of vaccines once prepared may be preserved without great difficulty. Since the 

 inoculation of a susceptible animal tends to increase the virulence of the virus, it is 

 advised that one employ the least susceptible animal that the same virus is capable 

 of killing, and for an example he suggests that a No. 2 virus should be passed 

 through a guinea pig rather than a mouse. In support of his conclusions, the author 

 gives several tables showing the history of his viruses, all of which are continued 

 from the Annual Report for the year 1895. 



Combating anthrax in Delaware, A. T. Neai.e (Delaware Sta. Rpt. 1896, }>p. 

 7-35).— This is a reprint of Bulletin 32 of the station (E. S. R.. 9, p. 92) with the addi- 

 tion of several paragraphs relating to culture tests, 4 tabular records of tests, and 

 cultures, and a table, closing the vaccination experiments to July, 1896, of 7 mice 

 and 1 guinea pigs, tested with vaccine No. 1. All the mice died on the second day and 

 all the guinea pigs survived. With the mice the results were the same in the ease 

 of vaccine No. 2. Of the guinea pigs 60 per cent died, while all the rabbits tested 

 survived. With vaccine No. 3, all the guinea pigs died and all the rabbits survived.

 Acad., 2. sir., 11 (1894), pp. 302-320). 



Recent investigations on the' hepatic nodules and observations on the pul- 

 monary nodules of the horse, li. Gai.li- Valekio (II 2Foderno Zooiatro, vol. ■', No. 9; 

 abs. in Centbl. Hall. n. Par., 1. Jbt., 21 (1897), Xo. 22-23, pp. 886, 887).— It was found 

 that in the liver of the horse the emboli arising from distomid eggs in the smaller 

 gall passages cause a nodular formation in which as many as 20 eggs of Distomum 

 lenceolatnm may be found. Calcareous bodies due to an unkown nematode larva 

 were also found in the lungs. These bodies might give rise falsely to a diagnosis of 

 glanders. 



Animal and vegetable parasites associated with the production of neoplasma 

 in cattle and sheep, A. Park ( Trans, and Proc. New Zealand Inst., .'S (isrt.',\, pp. -/;/-

Intestinal parasites in China (Rev. Sri. ( Paris), 4. see.. S (1897), No. 15, p. 17:2). — 

 It is noted that certain ascarid parasites are so frequent at Pekiu that 95 per cent of 

 the children are attacked. The same parasites are very frequently found in adults. 

 They enter the system with drinking water and leguminous plants, which arc 

 frequently eaten raw by the natives. Europeans who boil or filter their drinking 

 water and cook their fooil are seldom attacked. Tapeworms are not at all common 

 among the natives, since little meat is consumed.

Agricultural returns for Great Britain, 1896 (London: Eyre d: 

 SpottisH-oofle, 1890, pp. 283, mops 2). — This report embraces 124 tables 

 showing the acreage and production of crops, prices of grains, and num- 

 ber of live stock for Great Britain, and giving general agricultural statis- 

 tics for the United Kingdom, British possessions, and foreign countries. 



The number, size, distribution, and character of agricultural holdings 

 in (heat Britain have been made the subject of special inquiry during 

 the past year. From the figures given, it is shown that 51.48 per cent, 

 or more than one-half of all the holdings of Great Britain exceeding 1 

 acre in extent, were of the type of small farms not exceeding 20 acres 

 in extent. Farms above 20 and not exceeding 50 acres in extent 

 accounted for about 16.5 per cent of the holdings and farms between 50 

 and 300 acres accounted for about 28.5 per cent, while " the number of 

 large farms with more than 300 acres of cultivated land form very little 

 over 3.5 per cent of the holdings."
