after the demonstration, and suggested that the Priest-Prince might himself like to witness the experiment. To the doctor’s surprise, the Priest-Prince came early in the afternoon to take the doctor to see the patient, so that they might have the whole evening free for the experiments. At the palace, Chao Fah Yai explained the evening’s entertainment to the royal physician (a brother of the king) who promptly invited himself. By arrangement with Prince Ammaruk several others were to come, so that at the appointed time the small house was filled with nobles and princes, and the verandah with their servants. Fortunately the experiments went off successfully; oxygen was generated and iron was burned in the oxygen; hydrogen was generated from water and exploded in combination with oxygen. Chao Fah Yai was particularly enthusiastic, and called in from the verandah some of his men to see the wonders, and himself volunteered to explain the facts to them.
The series of lectures awakened widespread interest among the progressive nobles. Dr. House became a notable in their esteem. Nearly all of the group who were present on that evening were amateur scientists; they had the air pump, the electric machine and other physical apparatus, but of chemistry they had no idea. Shortly after this Chao Fah Noi, who had been keeping aloof from foreigners, sent a request for Dr. House to spend the evening at his palace and instruct him in the making of gases. How long the series of lectures continued is not apparent; the journal continues reference to them while they are novel, but they apparently continued throughout that winter. Other subjects named were “The Weight of the Atmosphere,” “The Barometer,” “Heat,” “The Oxyhydrogen Blow Pipe,” “Carbon and Carbonic Gas,” “Electro-magnetic Telegraph,” and “Electricity.” The original purpose of instruction for the servants was outgrown, and week after week one or more of the nobles who were dabbling in science were present with their ubiquitous train of servants. From this time on the journal indicates that the doctor’s instruction in the Bible classes took the form of “Evidences of Natural and Revealed Religion.”
The popular interest, however, was directed towards a particular subject, the skeleton. Very quickly news of this strange possession spread abroad, and every few days in season and out of season visitors would call and, scarcely able to restrain their inquisitiveness during the preliminary courtesies, hasten to request a sight of the skeleton. Even some of the ladies became interested in this curiosity; and one day a woman of rank, with half a dozen attendants and a train of servants, came with a request to see the skeleton. Long after local curiosity had subsided, chance callers from distant provinces would come to see this object of nation wide gossip.
Very remarkable, the skeleton itself did not seem to make so profound an impression upon these minds as the “argument from design” which their instructor deduced from the human anatomy to prove the existence of a Creator. Female curiosity also called for demonstrations with the electrical machine. During the reign of the old king some of the ladies of the palace had a prince arrange for Dr. House to bring to the prince’s palace the machine which could make “fi fah” (fire from the sky), that they might see the marvel. The doctor, of course, was not permitted to enter the presence of the king’s women, so he had to instruct the prince in the method of operation.
BOND OF INTEREST
An unexpected result of these lectures was that a bond of mutual interest was established between Dr. House and this group of progressive nobles, the very party which in a few years dominated the new government of Siam. It would be interesting for one who knew the official entourage of King Mongkut to note how many of his supporters were included in this number who made Dr. House their friend because of his interest in science. Since Siamese noblemen were known by titles rather than by family names and since these titles change through elevation to higher rank only one acquainted with a person at a particular rank could identify these men with accuracy.
However the following are frequently mentioned in Dr. House’s journal as showing a friendly attitude to him, and most of them interested in Western science. In the régime which began in 1851 his friends were: the king, the vice-king, the prime minister, the commander-in-chief, the minister of foreign affairs, the minister of home affairs, the treasurer of the kingdom. In the régime of Chulalongkorn, which began 1868, his special friends were: The second king, the regent, the minister of foreign affairs, the master of the mint, the commander-in-chief, and the court chaplain. Besides these were several princes and nobles who did not occupy particular offices. Several of these men had primitive laboratories or workshops for experiments.
The series of lectures started such a revival of interest in scientific matters among them that Dr. House soon found himself the frequent host of several princes and nobles, seeking instruction in all sorts of subjects; and he was on various occasions invited to their shops to inspect their work or elucidate some obscure difficulty, as though he were a peripatetic professor. He was even seriously troubled by the borrowing of books and instruments which they were not all punctilious to return. Moreover, he found himself an agent of some of these men, ordering machinery and supplies and tools from America for their use.
