196 Dairy Management. 



worthy of remark that this oil is held in the greatest esteem for 

 pulmonary complaints ; next to this, and almost in equal repute, 

 is pure olein. 



From what has been premised it will be found that from con- 

 sideration of the symptoms of pleuro-pneumonia I was led to 

 suppose an abnormal consumption of the elements which support 

 respiration, I have sought to meet this by a supply of food par- 

 ticularly rich in such elements, and in a form most available for 

 their purpose. My observations on the effects tend to confirm 

 my opinion that by this means I supply in food what would 

 otherwise be abstracted from the system with greater labour to 

 the organ and with impoverishment, thereby weakening the 

 ability to resist disease. I am therefore encouraged to offer it 

 for the consideration of those who give their attention to patho- 

 logical chemistry. 



If any owners of cattle should adopt my treatment I urge the 

 most scrupulous attention to the treatment here prescribed for 

 the sick animal. I am clearly of opinion that one of the animals 

 which died might, by a greater observance of this, have been 

 restored. 



In the course of the foregoing observations I have made fre- 

 quent allusion to Lehmann's ' Physiological Chemistry.' About 

 a year since I obtained this work on loan for a short time from a 

 member of the Pharmaceutical Society. A perusal of such por- 

 tions as seemed likely to afford me the particular information I 

 was then in quest of, disclosed to me the pen of an author, master 

 of his subject, and of great research and acquirements. With some 

 difficulty and through the kind assistance of others I have recently 

 obtained the whole work, three volumes, the first and second in 

 German, the third in English. I learn that in Ijoth languages it 

 is out of print. I cannot but hope tliat ere long another edi- 

 tion of a work, every page of which is replete with information of 

 peculiar interest, will be published.
