at present is only problematical. The following results have Leen 

 obtained in connection with rabies in rabbits. If a rabbit is 

 inoculated with the virus of a rabies stricken dog, the rabbit becomes 

 rabid in 15 days. From this rabbit another is inoculated, and so 

 on in a series, the virus becoming quicker in its effe(t, and the 

 period of nicubatiou proportionately shorter, until the moculated 

 rabbit dies within seven days after the operation. Thus PiiSteur 

 has at his disposal a virus ranging from practically nil to a strength 

 which will kill iu a week, and his treatment is accordingly as 

 follows : Taking a dog he iuoculates him the first day with the 

 comparatively harmless virus, and on the following day the process 

 is repeated, until at last inoculations are made with virus only a 

 day old, and which is strongly virulent, no bad results whatever 

 following, although such an inoculation would be fatal to an 

 unprotected animal. A dog so treated is alleged to be rabies proof. 

 Pasteur had thus unfailingly experimented with 30 dogs, when in 

 July 6th last a boy was brought to him who had been severely 

 bitten by an undoubtedly rabid dog. From the following day to July 

 16th the boy was inoculated with virus ranging from a fortnight 

 until a day old, it becoming proved by simultaneous experiments 

 that after the first five days the same virus was invariably fatal to 

 rabbits, and now the boy is exceedingly well and pronounced cured. 

 Pasteur has several other patients under treatment, and expresses 

 the greatest confidence as to results. 



In the Graphic for November 2 1st last, there are two excellent 

 engravings of Pasteur and his " experiments for the cure of hydro- 

 phobia," yet the above experiments on the human body by no means 

 settle the question that we have as yet discovered a real antidote to 

 hydrophobia. In the first place the boy above mentioned may 

 never have had hydrophobia, even had he not been vaccinated with 

 the poison, for we know already that two-thirds of the people so 

 bitten do not contract the disease. 



Again sufficient time has not yet elapsed to show that the poison 

 is destroyed, supposing he had it ; for as I have already mentioned, 

 the incubation stage may in some cases last a twelve month. 



In yesterday's paper the following telegram, dated New York, 

 December 6th, appeared: — "The steamship Canada, which sails 

 on Wednesday next, takes four poor children from Newark, New 

 Jersey, who have been bitten by a mad dog, for treatment by M. 

 Pasteur. The expenses of the journey have been defrayed by pubhc 

 subscription." 



There is still remaining one plan of treatment of a preventive 

 kind, which, if carried out, would probably cause the extinction of 

 rabies entirely, and therefore of hydrophobia. Dr Fleming, in a 

 long and very interesting letter to the Times for November 26th
