§ Mr. T. WilliamsSome hundreds of cases of hypomagnesemia in cattle in this country have been reported to my Department by veterinary practitioners during the last six months, but as the disease is not compulsorily notifiable I have no actual figures either of its incidence or of fatal cases. Research into the disease has been carried out for several years at the Veterinary Laboratory of my Department at Weybridge and the results of this research, which has yielded a successful treatment, have been published from time to time in veterinary journals.
