38 Observations on the Tellovj- Fever. 



considerable number of debtors in an adjoining build- 

 ing. The usual number of patients remained in the 

 hospital, and more than 200 pensioners in the alms- 

 house. More than 2000 emigrants, lately arrived from 

 the island of St. -Domingo, resided, at the same time, 

 in different parts of the city. 



Notwithstanding these circumstances, all the pri- 

 soners in the jail, the patients in the hospital, the pen- 

 sioners in the alms-house, and the emigrants from St.- 

 Domingo, residing in difierent parts of the city, escap- 

 ed the disease, though they were surrounded, for more 

 than two months, by the sick, the dying, and the dead, 

 and breathed the same air as the rest of the inhabit- 

 ants, with the exception of that in immediate contact 

 with the sick. 



If the disease had depended either on putrid exhala- 

 lations, or a morbific constitution of the atmosphere, 

 nothing, short of a miracle, could have preserved them 

 from the disease. 



If, in addition to these facts, we advert to the cir- 

 cumstance of the disease having been prevalent in 

 Grenada, and several other West- India islands, some 

 months before it made its appearance in Philadelphia, 

 in the year 1793, of which we have the most positive 

 testimony, I flatter myself you will be convinced, that 

 this disease neither originates from domestic causes, 

 nor from any change in the constitution of the at- 

 mosphere, but is to be looked for in a foreign source.
