scientific man I have only to name casein or rennet of milk as one 

 substance that would convert it into lactic acid, the natural gastric 

 juice of the system. 



The other is Scrofula, or generally known as incipient consumption. 

 All organized bodies are composed of carbon, hydrogen, nitrogen, and 

 oxygen. This disease is produced by excess of hydrogen in the pro- 

 portion to form water with oxygen, and a deficiency of nitrogen to 

 form fibrin or proper muscular contractility. Again, not to enumerate 

 the particular remedies, I may say that all such as contain nitrogen in 

 excess and are deficient in hydrogen, of these oxalic and tartaric acid, 

 the cyanides, and ammoniacal salts, are familiar examples. Thus, Sir, 

 the great point of separation between the profession and empiricism is 

 on the subject of education, — the former holding that whatever theory 

 is followed, the practitioner must understand anatomy, physiology, 

 pathology, chemistry, and the nature and effects of medicines, the 

 action of mental influence upon disease, sufficient knowledge of collat- 

 teral sciences to judge so far as they bear upon their patients, atmos- 

 pheric influence, chemical tests, and the use of the microscope ; and, 

 in addition, their minds expanded by study, enabling them to compre- 

 hend and unravel the intricacies of a complex and difficult complaint, 

 with sufficient moral acquirement to ensure patience, long suffering, 

 forbearance, gentleness, kindness, and unflinching firmness ; and a 

 trusting confidence that He who holds the sparrow in its fall, will 

 guide their counsels and direct their skill.

This work, expected for some time, is at length hefore Us ; and, 

 though we cannot pretend now to offer such a critical examination as 

 it deserves, we are desirous of introducing it to the notice of those in- 

 terested in its subject, with such remarks as occur to us on a first 

 perusal. And first, it is quite certain we think that there is room 

 for such a work j and that, if it makes any considerable approach
