Cf. op. cit, 1853, pp. 96-108. 65 spp. The present article retraces the ground of the first 

 one ; the discrepancies between the two are numerous and irreconcilable, leaving both open 

 to suspicion. In fact, having ourselves suffered for our indiscretion in venturing upon these 

 papers of Bruch's, as well as those of Bonaparte's on the same subject, it is a duty we owe to 

 posterity, and one we willingly here discharge, to warn all persons off these premises.
