Mr Ch. Trlfair, Governniont Commissioner at Sey- 

 thtlles, has su^'gosted the idea of renioviuj? the dorsal 

 slicll from the turtle, without destroying the animal or 

 evpu pndatigering its lif", it havii g t"he property of 

 ffrowin<'' agtin Thi-^ object is to prevent the destruc- 

 tion of a necessary article of food. Hundreds of the 

 turtles are killed in the season to obtain from each one 

 pound and a half, or one pound three quarters of tur- 

 tnise shell worth from Is 6d to 2s the pound, the cai- 

 cast s are thrown iiitd the sea or left on the beach, and 

 a lar'^e quantity uf wholesome and nutritious flesh is 



lost. 



The operation has already been tined. and it is said, 

 with success. "1 lie turtle, deprived of its dorsal cover- 

 ii!", after a certain time recovers a new shell, as occurs 

 occasionally wiih other animals who lose a nail or oth»r 

 ■integument of the same kind.

This object is to sheAV that no disease foreign to 

 the vaccine virus itself can be transmitted with it, 

 whatever may be the pathological state of the indivi- 

 dual from whom it is taken. His arguments rest upoii 

 statistical returns which apfiear to be comlusive, and 

 also, upon the results of numerous experiments tried 

 in 'iifferent countries of Europe. He particularly ad- 

 verts to those mentiuned by Mr Taupin, physician, in 

 ch'irge of the Hospital "des enf-mts malades" at Paris. 

 They tend to prove that the vaccine virus always re- 

 t;iiiis its activity and remains isolated, even when mix- 

 ed with some other virus. If, for in^tanc^', it is mixed 

 with the virus of small pos, the tw.) maladies may be 

 SRen, after the inoculation, developing themselves and

Dr Taupin s lys that he hns vaccinated upwards of 

 rwu thousand subject.*^, in every roudition of he.ilth and 

 afff". n"d has observed with the most minute attention 

 <l\e progress of the vacination during fvcry stage.
