of the Local Government Board, who had been interested 

 in our earlier observations on oysters in connection with 

 disease, now began to come into close relation with our 

 work on mussels and cockles. He took part with Mr. 

 Johnstone in visits of inspection to beds in Lancashire and 

 Xortli Wales, and came to Liverpool on several occasions 

 to consult with us in regard to the co-relation of bacterio- 

 logical and topographical evidence and the possibilities 

 of remedial measures — a matter in which he took the 

 keenest interest. Dr. Bulstrode's premature death last 

 3'ear is a severe loss to public health sanitation in con- 

 nection with shell-fish, a subject he had made peculiarly 

 his own by the two admirable Reports he prepared for 

 the Local Government Board, the first on oysters, pub- 

 lished in 1896, and the second on other shell-fish in 1911. 

 We have been in communication also in recent years 

 with other Government Officials, and with Public Health 

 Uflicers of several neighbouring towns and districts, and 

 some of our recent bacteriological investigations wer(> 

 undertaken in consequence of these communications. It 

 was, for example, a statement received from the Medical 

 Officer of Health of an inland town that gave rise to 

 Mr. Johnstone's report on the bat^teriological conditioji 

 of the mussel beds in the Estuary of the Wyre. It is 

 clear tliat although the degree of pollution is not so great 

 there as in other known cases, the examination was very 

 desirable, and further investigation of that neighbourhood 

 may become necessary. The importance of such work, 

 carried out in cd-opcrat ion with th(> Public Health Uflicci's 

 of the towns to which shell-Hsh arc consigned, can 

 scarcely be over-estimated, and it is gratifying to liiul 

 that Dr. Bulstrode, in his recently published " Report 

 on Shell-fish other than Oysters in relation to J)isease " 

 (Local Government Board, Cd. 5313, 1911), refers in
