✦ Synopsis

The extractlon of boron from rocks by methyl borate dlstdlatlon after alkah fushlon was studled Reproducible extractlon was obtamed when the ratlo of the amounts of flux and rock was b 5 1 Isotope ddutlon expenments showed there was no appreciable boron Isotope fractlonatlon dunng the extractlon under these condltlons. "B/"B ratios for three standard rocks were 4 044-4.047.
