334 ANALYSIS or CONTINENTAL JOURNALS. 
The next day (9th) a lady's maid, who had been at work 
in the room where the dirty linen of the “ Floride” had been 
counted, was attacked with smallpox. 
This circumstance accelerated the revaccination of the 
crew of the “ Nouveau-Monde,” and on the 10th, 11th, 12th, 
and 13th of February, the whole of the passengers of the 
packet were revaccinated. One half of the revaccination 
was followed with the characteristic pustules, the evolution of 
which did not cause any claim for exemption of duty amongst 
the crew. 
On the 25th of February two sailors were embarked at the 
Port de France, and on the 26th they were attacked with 
varioloid ; but notwithstanding that there were now on board 
three persons with smallpox, none of the crew or passengers 
were attacked with it. The revaccination had, to all intent, 
its full effect; all those who had been submitted to it, 
whether it produced pustules or not, were preserved. It was 
evident that in those cases where no pustules were produced, 
the individual was under the influence of a previous vaccina- 
tion, which was still efficacious, and there is no doubt that of 
the 250 on whom the vaccination had been followed by the 
pustules many would have been contaminated. 
The Transatlantic Steam Navigation Company, struck 
with these results, embarked vaccinated heifers on two others 
of its steamers employed on the service of the Isthmus. The 
heifer on board the “ Nouveau-Monde” had 150 w ell- 
developed pustules, enough to vaccinate 2000 persons, and 
there were only 500 on board. This enabled the doctor of 
the vessel to fill a great number of tubes, w'hich had been 
supplied by M. Lanoix for the purpose, to be distributed at 
Port de France and Panama, in order to calm the alarm of 
the population, who found themselves without protection 
against this fearful calamity. 
This is a great triumph in favour of animal vaccination, 
and the young medical man who persevered throughout the 
greatest difficulty at the risk of his reputation and at great 
sacrifice, has thus multiplied the precious means of preserva- 
tion against this fearful malady. With the name of Lanoix 
must ever be coupled the honour of having rendered a signal 
service to his fellow r -men, and these services of our colleague, 
we trust, will not remain without the reward due to them. 
The experiment on board the “ Nouveau-Monde" is most 
conclusive; 250 persons presented characteristic pustules, 
and were protected, though in a close confined space, in 
which were three individuals affected with smallpox, and 250 
on w hom no pustules appeared, and who, notwithstanding,
