We thus see that not only does what metaphysicians call the 
law of habit exercise a sway in the intellects of animals, but that 
modification wffiich takes place in human communities, and passes 
under the comprehensive name of civilization, also affects the 
lower tribes of creation. A race of animals, like a race of men, 
is civilizable; and we cannot doubt that the same softening in- 
fluences which have produced the advanced nations of Europe 
have operated upon the animals existing in the same countries, and 
made them very different from what they were in early times. It 
cannot escape remark, that the whole principle of civilization 
acquires strength from having its basis thus widened. We be- 
come the more confident in the i inprovability of our own species, 
when we find that even the lower animals are capable of being 
improved, through a succession of generations, by the constant 
presence of a meliorating agency.

NEPHRITIS AND PARAPLEGIA, COMPLETE OR INCOMPLETE, 
ATTRIBUTABLE TO SANGUINEOUS CONGESTIONS. 
By M. Berger, M. V. to the 5M Regiment of French Dragoons. 
Betw een the 20th of February and the 22d of March, seven 
or eight draught horses, as well in town as in the country, have 
been attacked by sudden palsy, wffien they have been drawing a 
hackney chariot, or some similar vehicle. All of them have died 
in a greater or less space of time, and generally in six days from 
the first attack. Three of these horses were seen by us. On 
this very day, March the 28th, some have died both in and out 
of the city. Others have been seen by M. Mannachas, a ve- 
terinary surgeon in the town, and by his colleagues. They were 
strongly-built horses, in high condition, and plethoric. Some 
of them fell almost as soon as they issued from the stable, 
others after going a long journey, or experiencing considerable 
fatigue. Not one of them had eaten from the time that they left 
the stable, until they w^ere attacked by this paralytic affection. 
They fell at once, and before their death discharged from time 
to time a quantity of urine, varying in intensity of colour from 
brown to almost black. The breathing, as well as the circulation, 
was considerably disturbed — they had painful tenesmus, and
