ailment may be made on the principle or law that likes may be 

 cured by likes; as before stated, given several cases of Pneumonia, 

 Bronchitis, or Pleurisy, no two cases will present an exactly 

 similar totality of symptoms, therefore, though generally speaking, 

 the names given to these diseases may be useful, they do not furn- 

 ish any relial)le data whereupon a doctor razy select a remedy; 

 every case must be taken as it is found and the guide for the 

 selection of the drug must l^e the aggregate of the symptoms pre- 

 sented; in conclusion the law of healing (Therapeutic Law) 

 includes two classes of symptoms: First. — The symptoms out- 

 wardly exhibited and inwardly felt by the patient. Second. — The 

 symptoms produced in a healthy subject by a drug; provided 

 always that the symptoms which the drug produces are similar to 

 those of the patient, under which circum.stances the former will 

 relieve and remove the latter. So far our aim has been to make 

 clear the system of medicine in accordance with which the ailments 

 of a patient may be cured through the instrumentality of a remedy 

 in the form of drugs; but it must be distinctly understood that as 

 with the human subject, so, and indeed more also, with horses it 

 frequently happens that circumstances calling for very careful 

 attention arise in which the science of treating animals by means 

 of drugs (therapeutics) will not meet the case adequately, or, 

 indeed, at all; for instance, a horse meets with an injury due to 

 an unavoidable accident, or he has his foot severely pricked while 

 being shod; again, you may own a mare that is with foal, which, 

 by reason of its having got into an unnatural position cannot be 

 born w'ithout assistance; these are cases calling for operative sur- 

 gery; and while it is not at all improbable that the condition of 

 the patient may be such, as a consequence of these circumstances 

 to require the administration of drugs by way of assistance, the 

 difficulties could not be got over by drugs alone; operative sur- 

 gery here would be the chief factor in the course of treatment; 

 therefore it must not be imagined that cases such as these calling 

 for mechanical interference can be cured by the administration of 

 drugs only. Again, there are certain diseases which owe their 

 origin to parasites, which are found both in the body and upon it 

 externally; lor the removal of these chemical or mechanical means 

 must be adopted; for the destruction of these animal or vegetable 

 organisms the homoeopathic law is not applicable, though there is
