the hunter would average a life of 20 or 25, and 1 in this number 
would be the annual death. 
7. The most prevalent diseases are inflammation of the respira- 
tory passages and inflamed lungs, with pleurisy and diseases of 
the bowels. 
8. The most fatal, inflamed lungs, with pleurisy. 
9. The diseases of young horses are strangles and inflammation 
of the respiratory passages ; the latter the most fatal. 
9 and 10, Can readily be deduced from the above answers. 
I should say the proprietors of horses will not feel much dis- 
posed to insure their lives, the greater number being rendered use- 
less by accidents and lameness. 
Mr. Beeson requests us to correct our report of his answers, 
inserted in the last Number ; and in reply to the 6th query, thus 
writes : — “ I said that, in addition to the rate of mortality I had 
previously stated, and which died under my treatment, an allow- 
ance must be made for some that may have died suddenly, and 
without any treatment ; and also for others that may have been 
slaughtered, and of which, of course, I could give no account.” 
In reply to the 10th, “ As to the proper age to insure our horses 
he mentioned the instance of the foal, to shew that an insurance 
at an early age is necessary to secure the farmer against loss.” 
AN ESSAY ON FAT AND MUSCLE.

As we proceed with our subject, it will be found that some of 
those characteristics are in a great measure dependent on internal 
organization ; and accordingly experience has proved that animals 
possessing small lungs, small livers, and small spleens, indeed 
“ small offal” of every description, have a greater disposition to 
fatten and to lay that fat on proper places, which we consider to 
be a fair proportion of fat and lean, than coarse-bred ill-propor- 
tioned animals, which will be found to possess larger offal than 
well-bred animals in proportion to their size and growth. We can 
clearly understand the reason of this, since we now know that the 
less quantity of oxygen an animal consumes, the fatter it becomes ; 
for small lungs cannot decarbonize as much blood as large lungs, 
nor can a small liver secrete as much bile as a large liver, bile 
being formed in the herbivora from the non-nitrogenized materials 
of their food; hence a larger quantity of carbon is used in the
