The extreme variation in Forest calves found dead in spring is 63 variations in (79 found 1 88 1 1 6 found 1886). We add largely to the calves cleat s of Deer not found dead in Forest for our estimates of deer. The extreme serious inStags variation thus becomes 96 (120 supposed dead 188124 in 1886). or Hmds - The death of stags is not alarming, especially during the last 5 years. The death of hinds is curiously light it compares very favourably with the death of stags. I think it amazingly small considering that no old hinds are shot. But the death of calves Serious varia- . . tionsm death on some occasions has been very disquieting; it appears to have of Calves. reached 55 per cent. (1881) and to have fallen as low as 9 per cent. (1886). We are sadly ignorant of the causes of these great variations, but we are very suspicious about husk disease being the chief cause. The late Duke of Portland lost above half his herd of red-deer at Welbeck from husk. The park keeper gave Husk perhaps the cause. me strongylus micrurus as the name of the parasite. This was about nine years ago, probably the year 1881. We did not count Forest stags in 1878 ; we guess them at 525. At that time stags had not taken to the glen and low ground of Largy, so they were less spread than at present, and looked more than their number. In 1879 we know the lost count of Forest was about 500, because Murchison remembers Angus McKay (senior) so firmly holding and expressing the opinion (formed without data) that it was impossible there could be 500 stags in Forest. The count of 1880 is lost (except for Tarbert), and count of 1881 was
