of bleaching by means of red lead, so easy, so speedy, so 
practicable, and so economical, that no one who has tried 
it, would hesitate for a moment to prefer it to the bleach- 
ing by manganese, even if the latter substance could be 
obtained for nothing. I have had bleached under my 
own inspection by this process, more goods in a week, 
than any manufacturer of cotton goods of whatever spe- 
cies in this country, manufactures in a year. Yet bleach- 
ing by manganese, imported at an extravagant rate from 
Great Britain still continues in use, even among the best 
informed manufacturers of cotton articles in this country.. 
However as the process is my own, I now give notice that 
I will take out a patent for it ; and then perhaps, it will be 
thought of some value, when some value is paid for the 
liberty of using it. Having turned my attention early, to 
anatomy and physiology, and to medicine also, as well as 
chemistry, I have for many years practised among my 
friends, among the poor, and wherever my neighbours of 
the medical profession thought fit to consult me upon any 
case, curious or difficult. But as I have never directly or

my patients, to advise a physician to be called in because 
my prescriptions really do no good for want of faith in 
their efficacy, until the patient has to pay for them. Some 
physician of eminence in England, I forget who, is said, 
always when he took medicine for his own indisposition, 
first of all to take a guinea out of his right hand pocket 
and put it into his left hand, as a sum to be religiously 
spent in some act of charity ; otherwise he would have 
doubted the efficacy of his own advice. Indeed it is true 
universally, that the world never feels grateful to those 
who benefit them gratis : they only are respected, who 
setting a proper value on their services exact the highest 
price for them. People take for granted from an intimate
