EXPERIMENTS RELATIVE TO METEORITES. 341 



Specimens of divers nieteoric flescents had already been annexed to the museum. 

 With a view of develoijing tliis rising collection, I made an aj)i)eal, which has 

 been lieard in Europe and in different other regions of the globe, by numerous 

 persons desirous of promoting science. In 1861 the specimens, representing 53 

 falls, amounted in number to SO, weighing altogether 691 kilograms. On the 

 30tli of March, 1868, at which time a new and detailed catalogue was published, 

 the number of falls represented, embracing the discoveries of meteorites of incon- 

 testable origin but unascertained date, was 203 ; the number of the specimens 

 exceeded 550, and formed a weight of 1,682 kilograms. 



This collection, arranged at first in chronological order, has recently been 

 classified methodically, in confonnity with the principles of classification given 

 above.
