CLINICAL INSTRUCTION. 
they are fattened, they carry the fat too much upon the lean, 
i never give any meat to the young porkers designed to fatten. 
They run about in the yard of the farm, or rather, they graze 
where they please, and thus become perfectly fit for the table. 
When I want a larger animal for the house, I cross my breed 
with a good boar of the country, and the produce gives me that 
which i want—a great deal of lean meat, with sufficient size and 
aptitude to fatten. 
Swine suffer more than any other animals from being bred too 
much in and in. The number of young ones is reduced at each far¬ 
row, until at length the sows are barren. It is necessary to cross 
them from time to time when they begin to degenerate. The 
Chinese blood will probably afford the best cross, and, with proper 
precaution, can never be injurious. The best formed of this 
cross should be selected, and when they again are crossed back 
with the original breed, they will seldom degenerate. 
Young pigs, and particularly those that are disposed to 
fatten, are liable to some inflammatory diseases. Medicine will 
here be of little avail; but the prevention is very much in our 
power : the hogs should be suffered to range the pastures where 
they will find sufficient to nourish them, and keep them in health. 
It is an erroneous idea that they thrive better by being permitted 
to wallow in the mire : on the contrary, cleanliness is necessary 
to their doing well. When they roll in the kennels it is on ac¬ 
count of the heat of their blood, which would be best cooled by 
an abundant provision of clear water, to which they could always 
have recourse.

Toulouse: an extract from one of the 
Lectures of Professor Dupruyten.

[Journal Pratique, June 1830], 
Clinical instruction is essentially different from other branches 
of medical education. In the usual course of instruction, the 
Professor knows beforehand the subject on which he means to 
speak. He considers the different divisions of it, and gives it 
the extent and form which he pleases. He foresees and regulates 
every thing; and if he has but common talent, he can deliver a 
useful lecture, faithful to the plan which he has traced in the 
silence of his study. 
In clinical instruction, the rise and the cessation of disease; 
the changes produced by the natural course of the disease; by the 
variations of the atmosphere ; by the action of medicines; by 
food ; and by the operation of a multitude of other accidental
