John, The mark says "Lin Zhen-Fa Zhi" (made by Lin Zhen-Fa), the latter being a name.
The bowl...a bit difficult for me as it is at the limit of my range. The decoration looks more like Ming dynasty to me, but the glaze at the bottom could be later. So, I would say it is either Ming or Qing (Kangxi) dynasty. Good bowl. Please be sure to ask for a second opinion with this bowl. I am not sure if this sort of glazed bottom did exist in the Ming dynasty.
