| Description Of Item | He thanks Cullen for his kind remarks on his paper on variolous contagion. He took up Cullen's suggestions as to sources he should refer to as he had never read 'any account of the Plague, except [Thomas] Sydenham's and one or two still more imperfect than his'. He encloses alterations and additions to the Inquiry (into small pox) and asks for Cullen's comments. The alterations and additions are in four sets. The first and second, as Haygarth writes in his letter, 'more distinctly stated the chemical arguments' and relates to the mode of combination between variolous miasma and air. The third 'will ascertain...the limit where the small pox begins and ceases to be contagious in the open air' and the fourth contains the rules of prevention established by the Small Pox Society (see CUL/1/2/863/). |
