Miscellanies. 411 



Mr. Oakes informs us that the marl, now mentioned, is on the 

 Chesapeake Bay, about sixty miles from the capes, and the deposit 

 is so extensive that millions of bushels may be obtained. It is con- 

 venient to navigation, and it is supposed that it may be delivered 

 on board of vessels at four or five cents a bushel. How far this 

 material may admit of transportation to distant states we cannot say, 

 but it admits of no doUbt that on certain soils it must be a very val- 

 uable manure, and we should be pleased to have the experiment tried 

 within those States, which can obtain it with facility. 



The subject of marl has received but little attention as yet in this 

 country, parts of the Western States, and particularly in the eastern 

 states, while it is well known that it is highly efficacious in other 

 countries, and in some parts of this. On the territory of James 

 Wadsworth, Esq., and of his brother. General Wadsworth, at Gen- 

 eseo. New York, the soil contains a natural marl, which renders it 

 permanently fruitful in the production of wheat so that it needs not 

 the usual additions of animal and vegetable matter. 



12. Iodine in Angina Pectoris. — The case of Dr. B. Lynde 

 Oliver, was mentioned in Vol. XVI, p. 176. From the same gen- 

 tleman, under date of May 28, we derive the following statement. 



Mr. Worthington, near Baltimore, had been for about five years 

 afflicted with the Angina Pectoris, to such a degree, that while walk- 

 ing he was obliged to stop and stand still two or three times in every 

 hundred yards, and during the above period he had no intermission 

 of his symptoms. He then took the Iodine, agreeably to Dr. Oli- 

 ver's prescription,* and in one fortnight was able to walk six miles 

 without any inconvenience, and with no more fatigue than he had 

 usually felt when his health was good. On a return of the symp- 

 toms, the iodine was again and again resorted to, and as often as- 

 suaged the complaint. In a more recent letter, Mr. Worthington 

 says that he has for seven months enjoyed good health, having a re- 

 gular pulse, and no symptoms of the Angina Pectoris, except from 

 great fatigue or excitement, although he was occasionally seized with 

 great weakness. With an abstemious diet, a regular hfe, and an 

 issue in his arm, he had been able to live for a good while without 

 the iodine.

 with six drops, and gradually increasing the dose to 16 or 20-
