it is preferable to collect the first day's or at most the second day's crops only partly because minute globules of mercury get entangled among the M►188 of the crystalline deposit which it is tedious to get rid of and partly because the coposition of the salt varies on standing in the liquid. [...] In determining the composition of the salt the amount of mercury in it will have the predominating voice on account of its high atomic weight; the nitrogen playing only a minor part. [...] In the case of very dilute solutions of alkaline nitrites and nitrates it is generally the custom to take a larger volume of the liquid evaporate it to dryness and then dissolve the residue in the minimum quantity (say 2 c.c.) of water Bat unfortunately this could not be done in the present case as thereby insoluble basic salts were formed. [...] 9 The place of mercury in the Periodic System would naturally justify the expectation that it would yield the analogue of silver nitrite and the present compound is a realisation of it. [...] The limitation of genera here has given even greater trouble than in the case of Papa veracete proper while of late years systematists have bad to contend with a complicated synonymy duo to a well-meant but the writer believes too rigid application of the rules regarding priority of nomenclature: As in the present paper the writer adheres both to the generic limits and the generic names of the
