 named rhodii/m, and showing that palladium might be got 

 from criulc platina. He had sonic yeavs ago purchased 

 a considerable quantity of platina with a view to make it 

 malleable. In the course of his experiments he found out 

 the palladium ; but observing that there were yet many phae- 

 nomena which could not be explained, he wished to secure 

 his claim to the discovery without directing the attention 

 6f chemists to a subject he desired to investigate more fullv. 

 He afterwards detected the other new metal, rhodium, the 

 presence of which unknown body "was one cause of the dif- 

 ficulties which presented themselves. Having now finally 

 completed the analysis of crude platina, we understand he 

 intends to give a detailed account of its composition, and 

 of such properties cf the new metals as he has since. l^cen

ORIGINAL A'ACCINE POCK INSTITUTION. 



At the quarterly court held 'on the Sgth .January, a cri- 

 tical examination of Mr. Goldson's second pamphlet was 

 feftd by Dr. Peort-on. We are sorry oUr limits do not admit 

 of our laving before our rcatlcrs more than the concluding 

 remark of Dr. Pearson, which was a.t follows : 



" Dr. Pearson repeats his proposal to Mr. Goldson, of 

 coming himself, or deputing two friends to' the Vaccine 

 Pock Institution, to decide the qiiestioned facts by experi- 

 nienls, and lay the issue before the public. In the mean 

 time Dr. Pearson, in the name of the institution in general, 

 and his own in particular, returns his acknowledgment ro 

 Mr. Goldson for provoking the investigation of a subject 

 which is so much wanted to obtain precision in practice, 

 which has been cheeked hitherto bv so manv pretenders to 

 knowledge of the subject, and v>ho would wish it to be 

 believed that the history of vaccine inoculation was ex- 

 hausted by the publication of half a dozen instances of 

 inoculated cases on the .promulgation of the new jjractice. 

 Dr. Pearson willingly concedes to Mr. Goldson, that a test 

 of security is wanted for many of those who have been or 

 shall be inoculated, because a criterion has been wanting 

 to guide practitioners, and determine whether constitu- 

 tional affection was produced or not ; and that, admitting 

 that even all the adverse cases published are cases of small- 

 pox after cow-pock, which does not appear to be the truth, 

 they will only serve to regulate practice in future ; for the
