| Description | He has received from [William] Ramsay the proof of Main's report on Properties of Matter. Ramsay has mentioned their blunder regarding N2 O4, but he has not criticised Mr. Sidney Skinner's conclusions on the combination of PH3 and HCl. He discusses the experimental results on these, together with the key conclusions concerning vapour pressure. He quotes from two sections of Skinner's work, noting areas he does not understand. Young gives a table of calculated vapour densities of PH3, HCl and supposed mixtures at different temperatures. He comments upon this with regard to Skinner, and apologises for the length of his letter. He does not intend to attack Skinner, thinking that the fault lies with his advisor in recommending work with such extreme difficulty without previous practice. |
