Hi Ed, and ListJust writing to let you know a couple things about your last email "iron streams". I had that message come into my inbox, but it doesn't show on the met-list archives, at least not yet. Likewise, I see messages on the archives from quite recent that never showed up in my inbox. I'm sure there is a logical explanation for all this. I guess I was just wanting to point it out as a possible reason for you not getting a response (on list) to your questions. If you did, they were off-list. About the only way I have found to keep up with some of the current List threads is to refer to the archives every so often and compare those messages with what I get in the inbox. Which is no problem.
On your topic of "iron streams", I can't offer anything worthwhile on the relationship between any of those falls, but here is something I saw in an old book titled: "An Encylopædia of Practical Inforfmation and Univeral Formulary for Every Occupation, Trade and Profession" by Robert Bradbury, M.D. Print date of 1889. I just thought this part was interesting and that you might like to see it.
"Aerolites, meteors, and falling stars all seem to have a common origin. They are produced by small bodies--planets in miniature-- which are revolving, like our earth, about the sun. Their orbit intersects the orbit of the earth, and if at any time they reach the point of crossing exactly with the earth, there is a collision. Their mass is so small, that the earth is not jarred any more than is a railway train by a pebble thrown against it. These small bodies may come near the earth and drawn to its surface by the power of attraction, or they may simply sweep through the higher regions of the atmosphere, and there escape its grasp; or, finally, they may, under certain conditions, be compelled to revolve many times around the earth as satellites. Indeed, a French astronomer estimates that there is one now circling about the earth at a distance of 5,000 miles, This companion of our moon has a period of three hours and twenty minutes. The average velocity of these meteoric bodies or bolides, as they are frequently called, is thirty-six miles per second--much greater than that of Mercury itself."
