40 Observations on the Telloiv- Fever, 



or attendants, in the clean and airy wards of Haslar 

 hospital, by those brought from on ship-board into 

 that place. 



A siniilar fact is related by Sir John Pringle, in 

 consequence of the infection of the jail-fever from 

 certain prisoners, brought into court at the Old-Bai- 

 ley, in the year 1750. Four of the bench, seve- 

 ral of the jury, and a considerable number of otlier 

 persons, died, in consequence of having received the 

 infection, without communicating it to others. 



The late Dr. Thomas Bond, of Philadelphia, in an 

 introductory lecture, delivered at the Pennsylvania 

 hospital, on the 3d day of December, 1766, and re- 

 corded on the minutes of that hospital, relates the fol- 

 lowing facts, in proof of the power of fresh air and 

 cleanliness, in destroying the contagion of the ship- 

 fever. 



" I lately (says the doctor) visited an Irish pas- 

 senger-vessel, which brought the people perfectly 

 healthy, until they came into our river. I found 

 five of them ill, and others unwell, and saw that the 

 fumes of infection were spreading among them. I, 

 therefore, ordered the ship to be quarantined, and 

 to be well purified with the steams of sulphur, and 

 with vinegar; directed the bedding and clothing of 

 the people to be well washed and aired, before any 

 person should be permitted to land out of her ; after 

 \\ hich I advised separating the sick from the healthy.
