down into the fauces, larynx, trachea and larger and 
smaller bronchi. As soon as they reach the fauces there 
is a burning heat and irritation in the parts that excite 
severe coughing. 
If the parasite makes its way into the smaller bronchi 
and air cells, asthmatic symptoms of a distressing charac- 
ter often supervene. 
The cough is short and somewhat painful, and the 
invaded surfaces feel irritated and hot. The cough 
- raises but a small quantity at a time and relieves the irri- 
tation and itching but a few moments. Whenever the 
parasites are developing rapidly on the velum palati, 
most intense paroxysms of coughing are excited, which 
are long, persistent and painful, and sometimes are 
accompanied by severe spasms of the epiglottis. Often 
an irritation and itching will be felt on one side of the 
throat only, exciting constant desire to cough. 
This disease belongs to those that may be transmitted 
from one individual to another, though the transmission 
is not very readily accomplished. In working very closely 
over about sixty cases of the disease, examining the sputa 
under the microscope for many hours together in each 
instance, and in several severe attacks devoting days to 
the examination, Dr. Salisbury took the disease six times 
and in two instances transmitted it to his family. 
He usually began to feel symptoms of the presence of 
the parasites in from four to eight days after beginning 
to treat a case, taking the precaution to inhale a solution 
of crystallized carbolic acid, one drachm to the pint of 
water, every two or three hours, and to take twenty 
drops of tincture ferri-chloride in a tumbler of water 
two hours after each meal. 
I have found inhalation of menthol and camphor and 
at times a saturated solution of benzoate of soda used 
with a nebulizer would do the most good, while the men-
