近50年来，文献中一直存在某些错误，这些错误涉及到从垂直圆柱体的下圆面悬挂的最大液滴的重量和福尔斯的液滴的重量，但没有得到充分的纠正。诚然，在这一时期，甚至在更早的时期，已经出现了对这个问题的正确处理，但并没有减少错误的流行。不幸的是，其中最突出的一点，即福尔斯下落的水滴的重量等于一个常数乘以尖端的周长，仍然得到著名教科书的声明的支持，即它对于实际目的来说是足够准确的，尽管可能包含高达60%的误差，但他们没有说明这一点。
FOR nearly fifty years certain errors, which concern the weight of the maximum drop of liquid which will remain hanging from the lower circular face of a vertical cylinder and that of the drop which falls, have been present in the literature without adequate correction. It is true that during this period, and even earlier, correct treatments of the subject have appeared, but without the effect of diminishing the popularity of the errors. Unfortunately, the most prominent of these, that the weight of the drop which falls is equal to a constant multiplied by the circumference of the tip, is still given support by the statement of prominent text-books that it is sufficiently accurate for practical purposes, even although—but this they do not state—errors of so much as 60 per cent. may be involved.
