Dr. Broughton, in his Thesis, says: "In all the cases of disease in which I have seen or heard of the exhibition of the web, no sensible, or at least no uniform, operation could be observed. Some patients were sensible of none, others of a slight sudorific, and some a nauseatic effect; and one or two thought it proved cathartic after remaining in the system for the space of twelve or fifteen hours. These accounts being so incorrect and various, I determined to ascertain (if possible) the correct operation by giving the web to healthy persons." "I found from these experiments that the operation of the web appeared principally to be upon the arterial system; and perhaps in less time than any article already known: the force and frequency of the pulse being uniformly reduced in some cases ten, in others fifteen strokes in a minute; and in one case, the pulse, from being strong and full, became soft, small, and very compressible; all which operation took place within the space of two hours, after which time the artery gradually regained its former force and frequency. This has been the only invariable effect I could observe, all others appearing but anomalous." Dr. Thacher cites the following case from a paper of Dr. Jackson's: "W. Sands has been afflicted for many years with a distressing asthma, which has proved fatal to his father and two sisters. The complaint being hereditary, and aggravated by malformation of the thorax, no remedy gave any permanent relief, nor did change of climate procure any alleviation of symptoms. For a considerable time back he has never been able to lie down in bed on account of a sense of suffocation, but is obliged to be supported half sitting by pillows, and is seldom able to sleep. He swallowed nearly a scruple of the spider's web, he swallowed it at bed time, and to his utter astonishment enjoyed sound and uninterrupted sleep all night; a blessing to which he had been an entire stranger above six years. Since he began with the cobweb thinks his health is improved; the cough has certainly abated, but whenever the remedy is omitted the complaint returns." Dr. Oliver found that "by the use of this remedy a patient laboring under organic disease of the heart and hydrothorax obtained great relief and refreshing sleep, who had not before slept for three nights. Another, under similar affection, experienced uncommon relief from the same prescription. To one suffering much pain from cancer it afforded ease and comfortable sleep. A patient in phthisis pulmonalis being affected with distressing agitation of mind and nervous irritation, it answered like a charm, and soon induced great sleep like a moderate dose of opium."
