PUBLIC IGNORANCE AND QUACK INGENUITY. 
To the Editor of the 'journal of Science. 
Sir, — A quack who has his head-quarters near Westminster 
Bridge has an ingenious method of beguiling the public. He 
tells his hearers that if a person affected with incipient con- 
sumption blows through a glass tube into water it will at once 
turn milky, and invites them to make the trial. As the liquid 
which he offers is lime-water, the result follows as a matter of 
course. He then adds a few drops of his medicine (containing 
some acid) to the water, when the cloudiness at once disappears. 
This he argues is a proof that the same remedy will eradicate 
consumption from the human system. Multitudes of those 
present believe him, arid buy his secret remedy. — I am, &c., 
A Student. 
REPLY TO “ TRUTH SEEKER.” 
Your letter anent Mr. Tennyson does not fall within our com- 
petence. We admit that he is no friend of Science, but we 
cannot, on that sole ground, defend every person and every thing 
he may attack. If he has libelled Medicine and Free-Thought, 
both have established organs and writers competent to take up 
their respective causes. 
The Editor of the Journal of Science.
