102 APPENDIX. 



had a note taken at his lectures by a gentleman within two 

 years of his making it, which contained a similar declaration, 1 

 and afterwards I said that I had written to such gentlemen as 

 I knew had, as well as myself, attended his lectures within 

 these eight years, desiring them to consult their notes, and to 

 let me know what Dr. Monro had said as to the existence, or 

 non-existence, of the lacteals and lymphatics in these animals ; 

 without mentioning the dispute between us, or any opinion I 

 had formed, that they might be unprejudiced to either party. 

 And that such of these gentlemen as had taken notes sent me 

 excerpts from them, which, as I had suspected, agreed with 

 what I had myself heard the professor say upon that subject. 



That Dr. Haygarth, physician at Chester, had sent me the 

 following passage from the notes which he had taken in 1764. 



" Fowls, and some fish," says Dr. Monro, " have not lacteal 

 vessels that we can see ; they have no conglobate glands in the 

 mesentery ; perhaps they (the lacteals) do not run into each 

 other, but into red veins, and hence never are so large as to 

 become visible." 



" This note," adds Dr. Haygarth, " was taken in 1764, and 

 if Dr. Monro had changed his sentiments on this subject in 

 the year 1765, 1 should certainly have taken notice of so remark- 

 able a circumstance." 



That, from Mr. Orred, surgeon at Chester, who attended 

 Dr. Monroes lectures during the winter 1765-6, I had learned, 

 that Dr. Monro, when he spoke of the anatomy of a cock, 

 declared : " he never saw, or observed any glandulse vagse, or 

 lacteals, but had seen lymphatics in the neck, ending in the 

 jugular." 2 



1 Dr. Monro has misinterpreted this passage. He supposes I meant that this note 

 was taken two years before 1762, whereas I meant two years before 1768, the time 

 when he claimed these discoveries, and when I wrote my letter to the Secretary of 

 the Royal Society. The note itself is printed above, p. 98. 



Dr. Monro has taken notice of another inaccuracy, that is, where I had said, " He 

 asserted that he had anticipated me in these discoveries;" instead of saying, "that 

 he claimed them by asserting he had injected," &c. The former Dr. Monro seems 

 to allow to be what he meant, but not exactly what he said. It was therefore a 

 small inaccuracy ; but his claim is now printed verbatim. See above, p. 96. 



2 It may be necessary to mention here, that the dispute between Dr. Monro and 

 me is, who first discovered the lacteals of birds ? for as to the lymphatics in their 

 necks, (mentioned in this gentleman's note,) these we both allow were discovered by 

 Mr. John Hunter, about ten years ago.
