The able chemists above mentioned were, like myself, struck with the extreme purity of the hot waters that issue from the primitive rocks of the basin of Aragua. Those of Onoto, which flow at the height of 360 toises above the level of the sea, have no smell of sulphuretted hydrogen; they are without taste, and cannot be precipitated, either by nitrate of silver or any other re-agent.
In pursuing this method the psychologist takes a person called the "subject" or the "re-agent" into his laboratory, asks him to be willing to follow certain directions carefully, such as holding an electric handle, blowing into a tube, pushing a button, etc., when he feels, sees, or hears certain things; this done with sufficient care, the results are found recorded in certain ways which the psychologist has arranged beforehand.
But what makes the blood hold these nutritious principles in solution until the very instant they come in contact with the tissue they are designed to renovate, and then, as it were, precipitate them as new tissue? You say they are in chemical solution, and the substance of contact acts as a re-agent, and thus the deposit of new tissue is only in accordance with the laws of chemistry.
Are they co-ordinate as agent and re-agent; Or is the one subordinate to the other, as effect to cause, and which is the cause or ground, which the effect or product; Or are they co-ordinate, but not inter-dependent, that is, 'per harmonium præstabilitam'. Ib. p. 4.
But when you come to apply it how do you get your re-agent? There's no known method " Dr. Schermerhorn broke in: "Ach, it iss that I haf perfected. Pardon me, my boy, it iss the first I haf worked from you apart. It iss for a surprise. I haf made in small quantities the missing ingredient. It will form a perfect interruption to the current. Now we go "
I've found it," he shouted to my companion, running towards us with a test-tube in his hand. "I have found a re-agent which is precipitated by hoemoglobin, and by nothing else." Had he discovered a gold mine, greater delight could not have shone upon his features. "Dr. Watson, Mr. Sherlock Holmes," said Stamford, introducing us.
That carbonate of lime and phosphate of lime are precipitated or assimilated from the plasma to form bone, is admitted by all physiologists. That the carbonates and phosphates already deposited act as the re-agent to precipitate fresh supplies from the plasma is not a demonstrated fact, but may be inferred. So also with the other tissues.
