Doctor of Physick & fellow of the colleg of *** : wherein many errors are corrected, touching the nature of these two salts / by Fran. Andre, Dr. in Physick ..., faithfully rendered out of French into English by J.W. ; to which is added, by the translator, a discourse of phlebotomy shewing the absolute evils, together with the accidental benefits thereof, in some cases.; Entretiéns sur l'acide et sur l'alkali.

that_o the_o fermentation_n or_o heat_n and_o ebulition_n which_o be_v cause_v when_o these_o two_o salt_n be_v mingle_v together_o be_v a_o sure_a token_n to_o know_v acid_n and_o alkali_n for_o he_o
