    these cases the snurees nf infection were found, and fifteen cows with tuberculosis of the udder and one with definite clinical signs of tuberculosis and chronic cough were slaugh- tered. In four instances no source of infection could be traced, and in two cases involving milk from depots dealing with hundreds of herds, it was impossible for any useful action to be taken. Milk Sampling. As has already been stated, during the year 2,406 samples were taken under the milk sampling scheme. The sampling concerned graded herds, pasteurised milk and samples from school and institution supplies which include both graded and ungraded. Included in the 2,406 were 646 from ungraded supplies. The following table shows the results of the examination of ungraded supplies :— Saniiarv Area- Table I. Rural. SaHsfactoyv. Unsalisfacloi'V. Total.

It may ])erhai)s be u.seful and it is only fair in this connection, to point out that the term “ unsatisfactory ” as applied to milk samples includes not only those which arc thoroughly bad— for example reducing methylene blue in .1-hour, or containing colilorm in three tubes—but also tho.se which just miss passing both tests, in which, for exam[)le, coli are absent, and the reduction of methylene blue almost reaches the rciiuircd standard. “ Unsatisfactory ” therefore, is capable of rather a wide intcri)rctation. As in liUl, the worst results come from the Millom and I’enrith Rural districts.
