the feelings of oratory, and the passions of })oetry, and it has been 

 worn away by degrees, as the crystal in the stream is worn to a 

 pebble, till it has returned to a simplicity which wears the aspect 

 of the immediate offspring of the Chinese or Egyptian or Mexi- 

 can Hieroglyphics. But with all this, it has still some spots, some 

 idioms, which invariable custom obliges us to retain ; and which 

 can only be distinguished from corruptions and vulgarisms by 

 tracing their history through the different stages of its progress, 

 including, of necessity, the corresponding idioms in the parent 

 languages out of which it has arisen. 



Believe me always, my dear Sir,

Malaria : an Essay on the Production and Propagation of 

 this Poison, and of the Nature and Localities of the Places 

 by which it is produced, with an Enumeration of the Dis- 

 eases caused by it, and of the Means of diminishing and 

 preventing them, both at Home and in the Naval and 

 Military Service. By J. Mac Culloch, M.D., F.R.S., 

 &c. &c. Longman and Co. 1827. 



Though we have given a place in our Journal to two 

 articles on Malaria from Dr. Mac Culloch, we have thought it 

 expedient to take some notice of his book under the form of 

 a review ; particularly as some matters have come under 

 our cognizance, which may add some illustrations to this 

 subject where the author appears to have been in a state of 

 deficient information, or to have shunned the question for 

 reasons which appear to us somewhat over refined. 



We allude principally here to the localities and the facts, 

 as they are now before us ; circumstances and events which 

 seem to us of the greatest importance, as enforcing the value 

 of the details which he has collected, and as holding out 

 warnings to the people respecting the preservation of their 

 healths, in addition to those which the work before us has 

 given in describing the soils or characters of ground in 

 England from which this destructive poison is generated. 

 And before we proceed to the analysis of his book, we shall 

 state what those are, or at least a few of them., while won- 

 dering that he should have overlooked them, or regretting 

 that any fancies should have prevented him from stating 

 what would have been of so much utility.
