CHAP. I.] CONTROVERSY ON AIR CELLS. 235 



broken, or burst into each other through great ex- 

 ertion, then the air escapes with difficulty, and the 

 expirations are now slower than the inspirations (as 

 before said), and both together constitute irregular 

 respiration, or true broken wind. 



But of controversies there is no end. James 

 White and Richard Lawrence were for some years 

 at issue on these points ; White having taken up 

 Lawrence rather sharply, and somewhat unjustly, if 

 he meant to impute error to the latter, as regards 

 the symptom of respiration just spoken of, for each 

 writer was right in his separate position : as they 

 disagree as to what constitutes broken wind, so 

 they could not of course agree as to the symptoms. 

 See pages 159, 160, of White's first volume. This 

 author also disorders his own positions at the same 

 place, in two other instances, which we should not 

 have noticed but for his tart rebuke of Lawrence 

 for attributing the term broken wind to the thicken- 

 ing of the membranes. In this view of the case, it 

 will be seen, we cannot agree with that very clear- 

 headed veterinarian to the full extent ; but we do 

 not, therefore, harshly refute a gentleman and scho- 

 lar for not agreeing with us upon a simple term of 

 science. 



WJiite says, page 160, " The lungs of broken- 

 winded horses that I have examined have generally 

 been unusually large, with numerous air-bladders 

 on the surface." Yet, in the next page, he opens 

 a broken-winded subject, and says, " The lungs 

 were lighter (meaning less) than usual, and without
