104 APPENDIX. 



with bread soaked in milk, and tinged it by turns with blue, 

 madder, and saffron, and afterwards opened them at several 

 different times, in order to discover the lacteals, but all without 

 success. Yet, perhaps, the lacteals may be in fowls, though 

 not demonstrable." This, adds Mr. Hull, I will answer for 

 being verbatim, or nearly so, as Dr. Monro delivered it in 

 the anatomical hall, at Edinburgh, on the 13th of February, 

 1765. 1 



These passages, I added, were sufficient to show how little 

 right Dr. Monro had to these discoveries, Besides, I said it 

 was a strong argument against him, that in the letter I had 

 received (which he has printed in his ' State of Facts/ p. 8,) 

 he could not, after relating all his experiments and observations, 

 conclude he had really seen those vessels as he had told the 

 Royal Society ; but in one place he says, " that, from the pre- 

 ceding experiments, &c. it is evident that he had seen what he 

 suspected to be the lacteals in birds." And in another, " that 

 he was himself persuaded that birds were provided with lacteal 

 vessels, and confirmed in this opinion, by having now injected 

 them in one of the same oviparous class, the turtle/' 2 



Such conclusions appear merely evasive, and never can be 

 considered as proofs of his having discovered those vessels 

 before I did, agreeably to his assertion read before the Royal 

 Society, and since repeated in his ' State of Facts/ 



The half-sheet of paper, containing these arguments and 

 testimonies against Dr. Monro, was printed Dec. 1, 1769, and 

 was given to such gentlemen of my acquaintance as had heard 

 of his claim, and a copy of it was sent to the Doctor. Upon 

 receiving which, he published his * State of Facts ? but what is 

 singular, he has attempted his justification without taking pro- 

 per notice of these testimonies against him ; as if he could be 

 justified whilst they remain unanswered. And in this ' State 

 of Facts', in spite of those testimonies, he repeats to us, " that 

 long before 1762, he observed blueish vessels in the mesentery 



1 If the reader will take the trouble of comparing this note with Dr. Monro's own 

 account of his experiments, (State of Facts, p. 12,) he will be convinced how accu- 

 rately this gentleman must have taken notes. 



2 This argument was repeated in a note, to prevent Dr. Monro's writing ; as if the 

 dispute between us was, who first had suspicions about those vessels, instead of who 

 first discovered them.
