Griffiths, all of whom shared Prof. Hering's curiosity in leaf-miners. even if Dr. Buhr is basically a botanist, with Hering's encour agement he has taken an energetic curiosity in leaf-miners all through his profession and his amazing gathering turns into obvious from Hering's letters to him. for a few years Prof. Hering has written among and 3 thousand letters every year. It has evidently been attainable to think about the following just a very small share of those. From the various longer letters simply remoted paragraphs were integrated. Use of italics within the letters used to be now not totally constant and has been reproduced as utilized by Prof. Hering. number of the letters has been established totally on their entomolo gical curiosity yet a number of passages have additionally been incorporated illustra ting in a roundabout way Hering's own traits.
